SKJ-1B AC Motor Speed Control ControllerAdopting innovative electronic circuits, it has the characteristics of small size, high precision, wide speed range, and low power consumption, achieving the function of feedback constant speed and stepless speed regulation for single-phase motors. Widely used in industries such as packaging and printing, instrumentation, clothing machinery, medical machinery, etc., it is interchangeable with similar products produced by Japan's Dongfang Electric Corporation and Taiwan's Shangyang Electric Corporation.
2、 Main technical data:
1. Working power supply: AC220V 50/60HZ ， Voltage fluctuation range plus or minus 10% Ue;
2. Rated power: 16W, 25W, 40W, 60W, 90W, 120W, 180W
3. Usage environment:- 10~+50℃；
4. Relative humidity less than 90%;
5. Speed range: 90-1400r/min 50HZ, 90-1700r/min 60HZ
3、 Instructions for use:
Before use, adjust the external speed knob to "0" to avoid generating momentary high current and causing damage to the controller.
2. This product adopts generator feedback voltage control, with control lines divided into "blue" and "yellow" wires.
3. If the torque or speed does not meet the requirements when connecting the speed controller to the motor, adjust the US-52 side fine adjustment potentiometer.
4. To change the direction of motor operation: 1) Select COM and CW short circuit, and the motor will rotate forward.
2) If COM and CCW are short circuited, the motor will reverse.
5. The action switch only controls the motor to move or stop, and is not used for power interruption. If not used for a long time, please turn off the power.
6. This product comes with motor models including YYDJ, YCJT, YYCJ, and YCJFK series motors
