InPower introduces a 100 percent solid state Auxiliary Battery Switch/Electronic Battery Separator. The ABS Series Auxiliary Battery Switch is an ideal solution for charging an auxiliary battery and isolating it from the vehicle's chassis battery and alternator. This next generation patented technology is designed to replace outmoded diode-based battery isolators and the unreliable mechanical solenoid type battery separator/isolators.
The basic operating principles are simple. The auxiliary battery is charged from the chassis battery and alternator while the chassis battery is protected from auxiliary battery load discharge. As the ABS is bidirectional, a charging device such as a battery charger connected to the auxiliary battery can supply charging current to the chassis battery. The ABS accomplishes this through the voltage and current monitoring capabilities of its microprocessor controller. The proper time to transfer power between the chassis battery and the auxiliary battery is based on a proprietary algorithm that utilizes both battery voltage and current measurements. A "boost start" feature is provided that will allow the auxiliary battery to supply current to the chassis battery to aid engine starting. InPower's ABS Auxiliary Battery Switches are available in 100, 150, 175, and 200 amp models.
