SCR Control Panels
This fully proportional SCR system with PID temperature control is recommended for industrial heating applications which must accommodate material flow changes and provide the highest degree of accuracy for outlet temperature control.
Standard Features
PID self-tuning temperature controller (adjustable process temperature, with thermocouple input)
Heatrex three-phase, zero cross-fired, SCR power controllers
NEMA 12 painted steel enclosure, wall mount unless otherwise noted
Over temperature controller (adjustable temperature limit with thermocouple input)
Door interlock disconnect switch
Manual reset pushbutton with built-in pilot light (red) for visual “OVER TEMPERATURE” alarm
Selector switch – ON/OFF with built-in pilot light (green) for “POWER ON” indication
Control power transformer
Safety contactors
Circuit fusing
Ventilating fan and filter when required
