This three-phase 400V to 230V<\/strong> transformer, available in standard or medical-use premises<\/strong> version, offers three key features: it provides substantial galvanic isolation, from 2,500 to 4,000 Volts depending on the version, it steps down the voltage from 400V to 230V, and it creates a neutral point at the output. For medical-use<\/strong> transformers, select the \"Medical\" feature in the product specifications.<\/p>\n

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.<\/p>\n

Transformers for medical-use premises comply with standard IEC 61558-2-15. These medical transformers have specific characteristics, which you will find in the technical details below.<\/p>\n

See also the three-phase 400V 400V transformer<\/strong>. If you require a three-phase transformer with adjustment taps or any other additional options, do not hesitate to send us a specific request<\/strong><\/a>.<\/p>\n

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.<\/p>","protected":false},"excerpt":{"rendered":"
