ARBS 2600 (Automatic Redundant Battery Selector with Source Control and Monitoring)
The La Marche ARBS is a solid-state device that controls redundant power in engine starting switchgear applications. 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 with safety margin to spare.
The optional control circuitry allows for manual selection of sources and the ability to cycle them on a set schedule, if desired. This also includes alarm contacts to indicate the state of each source as well as a general fault alarm. The LCD display is used to show the voltages of both sources and any alarms present. The two green LEDs on the front provide a quick reference in regards to the source availability.
