This motor speed controller is suitable for AC220V 50 / 60HZ motor.Speed regulation range is 90-1400r / min 50HZ, 90-1700r / min 60HZSuitable for packaging, printing, food, electronics, instrumentation, medical equipment, clothing industrial production line for speed control stick devicesThe controller uses high quality electronic circuitry and integrated components for durability.It has small size, high precision, wide speed control range, and long service lifeNotice:Actual color may be slightly different from the image due to different monitor and light effectPlease allow 1-3cm deviation due to manual measurementMaterial: electronic componentsSize: 60x90x100mmPacking: governor*1Cable length: about 70CMVoltage: AC220VControl method: forward/reverse (adjustable)Installation form: panel screw installationSpeed adjustment range: 90-1400r/minMain technical data:1. Power supply: AC220V50/60Hz, voltage fluctuation range is plus or minus 10% Ue;2. Use environment: -10~+503. The relative temperature is less than 90%;4. Adjustment range: 90-1400r/min 50HZ, 90-1700r/min 60HZInstructions for use:1. Turn the external speed knob to "0" before use to avoid instantaneous large current and damage the controller2. 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 Device4. 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 rowFlat jack wiring diagram: main line-capacitor line-capacitor line-feedback line-feedback line-groundThe main line is basically: redThe capacitor line is basically: black, whiteThe feedback line is basically: yellow, blueThe ground wire is basically: greenincludes:1xMotor Speed Point Regulator
