Most of the lead-acid batteries in our UPS system will last 5 years, Nickel-Hydride batteries and Lithium-Ion batteries will last 10 years when the surrounding temperature is 25°C/77°F according to the respective battery manufacturers. An automatic battery health check (Default is set to every 6 months) will inspect the battery discharging voltage and will beep to notify you if it detects lower voltage than the normal.

Our UPS is also programmed to notify you with a beep when the battery needs to be replaced based on the period of the time calculated and by the surrounding temperature. The default is 4.5 years with 25°C/77°F since the initial installation. The higher the temperature, the sooner you would hear beeping and vice versa.  

The beep will be triggered by whichever comes first. (For this reason, you will need to reset the battery information when you change the internal battery pack. You can find the battery reset instruction in the product manual).

SANUPS products all have hot-swappable batteries. The cable connector and battery pack housings are designed with easy and simple maintenance in mind. Please note that the UPS systems are UL listed and CE marking products. To keep these labels, please ask our field support to replace the battery.

– Tips for replacing the battery pack –

When you change the battery, please be sure to wear insulated gloves and shoes. It is also a good idea to remove rings, necklaces, and watches. Using insulated tools is also the best practice. Please do not use a third party battery or mix up old and new batteries. Using the same battery longer than its product life may decrease the backup run time and the worst case, catch fire.

Total Battery Capacity (Ah・Cell) can be calculated by the formula below.

  Capacity (Ah) of One Battery-Pack

x Number of Cells in One Battery

x Total Number of Batteries in series

x Total Number of Batteries in parallel (Exclude this line if there is no parallel)

x Number of Charging Circuits

The lithium-ion battery has dramatically more battery-charging cycles compared to a lead-acid battery which makes the product life so much longer. Besides, Lithium-Ion batteries are small and lightweight and fit in many small electronics such as a mobile phone or laptop computer.

The power of electricity that a Lithium-Ion battery produces is powerful which means it requires a charging voltage control at the highest level. Also, Lithium-Ion batteries cost more than lead-Acid batteries because of the material it uses.

SANUPS A11K-Li finished its development and is expected to be released in early 2019.    

Lithium-Ion Batteries tend to have a complex charging circuit because it is susceptible to charging-discharging. If the voltage control is not thoroughly managed, it may result in a significant accident and this has been a big challenge to many electronics manufacturers.

Our SANUPS A11K-Li was not an exception. To overcome such a challenge, A11K-Li monitors temperature, charging ratio, and voltage information by CAN communication. With this communication, the UPS circuit and Lithium-Ion battery will be completely separated in case of over-charge, over-discharge, and short-circuit. This technology makes A11K-Li UPS safe and user-friendly.  

If you were to store the Lithium-ion battery UPS, please remember the points below.

1: Lithium-ion batteries get more impact from the environment than a lead-acid battery.

2: If the Lithium-ion battery is fully charged, it becomes progressively worse faster. In other words, Lithium-ion battery deteriorates slower when it is less charged.  

3: If a Lithium-ion battery is completely discharged, it will not be able to fully recharge.

4: A lower storing temperature is better for Lithium-ion batteries.

Uninterruptible power supply (UPS) is a power supply system that contains a rechargeable battery to provide power to the load equipment in the event of a power outage. Several reasons cause the power fluctuations including power outage, voltage dip, voltage spike, brownout, noise, and frequency fluctuation. The Power Basic Knowledge page explains those causes in depth.

There are three different topologies for Uninterruptible Power Systems; Online, line-interactive, and standby.

Online UPS is also known as a double conversion that accepts AC input and rectifies to DC and then inverts back to 120 V/208 VAC to feed the electricity for load equipment. Since Online-UPS converts the power twice on the circuit, it is called “Double Conversion” and outputs a pure-sine wave which is favorable for the load. On the main circuit board, there is a dual-directional circuit for the rechargeable battery. This rechargeable battery will back up the load equipment during a blackout. There is no power down when the power source transfers from a double-conversion circuit to the rechargeable battery. Online UPS is the most reliable UPS, and it is the reason why many manufacturers have employed SANUPS for highly critical loads in various industries.   

