DC Motor Speed Controller, the full name of pulse width modulation is Pulse Width Modulator. Abbreviation PWM. DC motor governor is a device for adjusting the speed of a DC motor. DC motor has the characteristics of low speed and large torque which can not be replaced by the AC motor. Therefore, the equipment that regulates the speed of the DC motor - DC governor can be widely used.It is often used in DC load circuits due to its special properties. Lamp dimming or DC motor speed regulation, HW-1020 governor are made by pulse width modulation (PWM) principle. Such as Motor governor and PWM governor.
Industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting and lighting mediation, computer power supply cooling, DC fan, etc., have been widely used.
At the same time, it can display the speed percentage, the displayed value is the ratio between the current speed and the full speed.For example: The display screen ‘028’, it means the current speed is 28% of full speed.
1>. High frequency 13Khz, the purer the signal;
2>. PWM can be adjusted 0%-100%;
3>. Support high current;
4>. High quality knob;
5>. The knob is separated from the module, and the application is more convenient;
6>. Plastic shell, safe and reliable;
7>. LED display;
8>. No polarity regulation.
1>. Input voltage: DC 6-30V;
2>. Load power: 150W(MAX);
3>. Rated current: 5A;
4>. Peak current: 15A;
5>. Speed range: 5%-100%;
6>. PWM frequency: 13Khz;
7>. Potentiometer: resistance value 100K;
8>. Knob inner diameter: 8mm;
9>. The output voltage is 0-100% of the input voltage;
10>. Standby current: 0.02A;
11>. Size(without Knob): 78*44*24mm;
12>. Cable Length: 19mm.
1>. Turn the potentiometer counterclockwise.
2>. Connect DC motor or lamp which meets the requirements at ‘MOTOR+’ and ‘MOTOR-’.
3>. Connect DC power supply at ‘POWER+’ and ‘POWER-’.
4>. Adjust knob to control speed for motor while check speed percentage on display screen.
5>. If need to stop,you can turn the potentiometer counterclockwise.
6>. Remove power supply before remove DC motor.
7>. Remove DC motor.
1>. Industrial DC motor speed regulation;
2>. Industrial conveyor belt speed regulation;
3>. Lighting and lighting mediation;
4>. Computer power supply cooling;
5>. DC fan.
1>. It is working for DC motor and just can connect to DC power supply.So please don’t connect AC 110V or 220V power supply!Otherwise it will damage the module!
2>. The positive and negative poles of the DC power supply can not be reversed, Otherwise the governor will damage.
3>. Motor can be divided into positive and negative, when the direction of operation and expectations are inconsistent, you can change the direction of the alignment.
4>. The potentiometer knob can change the output duty cycle of the governor, thus changing the speed of the motor.
5>. Please allow 1-3mm differs due to manual measurement.
1>. 1pcs DC Motor Speed Controller with display.
