2.2.2.
Battery(stored)
Mode
UPS runs on battery mode when the mains voltage is bad.Battery Voltage is boosted for the
sufficient Dc bus voltage.
2.2.3.
Bypass
Mode
In an overload condition, or if there is a problem with the double conversion, the loads are fed by
the bypass line.
UPS switches to AC supply from inverter for that by static switches. Inverter must be
synchronized with the mains supply for these transitions to be seamless.This transitions might
take 15 ms depending on the type of load if inverter output is not synchronized with the mains.
2.2.4.
Auto
Restart
Mode
UPS supplies its critical loads up to end of discharge voltage level due to any mains failure. UPS
feeds critical loads untill end of battery discharge voltage level caused by any mains failure. Ups
will operate until batteries charging process completing after that will be switched off. UPS can
operate by itself in specified time after mains turned back to normal mode. In this case, UPS keeps
operating proper as long as UPS voltage being in accordance criterias. For Challenger Series UPS,
this feature is not activated as factory initial setups.