Line-interactive UPS is similar to offline UPS in its circuits but enhanced by the adding a transformer (voltage regulator) to condition the utility power. It slightly improves efficiency and reduces battery usage. Though Line-interactive UPS is not as reliable as Online-UPS, it is still prevalent among the consumer and IT professional markets.

A Standby UPS powers the load directly by commercial power. There is no modification added to the output by the UPS. A Standby UPS only invokes when the utility power fails. In other words, Standby UPS would not protect the load from unfavorable power conditions. This type of UPS does not require as many parts as an Online-UPS, and it is often seen in consumer markets because the capacity demand is small (less than one kVA) and the price is inexpensive.  

Devices such as laser printers, fax machines, copiers, vacuum cleaners, hair dryers, and projectors will damage or cause a UPS to malfunction because they tend to create instantaneous overcurrent.

Our Uninterruptible Power Supply (SANUPS) is an Online-UPS. It converts AC input to DC and then inverts back to AC to output a pure sine wave that protects your load devices. Even if a blackout happens, your load device will not get damaged. On the other hand, Line-interactive UPS and Offline UPS do not have a full capability to create a pure sine wave which means power fluctuations such as a blackout may damage your load device.   

You can find a backup runtime graph on our website. The higher the load %, the shorter the backup runtime. Please remember the backup time varies depending on the temperature, load device’s power factor, and age of the battery.

Yes, there is a bypass circuit in our UPS system for even greater reliability. UPS changes the mode from an online mode to a bypass mode when overcurrent happens. The change is instantaneous, and there will be no power down. The system will check if the load has no problem, and then changes the mode back to online mode. This mechanism works in the same way when overload happens. If the UPS is damaged by overcurrent or overload, the output will be stopped.

Hardwire connection type UPS systems require compatible cables. To find out the cable size, please check the user manual.

EPO stands for Emergency Power Off. UPS that include part number 011 are called Type-C, and they have an EPO interface. You can utilize this interface to control (e.g., send a shutdown signal) and communicate (e.g., send a serial signal) with the UPS from the remote device.

Single-Phase power refers to a two-wire Alternating Current (AC) power circuit. Typically there is one power wire and one neutral wire. Those two wires produce AC power similarly to riding a bicycle, two legs are a single-phase system delivering power to your bike. With this system, the power is delivered unevenly, with maximum power when the legs are horizontal and no power when legs are at top and bottom.

Three-Phase power refers to three wire Alternating Current (AC) power circuits. Typically, there are three (Phase A, Phase B, Phase C) power wires (120 degrees apart in each phase) and one neutral wire. Three-Phase systems produce power similarly to riding a bicycle, but with an imaginable third leg and third pedal. It can deliver power continuously to the bike instead of delivering power unevenly as Single-Phase does. The major advantage to a Three-Phase system is that it delivers large power more efficiently, reliably, and smoothly.

In the United States, SANYO DENKI is providing mainly Single-Phase UPS (Uninterruptible Power Supply) systems. Please contact Sales for Three-Phase UPS systems.

Yes, SANUPS Standalone Software is free. It is a free edition with limited features and only for use with Windows OS. The standalone version does not support a network connection. To unlock the full functionality, please purchase SANUPS Software (Windows ver. & Multi-OS Ver. available).

With customer’s feedback, we developed two shutdown products. Please select either SANUPS SOFTWARE or LAN Card to shut down a connected load.

①SANUPS SOFTWARE

When you purchase a UPS, it comes with SANUPS STANDALONE SOFTWARE. By installing this software on an administrator’s PC and connect it to the UPS via a serial cable, you can shut down your computer when the input power experiences a problem.

