The perfect solution for managing your vehicle's auxiliary battery system.
InPower's ABS Series Auxiliary Battery Switches charge and isolate an auxiliary battery from the vehicle's chassis battery and alternator.
InPower's ABS Series Auxiliary Battery Switches are an Ideal solution for charging and isolating an auxiliary battery from a vehicle's chassis battery and alternator. These products are designed to replace outmoded battery Isolators and unreliable mechanical battery separators.
Battery Isolators are simply high current diodes mounted to a large heat sink. Since all of the alternator's output current must pass through these diodes, as much as 8% of the alternator's energy is wasted to heat. With high current alternators, battery diode isolators are just not practical.
Battery Separators are high current solenoids that connect the chassis battery and alternator to the auxiliary battery. Typically, when the chassis battery voltage reaches 13.5 volts, the solenoid is closed. When this voltage drops to 12.8 volts, the solenoid is opened. Even with switching time delays, high Inrush currents and mechanical cycling combine to make mechanical solenoids an unreliable solution.
InPower's ABS Series Auxiliary Battery Switch is the next generation technology for charging and isolating an auxiliary battery from a vehicle's chassis battery and alternator. The ABS uses InPower's proven Patent Pending solid-state contactor technology incorporating sophisticated microprocessor algorithms that include over-current and under-voltage sensing.
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. This allows loads to be powered from the auxiliary battery without the risk of depleting energy from the chassis battery to the point that it cannot restart the engine. InPower's ABS Series auxiliary battery switches are bidirectional in that they can pass current from the chassis battery/alternator to the auxiliary battery and they can also pass current from the auxiliary battery to the chassis battery to provide a boost start to aid engine starting. The ABS-U Series are unidirectional and only pass current from the chassis battery/alternator to the auxiliary battery. The auxiliary battery switch products are available in 100, 150, 175 and 200 amp models.
