Supply Voltage: DC 4.5V-35V 5A
Control power: 90W (max)
Size: 30 x 26 x 14 mm (Without Handle)
PWM duty cycle: 1% -100%
PWM frequency: 10khz

he major use of this circuit are:

DC Air Cooler , DC Pedestal Fan , DC Lights

Note:

This Circuit Will Only Work With those Motor's which is directly connected to this module. if motor already connected with another control circuit or kit, please detach the motor from that circuit for proper operation.

DC motor Speed Controller input is DC, can not directly connected to the AC (for example: home 220V AC), otherwise it will burn!

DC power supply positive and negative terminals do not reverse, otherwise the DC motor Speed Controller may be damaged.

The motor can be positive or negative, when the direction of operation and expectations do not match, you can adjust the line order to change the direction.

Adjust the potentiometer knob to change the Speed Controller output duty cycle, the motor speed changes.
