modname=ckeditor

SCR series thyristor-controlled DC motor speed control board is a new low-power DC motor speed regulator designed and developed by the company with reference to similar products at home and abroad and combined with actual use conditions. It has the advantages of small size, convenient installation, high speed regulation accuracy, low price and complete functions. It is widely used in various industries such as bag making machine, cross cutting machine, wire drawing, extrusion machinery, food production, printing and packaging, etc., and can be used with permanent magnet, other excitation and parallel excitation DC motors.

Supply power to the armature of small DC motor, so that the DC motor can achieve constant torque stepless speed regulation. The main circuit of the device adopts a single-phase bridge semi-control circuit, with voltage negative feedback, current cut-off feedback circuit and soft start, etc., to improve the speed regulation accuracy, limit the starting current, the control circuit is triggered by a single-junction transistor, and the circuit circuit is simple , the work is stable and reliable, and the temperature compensation performance is stable.

External control includes: displacement controller, NPN or PNP photoelectric switch.
