UPS systems:
The full form of UPS is “Uninterruptable Power Supply”. They act as a backup power supply for computers. The powering capacity of UPS is usually measured in volt-ampere. A normal computer uses 200 VA and during interruptions or power fluctuations, it gets efficient power supply from UPS which provides up to 1,000 VA.
Types of UPS:
There are four primary types of UPS. They are as follows:
- Standby UPS
- Standby ferroresonant UPS
- Line-interactive UPS
- Double conversion online UPS