If you would like to shut down more than one device, please install SANUPS SOFTWARE on the administrator’s PC, and LAN Card on the UPS to enable all the target computing devices to communicate with the UPS. Please click the link below for more details. https://sanups.sanyodenki.us/product_cat/shutdown-tools/software/

②LAN Card

LAN Card can shut down a connected load via Local Area Network. Even if you are a remote place, you can still log-in to the control panel and see the UPS status, change the settings, and configure shutdown sequences. LAN Card has much more functionality than the SANUPS SOFTWARE, such as temperature and humidity monitoring. Please click the link below for more details. https://sanups.sanyodenki.us/product_cat/shutdown-tools/lan-card/

Our LAN Card can shut down the target device by logging in with SSH. Unlike a standard FTP connection, SSH communication encrypts all the information including passwords and ensures your security. SSH connections use a host key and a user key to establish a secure authenticated connection.

For Windows OS, though functions may be limited, you can shut down devices with password authentication only when a commercial SSH is installed in the target computer.  To configure this, please see the user guide. The user guide has multiple device shut-down information as well as SSH algorithm compatibility.

Supported Algorithm: https://ups.sanyodenki.us/support/solutions/articles/26000027463-appendix-a-j

LAN Card and SANUPS SOFTWARE STANDALONE cannot be used together.  If you are using the newest LAN Card and SANUPS SOFTWARE, the software has to be later than Ver.2.0.0.

If you have purchased a different version of software over the years, please change the LAN Card operation mode set to compatibility mode.

Yes, both LAN Card and SANUPS SOFTWARE can shut down virtual servers as well as data storage devices such as NetApp if they are capable of logging-in using SSH/Telnet. In this situation, the target OS does not need SANUPS SOFTWARE installed. For more detail, please see the product page here.  

For the new LAN Card (Part Number: LANIF011B-US and LANIF013-US), you can reset it by pressing the button that is on the front side of the LAN Card for a few seconds. The reset procedure will not impact the UPS.

If you forgot the IP address you assigned to the LAN Card and cannot access it, please initialize the LAN Card. To Initialize the LAN Card, you have to log in to the LAN Card by a serial cable. After you are connected, please follow the instructions here.  https://ups.sanyodenki.us/support/solutions/articles/26000027370-how-to-initialize-the-lan-interface-card

Our LAN Card comes with a serial cable that you can connect your PC and the UPS. If you were to use a third party cable, please make sure to use the appropriate cable. For detailed information, please see here.

Our UPS contains internal memory to record input power status, blackout duration, power restore time, load status, and UPS trouble, etc. You can check that information from the LAN Card. The event log will display as detailed code. Please locate a code with the code list in the user manual.

Simple Network Management Protocol (SNMP) is an application-layer protocol used to manage and monitor network devices and their functions. Also, our LAN Card supports an SNMP agent. An SNMP agent is a network-management software module that resides on a managed device. Our LAN Card supports agents using standard MIB RFC1628 & JemaMIB, and Expanded MIB is a private MIB. By using those agents, you can stop the UPS, display status, and monitor the UPS. There is no need to change the setting because our SNMP management system can communicate with all agents mentioned above. It is easy and user-friendly.

To set up a trap destination and community etc., please use our web management tool or a terminal tool. You may also refer to the instruction manual here: https://ups.sanyodenki.us/support/solutions/articles/26000027458-5-detailed-settings-with-the-web-management-tool

A management information base (MIB) is a database that manages the entities in a communication network and associated with the Simple Network Management Protocol (SNMP). Our LAN Card supports SNMP agent function. To download standard MIB data, please visit our website at https://sanups.sanyodenki.us/product/lan-card/ and click the “Software & Firmware” tab.

If you need a private MIB data, please contact us at (310) 783-5405 or e-mail us at sanups@sanyo-denki.com

UL is a voluntary standard that is certified by the nonprofit testing organization of Underwriters Laboratories Inc. founded in 1894. However, it became the de-facto standard in the United States, and this organization conducts the certification test of an electric appliance.

