Function: Speed control motor controller range is 90-1400r/min and 90-1700r/min at 50/60Hz respectively. The control precision is high, and micro-control of the motor speed is realized. The working of the product is simple, which allows novices to quickly learn and master the method of action. Widely used in packaging, printing, food, electronics, instrumentation, medical equipment, garment industry production line as speed drive device. Specification:Product Model: US-52Matched Motor Power: 300W; 400W; 500W (Optional) Working Power Supply: AC220V 50/60HZ (Voltage Fluctuation Range ± 10% Ue)Use Environment: -10 - +50°C Relative Strength: lt; 90%Speed Range: 90-1400r/min 50HZ, 90-1700r/min 60HZLast Packing:1*Motor Speed ControllerNote:The actual color of the product may be different from the picture due to the light. There may be a slight deviation in the measurement of the product. Installation and use method: The driver has 6 lines, the black line is the main line of the motor, the red and white lines are the secondary lines of the capacitor, 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 the line connection is correct, do not modify it arbitrarily; Set the external speed knob to "0" before use to avoid transient high currents and damage the controller. This product is controlled by the generator feedback voltage, and the control wire is divided into two lines: "blue" and "yellow". When the regulator is connected to the motor and determines that the torque or speed does not meet the requirements, the US-52 adjusts the side potentiometer of the trimmer (speed adjustment). To change the working direction of the motor, you only need to replace the jumper "CCW" and "CW" on the wiring on the back of the controller.* When changing the direction, you need to change the motor after the operation is completely stopped.1) select the short circuit COM and CW, then the motor rotates clockwise; 2) select COM and CCW for short, then the motor rotates counterclockwise. The action switch only controls the motor for operation or stop, and does not use power until the interruption. If it is not used for a long time, please turn off the power.
