RGC1P48V30ED Semiconductor relay RGC1 proportional, 1-pole, 30 A, 190 - 550 V

The RGC1P is a proportional single-phase thyristor controller with an integrated heat sink that can be used to regulate the power of single-phase loads via an analogue control input. Control input versions AA and V cover various control current and control voltage ranges. The operating mode is selected via a second rotary knob on the front. You can choose between phase-angle control, full-wave control and extended full-wave control. In addition, a soft start function is available to limit the inrush current for loads with high temperature coefficients (e.g. short-wave infrared heaters). The output of the RGC1P is protected against overvoltage by an integrated varistor between the output terminals. Two LEDs on the front panel indicate the current state of the load and controller.
