It is a secondary battery it stores enough power as in case of yr emergency lamps and utilise it later.

UPS is for the purpose to give un-interruptible power

supply. This stores the energy in the form of DC by the

controlled rectifier (AC - DC converter) and discharge the

energy in the form of controlled AC by inverter (DC - AC

converter) so as to provide continuous power supply. Here

the back up is derived based on the requirement.

types:

1. Online Double convertion UPS (Normal High capacity UPS)

2. Online Delta convertion UPS (New technology offline

using buck boost Transformers)

3. Offline UPS (economical UPS medium capacity UPS 3 -

30KVA also available in higher capacity)

4. Line Interactive UPS (lower capacity UPS 300VA - max5KVA

output will be Squasi Sinewave).

UPS are used in home, medical, IT and industrial where the

critical load is used.
