POW-2-PA-20A – Two Phase SCR Power Regulator for Two Phase Heater.
Libratherm offers Two-Phase SCR Power Regulator Model POW-2-PA for power control of resistive or inductive heating loads. This Phase Angle Controlled Thyristor Power Controller accepts the user-selectable DC control signal of 0-5V, 0-10V, and 4-20mA and hence can be easily interfaced with DDC, PID, or PLC. For manual control, an external potentiometer can also be used. The output voltage can be gradually varied proportionally to the input signal. The built-in back to back connected SCR can control single-phase or a two-phase load of 10A to 40A. The phase angle firing control technique ensures a smooth and gradual step-less voltage control across the load. The facility is also provided to adjust the soft rise or fall in voltage across the heater load using on card Ramp Up and Ramp Down settings. The maximum and minimum output voltage across the heater load can also be adjusted. These regulators can be easily mounted inside the panel or on the base plate using 4 screws. For three-phase load in star with neutral or three-wire delta configurations, three independent regulators can be used with a common control signal.

Libratherm offers SCR triggering cards model LTC-12, which are designed to fire or trigger back to back connected SCRs using synchronized phase angle control technique. The card accepts analogue control signals of (0-5)/(0-10)VDC or (4-20)mA and provides proportional gate/cathode triggering pulses G1K1 + G2K2. These pulses can be used to trigger back-to-back connected SCRs upto 1000Amps with gate current upto 300mA. The card also provides built in regulated 5VDC supply to connect external potentiometer to manually control the SCR firing. The on card ramp up and ramp down settings allows gradual rise and fall of the voltage levels across the load.
