Voltage Sensing Relay 12volt 60amp ADR-ARB546
This allows the charging of two separate battery banks from a single alternator without the risk of flattening the main vehicle battery.
The relay is By sensing the main battery bank voltage, the device will only connect the secondary bank to the source when the first is fully charged (showing 13.3V or over) and will cut out if the main bank falls below 12.8V. This ensures that the secondary bank can never drain the main bank.
Suitable for use with solar panels, wind power and alternators it can handle a charging current of up to 140A. Zero voltage drop. No moving parts and fully encapsulated electronics make it suitable for marine use.
Measures 68mm x 54mm x 68mm and suitable for surface mounting with cables entering from the rear. An LED indicates when the secondary bank is connected.
To use, connect the stud marked with red to the positive terminal of your main or priority battery bank (the one connected to the charge source), and the other stud to the positive of your secondary bank. Finally connect the small black cable to the common negative. Good sound connections and adequate cables sizes are important for correct voltage sensing.
