Victron Autotransformer step down 240v to 120v

Hi,

I want to use the autotransformer to step 250vac down to a single 120vac.

To Run a 30 amp U.S. Rv from a U.K. 240v shoreline


I am not concerned with the 50/60 Hz issue , theres nothing onboard that cant cope with the 50Hz.


The manual shows various configerations except the one i want to do.. They show using it as a split phase. I only want a single 120v phase. out.


Can anyone confirm the Correct wiring for this arragnment please

It's all in the manual, when using only one leg of the 120V side, you can use 35A max.

Thankyou.

maximum input will be 240V @ 16A so outputting at 120Vac ( 32 amp ) i am within spec i am sure.

The autotransformer is a LOT lighter , hence my choosing of that product.

It will be being installed by an electrician , not myself but i wanted to make sure what i bought him will do the job.


Manythanks again, as i suspected just wire using 1 leg of the 120. ( it was only drawn using the 2 legs )
