Input supply voltage: DC 12V-40V
The maximum output power: 0.01-400W
The maximum continuous output current :8A
Static Current:0.02 A ( Standby )
The overload and short circuit protecting current is 10A
PWM frequency: 13kHz
Duty Cycle adjustable:10%-100%
With 10A fuse, with power reverse, control voltage overvoltage protection

Notes and instructions for use
1. The input of the DC motor speed controller is DC power, and it should not be directly connected to AC power (such as household 220V AC power), otherwise it will burn out
2. The positive and negative poles of the DC power supply cannot be reversed, otherwise the speed controller will be damaged
3. The motor can be neither positive nor negative. When the running direction is not consistent with the expected direction, the direction can be changed by adjusting the wire sequence
4. The potentiometer knob can change the duty cycle of the governor output, thereby changing the motor speed

Package include:
2 x PWM DC motor speed controller
