Description Overview 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 5%-100%. The motor speed controller can provide a continuous current of 3A to your DC motor or other DC load 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. Specifications Input Supply Voltage: 6V~28VDC max Maximum Output Power: 80W Maximum Continuous Output Current: 3A PWM Frequency: 21kHz Duty Cycle adjustable: 5%-100% Dimensions: 66x32x24mm Net Weight: 40g More Products View More Products

Description: PWM DC Motor Speed Switch Controller 10V 12V 24V Control Reversible Regulator High efficiency, high torque, low heat generating Control the speed of a DC motor with this controller With reverse polarity protection, high current protection Specifications: Material: Plastic, metal Input: 10V-30V Output: Max 120W (When more than 24V) PWM range: 5%-95% Frequency: 500Hz Current: Max 4A (Recommend you to use in 3A) Operating Instruction: 1. Connect it to the power, ensure the positive inversion switch located in the middle of the zero, and connected with a DC power supply (the DC supply voltage range is more than 6V and less than 30V). Warning: do not reverse the positive and negative terminals of DC power source, otherwise regulator may be damaged. 2. Connect it to the motor, the motor line can be positive or negative, when the running direction is not consistent with the expectative one, you can adjust the sequence of lines or switch position to change the direction. 3. Adjust the switch. Positive inversion switch is used to control the motor speed direction. When the switch is located on the zero position, the motor stops rotating. 4.Adjust the potentiometer knob. Adjusting potentiometer knob can change output duty ratio of the regulator, then motor speed change. Package included: 1 x DC Motor Speed Controller Details pictures:
