Motor Speed Regulator, DC 12 to 80V 30A PWM Soft Start Stop Digital Display Speed Controller for Brushed DC Motor

Item Type: DC Motor GovernorMaterial: PCBInput Voltage Range: DC 12-80VApplicable Current Range: Up to 30ASpeed Range: 0%-100%Frequency: 21KHzPackage List：1 xDC Motor Governor1 x Display ScreenNote:1. Pay attention to the correct operation.2. Please note that the input of this DC motor controller is connected to DC, not AC, otherwise it will burn.3. Please make sure that the positive and negative poles are connected correctly, otherwise the controller will be damaged.

• This DC motor governor measures 15 x 12 x 7 cm and operates on DC 12-80V input with up to 30A current. The PCB-based unit features a 21KHz PWM frequency and 0% to 100% speed regulation range.
• The soft start and soft stop function gradually ramps motor speed up on start and down on stop. This design reduces mechanical stress on the motor shaft and extends the operational life of connected equipment.
• The digital display panel shows real-time speed readings for precise monitoring and adjustment. Multiple ventilation holes on the housing help dissipate heat during prolonged operation to maintain device service life.
• The speed regulator connects to DC brushed motors with correct input polarity observation. Turn the control knob clockwise to increase speed and counterclockwise to decrease, with zero speed at the lowest position.
• This motor speed controller works well for DIY robotics projects, small electric tools, cooling fans, mini water pumps, and hobbyist experiments. The compact size allows easy placement in tight equipment spaces.
