This single-phase isolation transformer, designed for circuit separation<\/strong> with multi-voltage 230V and 400V primary, fitted with \u00b115V adjustment taps, adapts to all standard electrical networks. Available in a wide range of power ratings, from a few tens of VA to several kVA, and in bare IP00 or enclosed IP2x versions.<\/p>\n

With its substantial 4,500V galvanic isolation between primary and secondary, it will perfectly isolate your installations.<\/p>\n

Whether you have a 230V or 400V network, whether these networks are slightly low or slightly high in voltage, you can choose the appropriate connection on the transformer primary during installation.<\/p>\n

Choosing the correct adjustment tap has two important advantages: obtaining the closest possible nominal voltage at the secondary, and avoiding over-excitation of the transformer in case of excessive network voltage. Over-excitation would result in transformer overheating and excessive electrical consumption through iron losses.<\/p>\n
