CCMmini DC Motor Speed Controller ... moreallows controlling direction of a DC motor using a Pulse-Width-Modulated(PWM) DC voltage with a Duty Cycle fully adjustable from 5%100% The motor speed controller can provide a continuous current of 3A to your DC motor or other DC load. Main technical parameters: l Input supply voltage: 6V-28VDC(max) l the maximum output power: 120W l the maximum continuous output current:3A l PWM frequency: 21kHz l Duty Cycle adjustable: 5%100% Specifications: l Item size:50*17*28mm l Four mounting holes of 3.5 mm each l Net weight: 30g Operating instruction: 1. Connect your motor(or DC load) to the motor terminals as indicated on the wiring diagram. 2. Connect a voltage of 6 to 28V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits. 3. You can now control the speed of the motor through potentiometer. Important Notes An appropriately rated fuse(rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation. 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.
