5A PWM Max 90W DC Motor Speed ​​Regulator 5V-35V Speed ​​Regulator Switch LED Dimmer

Material: MetalColor: SilverShaft diameter: 5mmWorking voltage: DC4.5V-35VOutput current: 0-5AOutput power: 90W (maximum)Quiescent current: 7uA (standby state)PWM duty cycle: 1%-100%PWM frequency: 20khzSize: about 3026height 14MM (without handle)Weight: about 13 gramsPackage includes: 1*5APWM DC motor speed switchApplication: DIY model car, small electric drill, micro machineFeatures:1. Front and rear double ball bearings, high speed and wear resistance, with cooling fan.2. High torque, low noise. - This is an ultra-mini motor with the best performance.3. Suitable for car wash pumps, sprayers, fans, grinders, etc., also suitable for DIY.4. Very suitable for rusty or damaged DC gear motors on machines.5. Metal back cover, yellow dot is positive.Notes:1. Do not connect the positive and negative poles of the DC power supply in reverse, otherwise the speed regulator may be damaged.2. The DC motor speed regulator input is DC power, and cannot be directly connected to AC power (for example: household 220V AC power), otherwise it will burn out!3. The motor can be forward or reverse. When the running direction is inconsistent with the expected direction, the direction can be changed by adjusting the line sequence. Adjusting the potentiometer knob can change the output duty cycle of the speed regulator, and the motor speed will change accordingly.
