o POWER PLANT MANAGES DC POWER REQUIREMENTS OF EQPTs AT THE SITE.o IT PROVIDES FAIL SAFE -48 V DC SUPPLY FOR ALL EQPTs. o SUB UNITS OF POWER PLANTS ARE :

BATTERY BANK PSU ALARM PANEL MCB FRAME BUS BAR FUSE

o POWER PLANT IS CONNECTED TO 48 V BATTERY BANK AS WELL AS 230 V AC POWER SUPPLY FROM ACDB.

o WHEN AC MAINS IS AVAILABLE, POWER SUPPLY UNIT CONVERTS IT TO 48 V DC.o +48 V FROM PSU IS TERMINATED TO COMMON BUS BAR WHICH IS FURTHER CONNECTED TO

IGB FOR GROUNDING.o –48 V SUPPLY IS CONNECTED TO FUSE TERMINAL WHICH IS ALSO CONNECTED TO –ve O/P

TERMINAL OF BATTERY BANK. o WHEN AC IS AVAILABLE, PSU PROVIDES DC SUPPLY TO EQPT AS WELL AS TO BATTERY BANK FOR

CHARGING.


o WHEN AC MAINS FAILS OR GOES UNDER/OVER VOLTAGE, BATTERY BANK SUPPLIES 48 V DC TO ALL EQPTs.
