POW-1-PA – Single Phase SCR/Thyristor Power Controller/Regulator for Single Phase Heater.
Libratherm offers a Single Phase Thyristor Power Controller for heating control of resistive or inductive loads. This phase angle controlled SCR Power Regulator accepts the user-selectable control signal of 0-5V, 0-10V, and 4-20mA or through the potentiometer, and hence, can be easily interfaced with DDC, PID, or PLC. The output voltage can be varied proportional to the input signal. The phase angle firing control technique ensures a smooth and gradual step-less voltage control across the heater load. The facility is also provided to adjust the soft rise or drop in the voltage across the load using on card Ramp Up and Ramp Down potentiometers. The maximum and minimum voltage output can also be adjusted. These Thyristor Power Pack Modules can be easily mounted on the standard 35mm DIN rail or on the base plate using 4 screws.
