About this calculator

Estimate required buck or boost voltage, winding current, and transformed VA for a supported low-voltage correction.

Method and assumptions

Required correction voltage = desired load voltage − available line voltage. Winding current = load VA ÷ desired load voltage. Transformed VA = correction voltage × winding current.

Confirm the actual connection and rating from the manufacturer diagram.
