UPS Full Form

The full form of UPS is referred to as Uninterruptible Power Supply. It is a type of system to supply power by using a battery to maintain the power of the electronic machines in the event of a power surge or outage. 

UPS Full Form

Typically UPS power keeps computer systems and IT equipment running for several minutes after a power cut, enabling to save data in its memory and shut down the computer in an orderly manner. Many UPS systems now offer a software component that automates the backup and shut down procedures in case there’s a power cut while one is away from the computer.

  • Problems in the supply of power can cause:
  •  Equipment lockout, programs failure, and systems failures
  •  Data corruption
  •  Errors in data processing and transmission
  •  Errors in data transmission
  •  Errors in printing
  •  Hardware damage

Backup power is provided for a specific period depending on the size and technology of the UPS unit until the activated components can be properly shut down.

How do UPS works?

A UPS is electrical equipment that is fitted between the input power supply and a selected component of electronic equipment, known as “load”.

It has a battery to provide power in case of power failure. The duration of time that a load can be supported depends on the size of the UPS’s battery.

When power fails, the UPS’s batteries ensure a clean and steady supply, required to keep the load fully operational.

Types of UPS System

There are three types of UPS system:

  1. Stand-by UPS: Also referred to as Offline UPS, it delivers short-term, battery-sourced utility power during a power cut to hardware under normal conditions, through a direct AC connection. The standby unit and its inverter stay on hold until backup power is needed. This supply is mostly used to protect computers, modems, VoIP equipment, and other hardware.
  2. Online UPS: It supplies uninterrupted power that utilizes either a double or delta conversion technology. In this type of system, AC power travels to a rectifier, where it becomes DC power and then travels to the battery, and lastly an inverter. After inversion back to AC, the power is delivered to equipment. With this online UPS device process, computing equipment receives constant power. 
  3. Line-interactive UPS: It can regulate fluctuations in voltage by responding to high and low voltage conditions. Units also support systems during a power cut by converting battery power to AC flow for device delivery without battery drainage. 

Uses

UPS units are used to tackle various power problems, such as:

  • Surge and spikes
  • Under-voltage (brownout)
  • Over-voltage
  • Frequency variation
  • Switching transient
  • Harmonic distortion

Drawbacks

  • It is an expensive form used to maintain power supply. 
  • Some types of UPS contain a cooling fan, which creates a lot of noise.
  • Large corporate UPS devices consume more office space as it requires the attachment of many UPS batteries. Also these batteries last about 5-10 years, after which new cells must be purchased.
  • To keep the UPS batteries charged all time, the uninterruptible power supply (full form of UPS) system draws more power than required of the attached equipment.
