Battery voltage monitor for 12 V applications. Automatic cut-off at low voltage protects the vehicle battery.
Dometic CoolPower M 50U is a universal voltage monitor. It makes sure you won’t have any problems, even if you forget to disconnect your cooling box or other 12 V appliance after parking the car or boat. When the battery voltage drops, the unit automatically switches the appliance off and back on again when the voltage returns to normal.
