Features: 1. Small size, low energy consumption, wide speed range. 2. Long service life, fine mechanical properties, easy and convenient to use. 3. Electronic circuits and integrated components, small size, low energy consumption, wide speed range. 4. Single phase capacitor start, can be combined with single phase asynchronous motor, miniature gear reducer and speed sensor to form mechatronics products. 5. Widely used in packaging, printing, food, electronics, instrumentation, machinery and other industries of the production line to do speed regulation, drive devices. Notice: Objects may have Logo, if you want to know, please contact us. Otherwise, please do not bid. How to Use: 1. Turn off the power, connect according to the wiring diagram and confirm that the line connection is correct, do not arbitrarily modify it; 2. Adjust the external speed knob to “0” before use to avoid instantaneous high current and damage the controller. 3. This product adopts generator feedback voltage control, and the control line is divided into two lines: “lan” and “yellow”. 4. If 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). 5. To change the direction of motor operation, just replace the “CCW” and “CW” on the terminal on the back of the controller. Note: 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 short circuit, then the motor rotates counterclockwise. 6. 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.
