UPS and Its Functions
In this following article, we will explain you all about UPS and its functions along with other related aspects.
UPS also known as Uninterruptible Power Supply, is an electronic and hardware equipment which helps your computer device keep running in case of power/electricity drop.
Most commonly when we talk about a UPS, the first thing come in our mind is a power back up for a computer device.
The UPS basically is an emergency power system for a short period of time for your computer desktop device which allow you to save your current work or data and turn off your computer safely.
Please bear in mind, in here we are talking about a basic UPS for your computer.
Although, there are different variants of UPS, which provides backup for your computer or a group of computers for a long period of time depending on the number of batteries installed in it.

What is a UPS?
The UPS stands for Uninterruptible Power Supply also known as an Uninterruptible Power Source, Power Backup or Battery Backup.
In general, a UPS is a combination of a circuit board and a battery or set of batteries.
The UPS converts incoming AC voltage to DC voltage and backup your system when primary power of source is lost or when a power surge happens.
A UPS is generally used to protect hardware, Windows or software crash due to main power failure. Even in a little fluctuation, it prevents the sudden shutting down a machine.
It provides backup power at the time when your main power fails, drops or fluctuate from a level of power which a system required.
The number of batteries installed, size and design of a UPS determine that how long it will back up your computer or a group of computers.
Basic UPS comes in different wattage. Based on the manufacturers, you may find UPS in below VA and higher:
- 600 VA
- 625 VA
- 650 VA
- 800 VA
- 850 VA
- 1000 VA
Why we Need a UPS for a Computer?
The most common role of a UPS is to provide power backup when the main source of power fails. However, there are also few more advantages which a UPS does for us:
- Pass on requiring power at the time of voltage spike or overvoltage
- Protect from voltage surge
- Controlled instability of the main frequency
How a UPS Functions?
A UPS performs below functions:
- It absorbs small power surges
- Smooth out noisy power sources
- Continuously provides power to your machine during line sag
- It will provide us the time to shut down the computer during power outage without data loss
- Indicates red light with a beep when not getting the main power
- Alarms on certain error conditions
- Provide short-circuit protection
Hoping, the above information, gives you an overview that what is UPS and how it functions for your computer machine.
