Constant Run RV Transformers, 4kW 240v - 120v, Custom Made


These transformers have been specifically designed for converting UK 240v electric for 120v  American RVs.

People think it's 240v to 110v and use building site transformers and other such - many transformers are not designed for constant running and will over heat and risk causing fire. The US voltage needed is 120v not 110v.  Our transformers are specifically designed for us to the exact performance and need of an American RV - running air conditioning continuosly without overloading.

In all our fifth wheels we install a 4kW CTR transformer which is basically 16amps in, 32 amps out.

Please call Paul on 01638 515 700 for friendly advice about electrics or any fifth wheel advice you might need.
