PWM DC Motor Speed Controller 6V 12V 24V 28V 3A Variable Speed Control Switch Electronic Speed Controller Dimmer with Shell - uniquegoods 1206B

• 【Performance】Voltage range: Input DC 6V-28V voltage range is available. The rate current: 3A. PWM frequency: 21 kHz. Duty Cycle adjustable: 0%-100%. 【Potentiometer with Switch】Potentiometer speed adjustment with switching function, accurate and stable. With power indicator and white casing. 【Wiring】Connect the DC motor (or DC load) to the motor terminals. connect the 6V-28V DC voltage to the circuit to ensure that the polarity of the connection is correct. Note that the voltage applied to the motor will be the supply voltage applied to the circuit. power is turned on, power indicator is on, and the power is normal. potentiometer is adjusted to control the motor speed. 【Suggestion】An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation. 【Notes】The controller is NOT reverse-polarity protected and it 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., Weight: 1.48 ounces
