pls help me identify this 120/240 shore pwr converter

[caffel]

I need to slightly modify the circuits for this unit which was added when our 120 v American yacht went to Europe.
Can anyone tell me who made it so I can find manuals or circuit diagram?

Thanks,

It says right on it that it’s made by Omeca? Don’t see a type ATR in the current catalog, but website has contact information.

OMECA - Catálogos

Or, what kind of changes do you want to make? It’s an autotransformer, there isn’t much specific to different ones.

Thank you.
Google and I got tangled up with 'Omega'.
The task is to use our Westerbeke Genny (120 v, 10 KVA) to power a dive compressor (240 v single phase 3 Hp).
Initially, using a superficial reading of the Westerbeke, the owner thought that getting 240 out of the Genny would be easy.
Luckily, I spoke to an experienced Westerbeke tech who suggested that while this was possible, the changeover back and forth from 120 output to 240 output for this Genny wasn't recommended. (an internal layer, lugs and jumpers that are pre-wired at the factory must be disconnected and reconfigured).
Next option; the transformer, is right there and unneeded for shore power.
My (now forming) plan is to label the wires and then disconnect the transformer from the rest of the boat, the buss and switches on the device (reusing only the fuses).
Then supply 120 V from the output of boat's Genny AC circuit breaker using a 10 Ga wire to the 120 v side of the transformer. And connect the the dive compressor to the 240 side.
Having said all of that, I'm currently focused on making my peace with auto transformer circuits and wishing I had a double breaker for the 240 output and/or an appropriate switch to be placed on the compressor.

Thanks again for the tip. Further advice welcome.
