Transformer Size Calculator

When sizing a transformer, you need to know the kilovolt-amps (KVA) that your machine requires. This tool will allow you calculate the KVA that you need.

This tool only evaluates common voltages for North America (ie. 24v, 120v, 208v, 240v, 480v, and 600v). If you have a Eurpoean voltage or something else that is uncommon here then give us a call.
