Frequently Asked Questions

How do I choose the right size (kVA) for my application?

Begin by calculating the total connected load in kVA, including any future expansion. Select a transformer with a rating equal to or slightly above that figure. The family offers ratings from 1.0 kVA to 100 kVA, so match your load to the nearest available rating.

What primary voltage options are available?

The family supports primary voltages of 120/240 V, 240 x 480 V, 277 V, 480 V, 600 V, and multi-tap configurations like 120/208/240/277 V. Choose the option that matches your incoming supply voltage.

What efficiency standard does this transformer meet?

DOE 2016 efficiency standards.

When did the DOE 2016 standard go into effect?

January 1, 2016.

What is the expected energy loss reduction?

15-18% on average for low voltage transformers.
