Battery Charger of Auxiliary Battery
The charger automatically starts when the appropriate qualified power is connected, either from
grid, generator. With multiple charging stages (soft start-bulk absorption float-recycle),
LMP1218-PWM is designed to fully charge battery quickly. To guarantee the optimal charging for
batteries of different states, the LMP1218-PWM features Microprocessor-controlled charging
algorithm. The Float and Recycle charging programs guarantees the battery being charged
properly upon being connected for a longer period.
