Power controls
Solid state controls with thousands of uses, for electric ovens and process heating, from 10 amps to 1650 amps, single and three phase, 120 VAC to 600 VAC.
Solid state power controls since 1959
Payne Engineering is one of the oldest manufacturers of SCR power controls in the world. We control power to electric heat from 10 to 1650 amps, single and three phase, 120 to 600 VAC, and start three phase AC motors with solid state starters.
Phase angle control
Zero fired control
Two product lines
Motor controls
Solid state motor starters built on over 30 years’ experience in demanding industrial applications, for reliable starting of three phase AC motors.

Three pillars of protection
Continuous investment of research time and engineering resources in power semiconductor protection gives Payne controls a level of reliability unmatched by other solid state controls.
“2 ms” fuses
Selected by strict criteria for clearing time and total energy let-through, they protect power semiconductors against short circuits.
TIP 202: short circuit protectionProprietary heatsinks
Heatsink designs that cool by natural convection, with no fans and no thermal degrading.
TIP 203: keeping SCR controls coolVoltage breakover clamping
Protects power semiconductors against transient voltage spikes, independent of PIV ratings.
TIP 201: transient voltage protection
Match the control to the load
Recommended controls by load type. The power control application guide adds line power and load configurations.
Constant resistance elements
Nichrome, Kanthal, Calrod. Resistance nominally constant, less than 50% change versus temperature.
Variable resistance elements
Quartz tubes, T-3 lamps, some infrared panels. A high hot-to-cold resistance ratio causes high inrush currents when elements are cold.
Silicon carbide elements
“Glo-Bar”, direct coupled. Resistance increases as elements age.
Transformer coupled loads
Heating elements driven from the secondary winding of a transformer: an inductive load with initial current inrush.
Inductive or resistive DC loads
Magnets, fields, electrolytic cells.
Technical library
Technical publications on the how, what and why of solid state power controls.
Built in West Virginia
Founded in Princeton, New Jersey in 1959, Payne Engineering moved to Charleston, West Virginia in 1961 and in 1966 to its present 65 acre site on I-64, midway between Charleston and Huntington. The site sits in the rolling hills of Teays Valley.
Installation, setup and troubleshooting help for every Payne product comes directly from the factory engineering staff, at no charge. You talk with a real person.
