Battery Management

BATTERY ISOLATORS

Designed for vehicles and equipment with multiple batteries - one for starting the engine and another for powering accessories Prevents a battery with a higher charge from draining into a battery with a lower charge Allows both batteries to be charged simultaneously from one source For use in 12-36VDC negative ground systems Electronic components are embedded for protection from contamination and vibration Integral heat sink provides efficient heat dissipation

CHARGE MATE AUTOMATIC BATTERY RELAY

The Charge Mate series connects both batteries during charging and keeps them isolated when discharging. The Charge Mate is especially practical for small systems. Inrush (250ms): 2000A Switch on delay: 5 sec Switch off voltage: < 12.75V (12V) or <25.5V (24V)
