This DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%.The motor speed controller can easily provide a continuous current of 5A to your DC motor or other DC load.
Specifications:
Operating voltage: DC 5V-35V
Control power: Maximum 90W
Quiescent current: 7uA(Standby)
PWM duty cycle: 1%-100%
PWM frequency: 20khz
Shell size: 30mm*26mm(Without handle) total height is 14mm
Note:
1. The input of the DC motor speed controller is DC, and it cannot be directly connected to AC (for example: 220V AC 220V), otherwise it will burn.
2. Do not reverse the positive and negative terminals of the DC power supply, otherwise the governor may be damaged.
3. The motor can be positive or negative. When the operation direction does not match the expectation, the line sequence can be adjusted to change the direction.
4. Adjust the potentiometer knob to change the output duty cycle of the governor, and the motor speed changes.
Package includes:
5 x DC 5V~35V Mini DC Motor
1 x 24AWG red and black cable 50 cm each

These are great for usb devices like external fans used to cool things like routers and gaming consoles. Some of my blower fans are too powerful and loud at its on setting but these voltage governors let me set them to run at lower and quieter speeds.
