Single Phase Scr Based Power Regulator

Libratherm offers Single phase power regulator model LTC-16 for Heating control of resistive or inductive loads. It is designed using back to back SCRs having PIV as high as This regulator accepts the user selectable control signal of 0-5V, 0-10V and 4-20mA or through potentiometer. The average output voltage across the heaters can be varied proportional to the input signal. The built in back to back connected SCR can control the load up to 20A and 40A. The phase angle firing control technique ensures smooth and gradual voltage control across the load. Facility is also provided to adjust the soft rise or fall in voltage across the load using on card Ramp UP and Ramp Down potentiometers. The maximum and minimum voltage output can also be adjusted. LTC-16 can be easily mounted on the standard 35 mm. DIN rail.
