This three-phase 230V - 400V transformer offers three key features: it provides substantial galvanic isolation of 3,000 Volts, it steps up the voltage of a three-phase network from 230V to 400V, and it creates a neutral point at the output.

Available in a wide range of power ratings, up to several hundred kVA, it is generally supplied in an enclosed version. You can also select the bare version using the Protection (IP) menu.

This product is typically used in industrial environments connected to a 230V three-phase network instead of the standard 400V.

If you require a three-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.
