Automatic Voltage Regulator
and Line Conditioner
120/240V single phase 50/60Hz
19kVA thru 57kVA, variable transformer-type
The WHR Series is an extensive line of STABILINE® Voltage Regulators offered by Superior Electric. This line of regulators includes units for use on all AC power systems, up to 660 volt, currently in use throughout the world. An extensive range of standard sizes, features and options is included. Made in USA
WHR Series STABILINE Voltage Regulators maintain constant voltage to your equipment, even when the input voltage and system load vary widely.
All electronic and electrical equipment is designed to operate at a particular nominal voltage. If the actual voltage becomes too high or too low, equipment malfunction or failure will occur. WHR Series Voltage Regulators are a cost effective way of eliminating these problems. For a complete discussion of these regulators and how they solve many power system problems read the excellent factory product brochure at this link.

1Unit will operate below -20% input Voltage but output Voltage will be less than 100%.
2Input breaker should be selected to withstand transformer inrush current of 6X to 10X full load current
for several cycles without tripping. If breaker has a low instantaneous trip region it could trip when the
regulator is first turned on. Contact NoOutage for assistance evaluating proposed input breaker.

What size WHR Series STABILINE Voltage Regulator is Needed?
Regulator sizing is based on the maximum load initially planned, plus a small amount for future expansion (about 10% to 25%), and occasionally some derating for special conditions. The load may be stated in current (Amperes) or kVA. The rating charts list both.
Several methods to determine the size regulator required are outlined in the factory product brochure beginning on page 16. If the regulator will be installed at the service entrance to carry the full electric service load then the service rating in Amps can usually be used as the maximum load. So, for a typical North American single phase 120/240V 200A service the rating would need to be 200A x 240V = 48,000VA or 48kVA. However, in many cases the service is way oversized for the actual building loads and an evaluation by an electrician may be able to show that a smaller capacity regulator would be sufficient. NoOutage can also provide technical assistance sizing the regulator.
When you are ready to place an order we recommend requesting a firm up-to-date quote with any additional options you may want. These regulators are built to order and therefore are not cancelable and cannot be returned.
