Product description
Application:
The Power Pack is used to supply DC axillary supply to the Trip / Close coil of the Circuit breakers when AC input is not available. DC Power Pack with Battery Back Up is used as a power source for VCB panels in sub-stations where station battery supply is not available.
Function:
BPS Power Packs has three sections,
a) Regulated DC source:
During Mains on, SMPS type regulated terminates DC source to power aux. supply to the annunciator, indicting lamps, instruments,
b) DC-DC converter:
During the Mains Off condition, the DC-DC converter is activated which converts 12 V to 110/30/24 V as a backup supply.
c) Automatic battery charger:
During Mains On and when the battery needs charging, it charges the built-in 12 V SMF battery.
There are two sets of outputs of the DC Power Pack with Battery backup. One output is for stored energy and the other is for non-stored. Stored output can be used when the AC input is off. Non-stored output is available as long as AC input is present.
