Feature:The speed control range of motor governor is 90-1400r or min and 90-1700r or min respectively at 50 or 60Hz.The controller is manufactured with high quality electronic components, and its performance is stable and reliable.The control precision is high and the micro-control of motor speed is realized.The operation of the product is simple, which enables novices to learn and master the operation method quickly.Widely used in packaging, printing, food, electronics, instrumentation, medical equipment, clothing industry production line as speed drive device.Specification:Product model: US-52-REDMatching motor power: 300W 400W 500W (Optional)Working power supply: AC220V 50 or 60HZ (Voltage fluctuation range 10 percent Ue)Use environment: -10-and50Relative humidity: andlt 90 percent Speed range: 90-1400r or min 50HZ, 90-1700r or min 60HZPackage list:1 x Motor Speed ControllerNote: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 usage 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 (speed setting adjustment).To change the direction of motor operation, simply replace the jumper "CCW" and "CW" on the wiring on the back of the controller. x When changing direction, you 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.The action switch only controls the motor to operate or stop, and does not use the power supply for interruption. If it is not used for a long time, please turn off the power.
