Click on the Image to Enlarge

Voltage controlled (VSR - Intelligent) 30 Amp fridge and auxiliary battery split-charge relay for caravan/motorhome or trailer.

Voltage Sensing Relay - full intelligent control

Complete with instructions.

Easy to fit.

Suitable for 12v vehicles only.

The relay will provide two switched circuit outputs, (each 15 Amp rating), to be used conventionally, i.e. one for auxillary battery charging and the other to run a 12vdc fridge.

In addition a non- switched 12v feed is also provided to connect to Pin 4 of the 12S socket.

The idea of a voltage sensing  relay (VSR)  is to simplify the installation, no connection is made to the vehicles alternator or indeed its wiring system at all.

Simply connect this relay directly to the towing vehicles positive battery terminal and link to the appropriate pins in the grey 12S socket, thats it!

The relay monitors the towing vehicles battery voltage and when it reaches a pre set level, the relay switches on and supplies charging current to the aux. battery.

Only 6 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).

We also offer this unit as a complete kit with all cabling/fuses etc in our eBay shop

We also offer a 140Amp voltage sensing unit also, see our eBay shop for details
