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 13.3vdc, 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 12.8vdc 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. (No cable is supplied with the unit unless the "kit" is purchased)
Also available as a ready assembled kit with a 6 + 1 metre pre-assembled heavy duty wiring harness complete with twin fuses.
The kit is manufactured using 2 x midi fuse holders & 16mm2 / #6 AWG heavy duty extra flexible battery cable.
Switch on voltage 13.3vdc
Switch off voltage 12.8vdc
