what is the difference between ups & inverter
Answer Posted / sundaresan.m
UPS - (Un interupted power supply) It is used when power
shut down it will gives the power as same as 23o volts upto
the EB power comes .
INVERTER- It is device which converts the AC supply to DC
supply and stores in the battery when EB supply is on and
when EB power shut down it will convert again the DC power
to AC power from the battery to switch boards through the UPS.
