What Is An UPS?

Introduction

UPS stands for an uninterruptible power supply or uninterruptible power source. It can be defined as an electrical assembly that works to provide power to your home/office when the main power fails. It makes use of battery and inverter to achieve this task. UPS is also used to prevent voltage peaks and to provide enough time to switch off the appliances properly. The first UPS power device was manufactured in 1950s.

How Does a UPS Work?

When power from main supply is cut off, the UPS will provide power stored in battery via inverter where the DC is converted to AC and then supplied to the appliances that are connected to UPS. When main power supply returns, UPS shuts down power supply and begins battery-recharging process.
