This single-phase safety isolation transformer, with multi-voltage 230V and 400V primary, adapts to all standard electrical networks. Available in a wide range of power ratings, from a few tens of VA to several kVA. It is generally used in its bare version (IP00) and installed inside a machine or cabinet.

With its 4,500V galvanic isolation between primary and secondary, it will perfectly isolate your installations and ensure the safety of people.

Whether you have a 230V or 400V network, you simply need to choose the appropriate connection on the transformer primary.

This product, with its 24V secondary voltage, meets the requirements of standard IEC 61558-2-6 for safety transformers: reinforced insulation and a secondary voltage strictly below 45V.

Le Cosinus can of course supply other safety transformers: 12V, 48V or any other custom voltage, as well as enclosed versions.
