HARMNEE PWM DC motor speed controller is specially developed for motor DIY lovers. HARMNEE chooses high quality electronic components to make the controller and devotes to provide good experience for you. Perforated aluminium alloy case protects user from electricity and help heat dissipation. Display screen make you easily to know the real motor speed percentage of the rated speed. Potentiometer knob help you control the motor speed easily. The switch provides CW and CCW rotation direction choice for your motor. Hope HARMNEE motor controller take you good DIY experience.
LED Display ScreenDisplay the s percentage of real-time speed directly The displayed percentage ranges from 0% to 100% | Potentiometer KnobWith 100kΩ potentiometer, it adjusts the output voltage accurately to control motor speed The plastic knob can be separated from the potentiometer. Then you can fix the knob to your control panel | CW/CCW SwitchProvide forward and reverse rotation choice for you With only one switch, you can control the rotation direction easily | Perforated Aluminium CaseConducive to heat dissipation and protect the circuit The solid shell on the bottom protects the controller well. The holes on the back of the shell allow you to fix it |
HARMNEE motor speed controller applies to DC brush motor and need to match with DC power supply. It doesn’t fit for brushless motor or AC power supply.
HARMNEE motor controller is with rated current 40 amps and supports max current up to 60 amps. We advise you to ensure the rated current of your motor is less than HARMNEE motor controller’s rated controller. Recommended motor power is as below.
1. Before you attempt to wire the controller, make sure your power is off. And please turn off the switch on the speed controller.
2. Follow the wiring diagram on the controller, connect the wires between the power supply, controller and motor accurately. Please distinguish the positive and negative terminals for power supply.
Attention: Do NOT reverse positive and negative power loads, otherwise it will damage the controller.
3. Fix the motor in place. Then turn on the power and controller switch. Now adjust the potentiometer knob to control motor speed. The LED display will show you the real-time speed percentage.
4. If everything goes well, fix the controller in place somewhere. Enjoy your use experience.
