Isolation Transformer

Hey there,

I work on a 49 ft steel sailboat. We have an old isolation transformer on board when the boat was purchased rated for 240V 50 Amps of service. We want to replace it with a Victron product, however, according to the Victron Datasheet, the highest Amp rating is 32 Amps at 7000W. Would the isolation transformer work if we purchased two 32Amp isolation transformers and attached them in parallel?

Any suggestion on setup or product advice is greatly appreciated.

Thanks,

Olivia

Yes. You can connect identical isolation transformers in parallel. But any difference in secondary voltage can cause some circulating currents, during little or no load conditions.

Thanks for the response.

Would placing an auto transformer after the isolation transformer resolve this?
