See how a 504V to 480V 3-phase delta buck-boost transformer corrects voltage and how to select the proper model.
Choosing a 504V to 480V transformer
Choose an available phase and load current to see a buyable exact-match unit for 504V to 480V correction. Current stock or lead time is shown with the result.
This voltage pair is used when the measured supply is near 504V and the connected equipment requires 480V. Confirm both values at the installation before choosing a transformer.
