S.C.R. Power Controls

Flameless Electric Air Heaters: S.C.R. Power Controls Flameless Electric Air Heaters: S.C.R. Power Controls

These controls provide phase angle proportional control of our fast responding heaters. They are available in single and three-phase 240-volt configurations. Each unit comes complete with I 2 T Rectifier Fuses and a Voltage Limiting Adjustment.

The controls can be operated manually with the addition of the optional Manual Voltage Control, which allows one to vary voltage from zero to full voltage.

The S.C.R power control can be used with a 4-20mA temperature controller for closed loop operation.

The S.C.R power controls are also available in NEMA 1 Enclosures upon request.