UL 1778 applies to Uninterruptible Power System (UPS). The primary function of the UPS for this Standard is to ensure continuity of an alternating power source. The Uninterruptible Power System also serve to improve the quality of the power source by keeping it within specified characteristics. This Standard applies to movable, stationary, fixed, and built-in UPS for distribution systems up to 600 V a.c. This Standard is intended to reduce the risk of fire, electric shock, or injury to persons from installed equipment, both as a single unit or as a system of interconnected units, subject to installing, operating, and maintaining the equipment in the manner prescribed by the manufacturer.

Our SANUPS Uninterruptible Power Supply systems for North America market are all UL1778 certified.

The International Electrotechnical Commission (IEC) is the world’s leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies.

IEC 62040-1 applies to movable, stationary, fixed or built-in UPS for use in low-voltage distribution systems and that are intended to be installed in an area accessible by an ordinary person or in a restricted access area as applicable, that deliver fixed frequency AC output voltage with port voltages not exceeding 1000 VAC or 1500 VDC and that include an energy storage device. It applies to pluggable and to permanently connected UPS, whether consisting of a system of interconnected units or of an independent group, subject to installing, operating and maintaining the UPS in the manner prescribed by the manufacturer.

IEC 62040-2 is a type test product standard for electromagnetic compatibility (EMC) and applies to movable, stationary, fixed or built-in, pluggable and permanently connected UPS for use in low-voltage distribution systems with an environment being either residential, commercial, light industrial or industrial, which deliver output voltage with port voltages not exceeding 1500 VDC or 1000 VAC and which include an energy storage device.

CE marking is a conformity certification with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). The CE marking is recognized worldwide and is the manufacturer’s declaration that the product meets the requirements of the applicable EC directives.

Electromagnetic compatibility (EMC) is the concept of enabling different electronics devices to operate without mutual interference – Electromagnetic Interference, EMI – when they are running close to each other.

EMC is now an integral part of any electronics design project. With standards now implemented and enforced across the world, Sanyo Denki’s UPS products have been tested to ensure it meets the relevant EMC standards. While this presents an additional challenge to the electronics design engineer, it is essential that good EMC practices are employed and the EMC performance of the product is sufficient to ensure it operates correctly under all reasonable scenarios.

The Federal Communications Commission (FCC) regulates interstate and international communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories. An independent U.S. government agency overseen by Congress, the commission is the United States’ primary authority for communications law, regulation, and technological innovation.

Nearly every electronics device sold inside the United States radiates unintentional emissions and must be reviewed to comply with the Code of Federal Regulations (CFR) Part 15 before it can be advertised or sold in the US market. CFR Part 15’s Subpart B deals with unintentional radiators such as computers that were not intended to produce radio waves. All Sanyo Denki’ SANUPS UPS systems comply with CFR15 Part 15 Sub-B Class-A.  

Voluntary Control Council for Interference by Information Technology Equipment – VCCI – is a membership organization with the purpose to suppress electromagnetic interference from ITE in Japan. VCCI started as a voluntary organization in 1985. VCCI was reconstituted as a legal entity “VCCI Council” in April 2009. The number of VCCI members is approximately 1,200 which is half Japanese companies and a half overseas companies. VCCI and FCC agreed to mutually accept test reports issued by accredited laboratories of the other country in February 2007 in the framework of Japan-US telecommunication MRA.

RoHS stands for Restriction of Hazardous Substances and impacts the entire electronics industry and many electrical products as well. The original RoHS, also known as Directive 2002/95/EC, originated in the European Union in 2002 and restricted the use of six hazardous materials found in electrical and electronic products. All applicable products in the EU market since July 1, 2006, must pass RoHS compliance. Directive 2011/65/EU was published in 2011 by the EU, which is known as RoHS-Recast or RoHS 2. RoHS 2 includes a CE-marking directive, with RoHS compliance now being required for CE marking of products.

JIS – Japanese Industrial Standards specifies the standards used for industrial activities in Japan. The Japanese Industrial Standards Committee coordinates the standardization process and publishes through the Japanese Standards Association. The objective of the Japanese Standards Association is “to educate the public regarding the standardization and unification of industrial standards, and thereby to contribute to the improvement of technology and the enhancement of production efficiency.”
