Frequently asked questions

Can I request a custom specification?

Send the input and output voltages, rating, frequency and mounting requirements for review. Availability is subject to the specific combination of requirements.

Are these dimensions fixed for every configuration?

These are reference dimensions. Voltage, winding type, terminals and construction may change the final size. Confirm dimensions against the approved drawing.

How do I confirm approvals and documents?

State the destination, required approvals and documentation in your inquiry. We will confirm availability and the applicable model and scope.
