Product Descriptions 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%-100%. The motor speed controller can provide a continuous current of 10A to your DC motor or other DC load. The circuit also includes a 8A fuse, with reverse connection of power supply and control voltage over-voltage protection function. Features: 100% brand new and high quality Input supply voltage: DC 10V-40V The maximum output power: 150W The maximum continuous output current :8A The overload and short circuit protecting current is 15A PWM frequency: 16kHz Duty Cycle adjustable: 0-100% The operation environment temperature:-20℃-40℃ The 8A 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 always turn off the power supply before making any wiring changes. The use of 0-5V external voltage control line description The speed controller supports the use of an external DC voltage control. Using the following steps: First,remove potentiometer. (you may take it down from one side of the circuit board or potentiometer side down under your need); Second, connecting 0-5V DC control signal to the middle pin marking 0-5V; Third, connecting the earth wire of 0-5V DC control signal to the connecting piece on the pin marking GND;
