Unit is auto-ranging: identifies whether system is 12V or 24V,  
and automatically establishes thresholds. One part number;  
two voltages.  
Eliminates dead battery service calls and lost time by  
extending battery life and preventing irreversible damage  
due to excessive discharge.

PART NUMBER  
DESCRIPTION  
No action is required by vehicle operator to protect the  
batteries – unit automatically disconnects and reconnects,  
giving operator a warning one minute before disconnect.  
200mA alarm signal can drive audible or visual systems or any  
large device via a relay. Optional manual override feature.

Electronics are sealed to IP67, see Installation Instructions  
IF-162 for mounting and wiring details. Solid state reliability  
and resistance to vibration – replaces vulnerable conventional  
solenoids. Unit exceeds one million cycles and is protected  
from overcurrent, overvoltage, and under-voltage. Minimal  
draw on battery (only 1mA standby).
