24V 100A Dual Smart Battery Isolator Voltage Sensitive Relay Protection VSR Split Charge For Car RV's Boat Marine Camper Truck
Compatible:
Widely used in cars, boats, camper vans, marine, trucks.
Details and features:
Voltage Sensitive Relays (VSRs) allow two batteries to be charged simultaneously.
When the engine starts and the starter battery reaches 26.6 volts, the VSR engages, allowing both battery packs (starting and house) to charge at the same time.
When the voltage drops below 25.6 volts (e.g. when the motor stops), the VSR disengages and the battery is separated.
The system eliminates the possibility of depleting the starter battery and protects sensitive electronics powered by household batteries from harmful engine starting spikes.
The advantages of mounting a VSR over conventional loads (diode isolators), easy 3-wire connection to the battery, no need to bypass existing alternator wiring, VSR has no voltage drop, and conventional diode insulators have a minimum voltage drop of 0.6 volts.
Small size, no large heat sink cost-effective, solution, quality products, affordable price.
