SMAKN CCMHCW DC 12V-40V 400W 10A Adjustable DC Motor Speed Controller PWM Controller

*DC Motor Speed Controller allows controlling speed of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100%.
*The motor speed controller can provide a continuous current of 8A to your DC motor or other DC load.
*The circuit also includes a 10A fuse, with reverse connection of power supply and control voltage over-voltage protection function.
Main technical parameters:
*Input supply voltage: 12V-40VDC
*The maximum output power: 0.01-400W
*The maximum continuous output current :8A
*The overload and short circuit protecting current is 10A.
*PWM frequency: 13kHz
*Duty Cycle adjustable: 10%-100%
*The 10A fuse with reverse connection of power supply and control voltage over-voltage protection function Specifications:
*Item size:60*55*28mm
*Net weight: 66g
Important Notes:
*An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe.
*The controller is with reverse-polarity protection and the fuse will be damaged if connect the supply voltage with wrong polarity.
*Double check all connections before applying power and always turn off the power supply before making any wiring changes.
