FAQ

How do I select between the 230V and 400V primary inputs?

You need to connect your input power lines to the appropriate terminals on the primary side of the transformer. The terminal block is typically marked. For 230V, you would use terminals 0 and 230. For 400V, you would use terminals 0 and 400. Always consult the wiring diagram for this specific model before making any connections.

No, this transformer is designed to provide either 115V or 230V on the secondary side, not both at the same time. The output voltage is determined by how the secondary windings are connected. This configuration must be set before operation.

This is an open-style transformer (IP00) intended for installation inside a protective enclosure, such as a control cabinet. The terminals are exposed, and it does not offer protection against dust or water ingress. It must be mounted in an enclosure that provides the required environmental protection.
