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 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 the reverse connection of power supply and control voltage over-voltage protection function. Note: This can NOT be used to the BRUSHLESS motor. The controller is NOT reverse-polarity protected and will be damaged if it connects the supply voltage with the wrong polarity. Features:- Control the speed of a DC motor with this controller. High efficiency, high torque, low heat generating. With reverse polarity protection, high current protection. Control voltage over-voltage protection function The overload and short circuit protecting current is 10A Working Voltage: DC 12V DC 40V. Control Power:0.01 400W. Static Current:0.02 A ( Standby ). PWM Duty Cycle:10% -100%. Specifications:- Input supply voltage DC 12V-40V The maximum output power 400W The maximum continuous output current 8A Static Current 0.02 A ( Standby ) PWM frequency 13kHz Material Plastic, metal Duty Cycle adjustable 10%-100% The operation environment temperature:-20-40 Dimension(cm) 6*5.5*2.8 Net weight 69g Package Includes: 1 x 12V-40V10A DC Motor PWM Speed Control Switch Governor
