Application
Sealed-structure chargers designed for flooded lead-acid, sealed lead-acid, lithium, Ni-MH and Ni-Cd batteries. Intended for cycle and float charging of battery packs in electric bumper cars, sightseeing vehicles, patrol vehicles, forklifts, floor scrubbers, AGV, boats, golf carts and similar electric vehicles.

Protection Function

• Overtemperature protection: charging power reduces if internal temperature rises; charging stops and enters standby if ambient temperature exceeds 65℃ until temperature falls.
• Reverse-connection protection: internal circuit disables output when batteries are connected in reverse.
• No-load protection: no output when batteries are not connected.
• Short-circuit protection: internal shut-down on short circuit; charger restarts only after fault clearance and manual or power-cycle restart.
• Automatic shutdown when fully charged: charger detects full charge and stops charging automatically.
