## Understanding the Difference Between Single-Phase and Three-Phase Power Transmission

When it comes to transmitting electricity, we often encounter two primary methods: single-phase and three-phase alternating current. Single-phase power is commonly associated with household appliances and small-scale electronics, as it efficiently delivers relatively modest electrical loads. In contrast, three-phase AC combines three single-phase currents in evenly spaced intervals and finds its application in powering large-scale […]

## An Easy Guide To Selecting UPS: Voltage

In this blog, it discusses the voltages and other parameters that you should know for selecting the right UPS. Input/Output Voltage The voltage input to the UPS and the voltage output from the UPS are basically the same voltage. Input/Output Types There are two types of input/output: [outlet] and [terminal block]. Single Phase and Three […]

## An Easy Guide To Selecting UPS: Selection Methods

UPS Capacity Selection by kVA or by kW When selecting a UPS capacity, the selection method differs depending on whether it is selected by kVA or by kW. When selecting in kVA: Select a UPS with a capacity that is greater than the total kVA of the load capacity (power consumption of the load equipment) […]

## An Easy Guide To Selecting UPS: Active Power

Vol.2: Active Power 1. What are Apparent Power and Active Power? There are two types of capacity notation. Apparent power (kVA): Total power that is available to run  Active power (kW): Power that actually does work Since there is a deviation between the flow of voltage and current, the power that can theoretically be produced […]

## An Easy Guide To Selecting UPS: Capacity

Vol.1 – Introduction to Capacity In this tutorial series, you can learn the easy steps on how to select UPS for your equipment or facility. First, let’s go over on basics with capacity. 1. What information is required when selecting a UPS? Capacity (kVA, kW), load equipment (model/power consumption) Input/output voltage (V), number of phases […]

## What Are the Methods of Supplying Power?

How a Double Conversion Online UPS Works There are various types of UPS products. There are four main methods to supply power: passive standby topology, hybrid topology, double-conversion online topology, and parallel processing.   1. Passive standby topology This method has less power conversion loss. As there is a slight momentary interruption during a power […]

## Types Of Batteries Used In UPS

There are several types of storage batteries used in UPSs, but lead-acid batteries and lithium-ion batteries are the most common. Lead-acid batteries are also used in automobile batteries. The Initial cost of installation can be kept low, but the disadvantage is that they must be replaced in about 3 to 5 years. On the other […]

## How does an UPS continue to supply electricity in a power outage?

The basics of UPS How does a UPS continue to supply the electricity in the event of a power outage? The structure is actually quite simple. Imagine an extension cord that you often use in your office or home. It has multiple plugs at the end of a cord that is connected to the power […]

## Difference between emergency generators and UPS

What is the difference between emergency generators and UPS? Both emergency generators and uninterrupted power supplies (UPS) are designed to back up a system when the original power source fails; however, there is a major distinction between the two.   1. Generators Generators installed at private corporations and public facilities can generate power for long […]
