Generally in AC we consider voltage, frequency and phase
sequence for parallel operation ... Can we parallel two DC
battery chargers? If yes, then what precaution to be taken
when we parallel two DC power?
Answer Posted / vinod
DC battery charger is feeding the float& DC load curent,
when AC fails battery will feed the DC,if charger fails
another charger can put in service.DC battery chargers not
required to parallel.(ie. battery having C10 capacity 100
AH or more)
