The dc motor speed controller allows controlling direction of a dc motor using a pulse-width-modulated (pwm) dc voltage with a duty cycle fully adjustable from 0 percent -100 percent. The circuit also includes a 10a fuse, with reverse connection of power supply and control voltage over-voltage protection function. Features: 100 percent brand new. Input supply voltage: Dc 12v-40v. The maximum output power: 400w. The overload and short circuit protecting current is 10a. Pwm frequency: 16khz. Duty cycle adjustable: 0-100 percent. The operation environment temperature: 20℃-40℃. The 10a fuse with reverse connection of power supply and control voltage over-voltage protection function. Can adjust the speed by the external 0-5v signal. Note: This can not be used to the brushless motor. The controller is not reverse-polarity protected and will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and for always turn off the power supply before making any wiring changes. Item size: 60 x 56 x 27mm. Net weight: 78g. Package included: 1x 12-40v 10a dc motor speed controller.
