UPS is not DC it's AC....this equipment usually to support
Control system such as Computer Sentral Control....this
equipment is supplied by battery which the battery is DC
source.....and convert by inverter inside UPS to AC source
to supply the emergency equipment...
emergency equipmen is equipment where may not interrupt
even the main source is blackout....
if you mean DC source this could be battery
charger....battery charger ussualy used to operating
controoler....such as PLC, also some electrical equipment
is needed DC source...such as Circuit breaker, ACB(Air
Circuit Breaker) motor inside the breaker is using DC source
