Item Type: Motor Speed Regulator Brand: BERM Model: US-52 Working Voltage: AC220V 50 / 60HZ (Voltage fluctuation range is 10% Ue) Matching Motor Power: 25W / 40W / 60W / 90W / 120W (optional) Operating Environment: -10 ~ + 50 Relative Humidity: Less than 90% Speed Range: 90-1400r / min 50HZ, 90-1700r / min 60HZ Note: The governor has 6 wires, the black wire is the main motor wire, the red and white are the capacitor auxiliary wires, the 2pcs blue wire are the speed feedback wires, and the green wire is the ground wire. Instructions: 1. Turn off the power, connect it according to the wiring diagram and confirm that the wiring is correct, do not modify it arbitrarily 2. Fix the controller and adjust the speed to the lowest "0" to avoid the instantaneous high current when starting the power supply, which will cause permanent damage 3. Then turn on the power again, adjust the speed knob to the required position, turn off the power when not needed 4. When the governor is connected to the motor, if you find that the torsion or speed does not meet the requirements, please adjust the trimmer potentiometer on the side of the product (speed setting adjustment) 5. To change the running direction of the motor, just change the jumpers of "CCW" and "CW" on the terminal block on the back of the controller. Select COM and CW short circuit, the motor will rotate CW; Select COM and CCW short circuit, then the motor will rotate CCW. (When changing the direction, wait for the motor to stop completely before changing.) 6. The action switch only controls the movement or stop of the motor. It is not used for power interruption. Please turn off the power if it is not used for a long time. Application: It is widely used in the production line of packaging, printing, food, electronics, instrumentation and clothing industry as a speed regulating drive device. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
