Product Dimensions (mm) - H 45 x W 25 x D 40
Designed to protect the vehicle’s battery from accidental discharge when the vehicle is connected to the caravan electrics via the 12S (grey) plug and socket.
It does this by monitoring the battery voltage level and automatically detecting the change when the alternator is running.
It also compensates for the surge in current when the caravan fridge switches on so there is no need to worry about the unit switching off prematurely.
When the alternator begins to charge the battery, the voltage is detected by the Voltage sensitive relay and the relay switches on.
The voltage drops when the alternator stops charging, at which point the relays switch off.
The relays switch on at 13.5 volts and off at 13.2 volts, this is the normal operating voltages for a car battery
