Product Parameters:

1. Working voltage: DC 4.5 V – 35 V
   
2. Output current: 0 – 5 A
   
3. Output power: 90 W (maximum)
   
4. Quiescent current: 7 μA (standby state)
   
5. PWM duty cycle: 1 % – 100 %
   
6. PWM frequency: 20 kHz
   
7. Size: length 30 mm × width 26 mm (without handle) × height 14 mm
   
8. Weight: 0.013 kg

Precautions:

• DC motor governor input is DC, not directly connected to AC (for example: household 220 V AC), otherwise it will burn out!
  
• Do not reverse the positive and negative terminals of the DC power supply, otherwise the governor may be damaged.
  
• The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence.
  
• Adjusting the potentiometer knob can change the governor output duty cycle and the motor speed changes.
  

GREEN PWM

DC motor speed controller can easily provide 2 A continuous current for a DC motor or other DC loads. With self-recovery fuse 2 A and short LED light. PWM DC motor speed controller with switching function.

Technical Parameters

1. Input voltage range: DC 2.2 – 12 V
   
2. Output voltage: 1.8 – 12 V (adjustable according to the power supply voltage)
   
3. Output current: < 2 A
   
4. Connect the DC motor debugger to a direct power source. Do not directly connect to household 220 V AC power supply, otherwise you will be responsible for the damage!
   
5. The current of the governor is 2 A. If the connection current is greater than 0.5 A (for example, a 775 motor, baby-car motor, etc.), it cannot be driven, so please do not buy the wrong motor.
   
6. It is not recommended to use a power supply exceeding 12 V (e.g., a 12 V lead-acid battery), otherwise the governor may be damaged.

BLACK PWM

Description:

The PWM DC Motor Speed Controller Speed Switch Module 6 V / 12 V / 24 V / 28 V 3 A, which can regulate and boost voltage as it should.

There is a reversing three-position rocker switch on the controller board. Positions are CW – OFF – CCW. While the motor is on, you can turn the rotary knob to adjust the speed, in whichever direction the motor is going.

Specification

• Function: Speed Control
  
• Input voltage range: DC 6 – 28 V
  
• Current range: Within 3 A (maximum)
  
• Maximum output power: 80 W
  
• Switch function: None
  
• Duty cycle range: 0 – 100 %
  
• Size (L × W × H): Approx. 50 × 32 × 15 mm (1.3 × 2 × 0.4 inches)
  
• Net Weight: 1.13 ounces

Features

• Small, compact, snugly built, with a wide range of DC application
  
• Very smooth speed adjustment tool (PWM control) for LED lights and motors
  
• Easy installation with terminals is a nice touch
  
• The power/direction switch makes it one of the best choices for driving small to medium sized DC motors
  
• Potentiometer with switch function. The silver turning knob smoothly clicks at off position, and rotation allows very precise movement

PWM w/ LCD (General Features)

1.1 Equipped with start–stop button, and can be external switch control, to meet various customer control requirements.
1.2 Motor soft start function. When starting the motor, the current increases slowly and there is no shock current, which can effectively protect the motor and prolong its service life.
1.3 Duty cycle, duty cycle upper and lower limits, and working frequency can be set—this helps users operate and use their motors according to their working characteristics.
1.4 Digital encoder knob adjusts motor speed, which is more accurate and consistent than an ordinary potentiometer.
1.5 Comes with a standard 5135 instrument shell, convenient for customer installation.

Specifications

• Working voltage: DC 5 V – 30 V, input anti-reverse connection protection
  
• Rated current: 5 A (maximum current 15 A)
  
• Maximum power: 150 W
  
• Working frequency: 1 kHz – 99 kHz (adjustable, 1 kHz step), default frequency of 20 kHz, accuracy about 1 %
  
• Duty cycle: 0 – 100 %, 1 % step
  
• Product size: 79 × 43 × 26 mm

Operation Instructions

• In the default interface (the duty cycle is displayed by default)
  
• Short press → switch motor start and stop
  
• Long press → enter the setting interface
  
• Counterclockwise rotation → the duty ratio decreases
  
• Clockwise rotation → the duty ratio increases
