Three to single phase medical transformers application

Three to single phase medical transformers are used to create electrical insulation protection between several circuits. This product is highly suitable for high rating single phase loads and current unbalance is reduced (in comparison to three phase transformers). It is produced with Wye connection including a neutral point (nevertheless, the neutral point is optional) and delivered with its control certificate.

Product description

Thanks to performant, reliability components and our know-how, we master three to single phase medical transformers according to your specific requirements.

Each product is individually controlled and each batch is delivered with its control report.

Coupling / Connection

According to the transformer power, using transformer terminal block with self-rising clamping plates or linergy passthrough terminal block to connect the transformers.

Wye/single phase connection with neutral point as standard coupling for three to single phase isolating transformers.
