This DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM). Its perfect for applications like fans, etc. providing a nice adjustment of motor speed.

How to use:

1. First, remove the potentiometer. (you may take it down from one side of the circuit board or potentiometer side down under your need);
2. Second, connecting 0-5V DC control signal to the middle pin marking 0-5V;
3. Thirdly, connecting the earth wire of 0-5V DC control signal to the connecting piece on the pin marking GND;

Note:

1. This can NOT be used to the BRUSHLESS motor.
2. Do not reverse the positive and negative terminals of the DC power supply, otherwise, the governor may be damaged.
3. The motor can be positive or negative, regardless of when the direction is inconsistent with expectations, can be changed by adjusting the direction of the line sequence.
4. Adjustment potentiometer knob to change the governor output duty cycle, the motor speed change.
5. With the use of a 0-5V external voltage control line, the speed controller supports the use of an external DC voltage control.

Features:

1. Wide operating voltage: DC 6V-DC 90V, max. power: 1000W.
2. A PWM speed controller, enables you to control the speed of DC motors smoothly.
3. This motor speed control switch can control the motor speed from between 0% -100%.
4. Support PLC control, stable performance, high efficiency and low noise.
5. Suitable for applications like fans, etc. providing nice adjustment of motor speed.
