20Amp S Type 12v TEC2M Self Switching Dual-Charge Relay
See our 20Amp TEC2M Dual-Charge Relay
Our Part No. ETR03
Manufacturers Part No. TEC2M
This relay will convert a 12v supply to supply a 12S (‘S’ Type) socket
Easy to wire as pin numbers are marked on the unit
This relay automatically senses the condition of the towing vehicles alternator and diverts some of the current charging it’s battery to the caravans battery or fridge as well.
This happens automatically when sensors trigger a split charge relay at a set voltage.
This does not require a separate lead from the ignition switch as the switch in the relay is automatic.
It is important to use cables with sufficient stranding to prevent voltage drop as this can stop the relay from functioning.
Cable that has a minimum stranding of 35/0.3 (2.5 sq. mm) should be suitable for the 12v feed from the battery to the relay.
Cable with a minimum stranding of 16/0.2 (0.5 sq. mm) should be enough for the earth.
