Power Terminal Torque: 10 to 15 Ft. Lbs.
The ABS3 uses InPower’s proven patented solid-state contactor technology, incorporating sophisticated microprocessor algorithms to monitor over-current and under-voltage sensing.
The auxiliary battery is charged from the chassis battery and alternator, while the chassis battery is protected from auxiliary battery load discharge. Since the ABS2 is bidirectional, a charging device (such as a battery charger or genset) connected to the auxiliary battery can also supply charging current to the chassis battery when needed. A “boost start” feature allows both the auxiliary and chassis batteries to supply current to aid engine starting.
InPower’s ABS3 Auxiliary Battery Switches are available in 100, 150, 175 and 200 amp models. To properly size your ABS3, first determine how much extra current is available from the chassis alternator. This is the maximum alternator output current less the minimum chassis load current. The difference is the maximum available auxiliary battery charging current. Select an ABS3 model with a capacity greater than this current.
