 9-50V 40A 2000W HHO comtrol  PWM dc motor governor external speed switch 

IMDN10 dc governor.The governor is a 9-50V voltage universal dc governor.The imported field effect power tube/imported special speed-regulating drive IC/PCB is 2oz 70 micron copper sheet, and the large current balance type PCB layout makes the output PWM waveform perfect and more efficient.



(1)The Operating voltage:DC10V-50V

(2)The Control Power: 0.01-2000W(The max starting current 40A,Under 20A for long working time

Different operating voltage compared to the different control power 

as below:

Operating Voltage12V  12V*40A =480W

Operating Voltage24V  24V*40A =960W

Operating Voltage36V  36V*40A =1440W

Operating Voltage40V  40V*40A =1600W

Operating Voltage50V  50V*40A =2000W

(3)The Static Current: 0.025A(Operating Voltage between(from DC10V to DC50V,The static Current won't be over25mA)

(4)PWM Duty Ratio:5%-100%


(6)Operating temperature:-20℃- -40℃ 

(7)Circuit dimension:90*51*30mm


1.Before shipments,potentiometer is separaed with the case, for protecing during the shipments

2.Wire connection: The positive and negative poles of the power supply must not be connected in reverse

3. The  governor is DC  governor , The power must be 9-50V

The main purpose :

1, All kinds of general dc brush motor speed


2. Motor speed regulation for all types of automobiles (speed regulation by automobile cooling fan, automobile fan, automobile windshield wiper motor and automobile air conditioning fan)


3. Production line conveyor belt speed regulation, pipe exhaust fan speed regulation, treadmill speed regulation, multiple computer fans parallel speed regulation, electronic fan speed regulation.


4, all kinds of dc bulb dimming, all kinds of dc heater temperature regulation.
