what is the operation of UPS ?
can any one answer me?
Answer Posted / shekar
ups is an interupted power supply unit.
Main supply will be directly given to the load and also to
the rectifiers which converts AC to DC to charge the
battery.when mains fail the charged battery will flow to
the invertor which converts DC to AC and will flow to the
loads.
