How capacity is chosen

The rating follows the load: the sum of the connected load in kVA, adjusted for starting current, power factor and any spare capacity the client wants to carry. Selecting on nominal load alone is the most common cause of a regulator that trips when a motor starts.

How the correction range sets the cost

A regulator designed to correct a wide input swing needs a larger regulating transformer and a more capable servo or static stage than one correcting a narrow band. The measured voltage range at the site therefore drives the price more than the kVA rating does.

Type

Servo-motor regulators for wide correction range and larger ratings

Static or electronic regulators for faster response at lower ratings

Single or three phase depending on the load

What to send us
