SCR's: Precise proportional control of resistance heating loads. SCR's provide reliable voltage control solutions for a wide varitity of heating applications.

Constant resistance heating loads can be controlled to tighter tolerance
High inrush heating loads can be brought on line slowly with a "soft start" or ramp up to voltage.

Payne offers features that make SCR's reliable for today's manufacturing enviroment.

• Large Specially engineered Heat sinks allow higher temperature tolerance.
• Surge Protection: "Vbo Clamping" protects semiconductors against transient voltages regardless of PIV ratings and without MOVs.
• Short Circuit Protection: factory-tested sub-cycle, "2 millisecond" current-limiting fuses protect the power semiconductors against short circuit damage.
