240V to 277V Buck-Boost Transformer — Step-up, Single Phase
See how a 240V to 277V single phase buck-boost transformer corrects voltage and how to select the proper model.
Choosing a 240V to 277V transformer
Choose an available phase and load current to see a buyable exact-match unit for 240V to 277V correction. Current stock or lead time is shown with the result.
This voltage pair is used when the measured supply is near 240V and the connected equipment requires 277V. Confirm both values at the installation before choosing a transformer.
