The idea of a "voltage sensitive relay" (VSR) or "voltage controlled relay" (VCR) as they are sometimes known, is to simplify the installation, no connection is made to the vehicles alternator .
Simply connect this relay to the towing vehicles positive battery terminal (via a fuse!) and link to the leisure battery
The relay monitors the towing vehicles battery voltage and when it reaches 27.4VDC, the relay switches on and supplies charging current to the aux. circuits. When the engine is stopped and the voltage of the vehicles main battery drops below 25.6VDC the unit switches off.
Only 3 connections are required to the unit and as such it can be fitted in next to no time .
Supplied with detailed full colour instructions.
Please Note: Do not use on Euro V/VI engines, or engines with smart alternators or regenerative brakes. These newer systems do not give a constant voltage and are not suitable for a split charge relay.
