Online UPS - 24/7 Critical Power Backup
An Online UPS is a device which provides backup power when there is a power shortage. It may seem to be similar to an inverter but practically it is more complicated system designed to switch to battery power when there is a power failure.
It uses a double conversion technology where the Input AC power is rectified to DC then DC is again converted to AC. The system is connected to a power bank which is usually a sealed maintenance battery or lead acid battery. The switching time from raw power to battery mode is usually maintained within 10 micro seconds.
Depending upon the load and required battery backup the Online UPS can be customized. The Capacity of the UPS is generally represented by KVA and battery VDC depends upon the capacity and backup that is required.
Online UPS is of two types:
- Low Frequency Online UPS
- High Frequency Online UPS
