A11N Draft


SANUPS A11N is the NEXT-GEN double conversion online uninterruptible power supply (UPS) that builds on the success of the A11J. Designed with high reliability and flexible scalability in mind, the SANUPS A11N offers exceptional efficiency and advanced features to ensure uninterrupted power supply to your mission-critical systems.

As industries continue to place greater importance on environmental sustainability, they are also becoming increasingly reliant on mission-critical systems.

In response to these trends, the SANUPS A11N was developed to provide a reliable and environmentally friendly power supply solution.




The SANUPS A11N’s use of three-level inverter technology in the DC/AC conversion circuit, combined with its CVCF (Constant Voltage Constant Frequency) technology, enables it to achieve an impressive a maximum efficiency of 95.1% (94% at rated time), which is the highest in the industry. This innovative design helps to significantly reduce running costs by minimizing power losses and reducing heat generation, while ensuring that the UPS operates at maximum efficiency, even during periods of high demand. As a result, the SANUPS A11N offers users unparalleled energy savings and lower operating costs over time.

In recent years, many types of control power supplies built into servers have gained the power factor correction function of the input current. It tends to raise the load power factor. In order to handle this situation, the new model has achieved a 0.9 output power factor. It allows the new model to supply sufficient power even when there is an increasingly high input power factor.

The system can operate on normal mode when the input voltage is -20% to +15% of the nominal input voltage while supplying sufficient output capacity (Max -40% to +15%). With I/O asynchronous mode, the output of 50/60 Hz can be supplied even with an input frequency in the range of 40 Hz to 120 Hz.



A11N is using modules for the battery and the power converter resulting in high maintainability. The modules use a plug-in method, so even if a malfunction occurs during parallel redundant operations, the power module can be replaced quickly while supplying inverter power, as a maintenance bypass circuit is provided as standard . This ensures high availability.


A11N has an LCD operation panel which can be removed from the uninterruptible power supply and placed anywhere you desire. The Operation panel lets you configure the uninterruptible power supply settings easily and quickly.

A11N comes with various battery management features. It can perform automatic battery self-tests to check for normality and connection, which guarantees dependable performance during power outages. Additionally, the A11N is equipped with battery life warnings, total battery operation time display, battery charging rate display, and backup time estimation display.

Along with its fortified components and advanced technology, the SANUPS A11N is produced in an ISO9001/14001 certified factory with strict quality control measures. These aspects contribute to the SANUPS A11N’s impressive product life cycle and one of the highest MTBF rates in the industry.

You only need to replace the battery packs of the UPS unit periodically. There’s no need to replace the fans or fuses. The UPS unit is expected to last for 10 years on average if it’s kept in an environment with a temperature of 30ºC.

Additionally, SANUPS A11N offers long-life batteries as standard (with an expected life of 5 years), and ultra-long-life batteries (with an expected life of 10 years) for reduced battery maintenance and to contribute to long product cycle.

Double Leak Proof

SANUPS superior double-sealed battery design prevents short circuits and important data loss.

Smooth Air Flow

SANUPS’s improved heat prevention design increases its efficiency and saves more electricity than the previous generation.

Coating Protection

SANUPS’s circuit boards are fully coated through soldering to prevent short-circuiting, caused by dust and insects. Our dust filters are also available as an option.

Auto Health Check

SANUPS periodically performs an automatic battery test for maintenance purposes and sends notifications to the host if an issue occurs.

Noise Reduction

SANUPS emits the lowest electrical noise possible preventing potential problems to the connected loads. The circuits are designed in the acoustic anechoic chamber.

Leak Proof Battery

A11N automatically checks the battery’s condition periodically and sends notifications to the host when a problem occurs. The auto health check-ups extend the battery life.

Wide Input Range

SANUPS A11N provides value to customers with a very wide input voltage window, extremely tight output voltage, and frequency regulation.

Over Current Protection

SANUPS stops excessive current when overcurrent occurs resulting in no voltage change to the utility power and related equipment.

Short Circuit Protection

SANUPS automatically disconnects the circuit in the event of overload or the short circuit, preventing damage to the network and equipment.

SANUPS Software


SANUPS SOFTWARE is a shutdown assistant. By installing it on the shutdown target computers, your mission-critical equipment can be safely shutdown ensuring system up-time, data integrity, and the ability to maintain business continuity. The application shutdown function even shuts down Microsoft office applications as well.

SANUPS SOFTWARE is innovative software because it also has the capability of a commander server*1 (LAN Card functionality) as well as uninterruptible power supply system monitoring for today’s complicated IT infrastructure.

*1 To use the software acts as a commander, please connect commander PC to uninterruptible power supply via serial cable.

*1 Shutdown target devices need to be powered by the same uninterruptible power supply that the commander PC is powered by.
