Features: This motor speed controller is suitable for AC220V 50 / 60HZ motor.Speed regulation range is 90-1400r / min 50HZ, 90-1700r / min 60HZ Suitable for packaging, printing, food, electronics, instrumentation, medical equipment, clothing industrial production line for speed control stick devices The controller uses high quality electronic circuitry and integrated components for durability. It has small size, high precision, wide speed control range, and long service life Notice: Actual color may be slightly different from the image due to different monitor and light effect Please allow 1-3cm deviation due to manual measurement Description: Material: electronic components Size: 60x90x100mm Packing: governor*1 Cable length: about 70CM Voltage: AC220V Control method: forward/reverse (adjustable) Installation form: panel screw installation Speed adjustment range: 90-1400r/min Main technical data: 1. Power supply: AC220V50/60Hz, voltage fluctuation range is plus or minus 10% Ue; 2. Use environment: -10~+50 3. The relative temperature is less than 90%; 4. Adjustment range: 90-1400r/min 50HZ, 90-1700r/min 60HZ Instructions for use: 1. Turn the external speed knob to "0" before use to avoid instantaneous large current and damage the controller 2. This product adopts generator feedback voltage control, and the control lines are divided into "blue", "yellow" and two wires. 3. If the speed controller is connected to the motor and the torque or speed does not meet the requirements, US-52 adjusts the side fine-tuning potential Device 4. To change the running direction of the motor: (1) If COM is connected with CCW, the motor will rotate forward. (2) If COM is connected with CW, the motor will rotate in reverse. 5. The action switch only controls the action or stop of the motor. It will not be used for power interruption. Please turn off the power if it is not used for a long time. Wiring: 6 single row Flat jack wiring diagram: main line-capacitor line-capacitor line-feedback line-feedback line-ground The main line is basically: red The capacitor line is basically: black, white The feedback line is basically: yellow, blue The ground wire is basically: green includes: 1xMotor Speed Point Regulator
