5V-28V 5A PWM DC Motor Speed Control Switch Controller Volt Regulator LED Dimmer

Features:Made with high quality circuit board which ensures a longer service life.Equipped with fuse tube to protect the speed controller from burning out that short circuit causes.Controls the speed of a DC motor with this controller High efficiency, high torque and low heat generation.With reverse polarity protection, high current protection Operating.Adjusting the potentiometer knob changes the governor output duty cycle and the motor speed changes.Specification:Item Type: PWM Motor Speed Control SwitchMaterial: Electronic ComponentsWorking Voltage: DC 4.5V-28VOutput current: 0-5AOutput power: 90W (maximum)Quiescent current: 7uA (standby state)PWM duty cycle: 1%-100%PWM frequency: 20khzWeight: Approx. 16gPackage list:1 x Motor Speed Controller SwitchNotes:The input of the DC motor governor is DC power, and it is not directly connected to AC power (for example: household 220V AC), otherwise it will burn out! ! !Do not reverse the positive and negative terminals of the DC power supply, otherwise the governor may be damaged.The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence.Adjusting the potentiometer knob changes the governor output duty cycle and the motor speed changes.
