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

5V-28V 5A PWM DC Motor Speed Control Switch Controller Volt Regulator LED Dimmer. 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. Good value for the money spentification: Item Type: PWM Motor Speed Control Switch Material: Electronic Components Working Voltage: DC 4.5V-28V Output current: 0-5A Output 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 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: 1. Please allow 0~1 inch error due to manual measurement. Thanks for your understanding. 2. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.
