ARBS (Automatic Redundant Battery Selector)

Standby generators occasionally fail to start due to weak or dead cranking batteries. The La Marche ARBS is a solid state device that controls redundant power for the engine starter. Our product is designed with high powered diodes to select the higher voltage of the two isolated DC power sources. The ARBS selects power from the best available battery while isolating the alternate battery bank. The special heat sink diode assembly is manufactured to handle high output requirements The diodes in the ARBS allows the starter motor cranking current to flow from the battery to the starter.
