DCRG-200/800W series silicon controlled DC motor speed control board has the advantages of small size, easy installation, high speed control accuracy and low price. It is widely used in wire, cable, light industry, textile, paper making, chemical industry, printing and dyeing, metallurgy, rubber and plastic, wire drawing, extrusion machinery, medical equipment, food production, printing and packaging, etc. The industry can be used in conjunction with permanent magnet, self excitation, parallel excitation and series excited DC motors.
The small DC motor armature is supplied to make the DC motor achieve constant torque and stepless speed regulation. The main circuit of the device adopts single-phase bridge semi-control circuit with voltage negative feedback, current cut-off feedback circuit and soft start, which improves the speed control accuracy, limits the starting current, and adopts single-junction transistor trigger. The circuit is simple, stable and reliable, and the temperature compensation performance is stable.
External control includes: displacement controller, NPN or PNP photoelectric switch, Hall dual-speed controller, computer or inverter analog output DC0-10V stepless control. Instead of SCR-08 DC motor speed control board.
