Features 【Range Of Governor】AC Motor Speed Controller 's speed control range of motor governor is 90-1400r/min and 90-1700r/min respectively at 50/60Hz 【Stable Performance】Motor Speed Controller is manufactured with high quality electronic components, giving stable performance that prologs service life 【Micro-control】Motor Speed Governor's high control precision realizes the micro-control of motor speed, more accurate and reliable 【Easy To Use】Electric Motor Speed Controller with simple operation, which enables novices can quickly learn and master 【Wide Application】Motor Speed Controller can Widely used in packaging, printing, food, electronics, instrumentation, clothing industry production line as speed drive device Specification: Product model: US-52-RED Matching motor power: 300W; 400W; 500W (Optional) Working power supply: AC220V 50/60HZ (Voltage fluctuation range ±10% Ue) Use environment: -10~+50℃ Relative humidity: <90% Speed range: 90-1400r/min 50HZ, 90-1700r/min 60HZ Package list: 1 * Motor Speed Controller Note: The actual product color may deviate from the photo due to light. There may be a slight deviation in the measurement of product. Installation and use method: The controller has 6 lines, the black line is the main line of the motor, the red and white are the capacitor secondary lines, the two blue lines are the speed feedback line, and the green line is the ground line. Turn off the power, connect according to the wiring diagram and confirm that the line connection is correct, do not arbitrarily modify it Set the external speed knob to "0" before use to avoid transient high currents and damage the controller. This product is controlled by generator feedback voltage, and the control line is divided into two lines: "blue" and "yellow". When the governor is connected to the motor and found that the torque or speed does not meet the requirements, the US-52 adjusts the side trimmer potentiometer To change the direction of motor operation, simply replace the jumper "CCW" and "CW" on the wiring on the back of the controller.         * changing direction, must change the motor after it has completely stopped running.         1) Select COM and CW short circuit, then the motor rotates clockwise;         2) Select COM and CCW to short, then the motor rotates counterclockwise.
