TYPES AVAILABLE
Float cum Boost
ƒ
Single rectifier circuit.
ƒ
Operation in either Float mode to feed load and
trickle charge battery or in boost mode to charge
battery.
Float and Float cum boost charger
ƒ
Two independent rectifier circuits.
ƒ
Float charger feeds load and Float cum Boost charger charges battery.
ƒ
Float cum boost charger can function as Float charger also.
Dual Float cum boost charger with one battery bank
ƒ
Two independent rectifier circuits.
ƒ
Each capable of operating inn either mode. Hence redundancy available.
ƒ
Simultaneous operation of both chargers in boost mode is not possible.
