This Tri-Mono 400V – 230V transformer, with its specific coupling, offers three key features: it converts a three-phase primary network into a single-phase network while limiting supply network imbalance; it provides substantial galvanic isolation, from 3,000 to 4,500 Volts depending on the version; and it steps down the voltage to 230V single-phase.

This type of product is particularly suited for power ratings generally above 1 kVA but below a few tens of kVA. It is available in bare or enclosed versions, selectable via the Protection (IP) menu.

If you require a three-phase to single-phase transformer with adjustment taps or any other additional options, do not hesitate to send us a specific request.

As this product has no adjustment taps, we have designed it to be tolerant to over-excitation. This tolerance has its limits, so do not hesitate to contact us if your network voltage is high, if harmonics are present, or for any advice on a specific installation.
