Features & Benefits

Unit disconnects non-critical loads when battery voltage falls below threshold, reconnects when battery is recharged.

Unit is auto-ranging: identifies whether system is 12V or 24V, and automatically establishes thresholds. One part number; two voltages. 250A at 85ºC.

Eliminates dead battery service calls and lost time. Extends battery life by preventing irreversible damage due to excessive discharge.

No action is required by vehicle operator to protect the batteries – unit automatically disconnects and reconnects, giving operator a warning one minute before disconnect. 250mA alarm signal can drive audible or visual systems or any large device via a relay. Optional manual override feature.

Can be mounted in harsh environments – sealed to IP67, with sealed Deutsch connector. Solid state reliability and resistance to vibration – replaces vulnerable conventional solenoids. Unit exceeds one million cycles and is protected from over-temperature, overcurrent, overvoltage, and under-voltage. Minimal draw on battery (only 1mA standby).

Protects vulnerable onboard electronics such as GPS, phone, computer. Solid-state switching creates less electrical noise and interference, and eliminates spikes.
