Description:
PWM motor speed controller
This product brings together a wide range of modern motor speed control, with the advantages of small size, simple operation, high current resistance and reverse connection. Suitable for most users in various environments with various speeds, support acceleration and deceleration functions can be set through the menu, with set parameters power off permanent memory function

Product manual:
Voltage: DC8V-55V (wide voltage anti-back protection)
Speed range: long press / short press to adjust the degree, 0% -100% speed
Drive current: up to 10A, (recommended output series 12A fuse)
Standby current: <17mA
Mounting hole: diameter 3mm
Product size: 64mm*35mm*19mm (length * width * height)
Working temperature: -20 ° C ~ 70 ° C

Instructions:
1. Click/long press the "speed increase" button to increase the motor speed to 100%.
2. Click/long press the "speed down" button to increase the motor speed to a minimum of 0%.
3. Press and hold the "Power On/Off" button for one second, the controller will be turned on or off (the power is turned off by default, and the memory function is activated after booting)

Precautions:
1. The digital tube flashes at the moment of power-on (normal phenomenon, no need to worry)
2, close to the limit drive current working conditions, it is recommended to take the output end of the fuse
3. The DC motor speed controller cannot be installed in places where there is dripping water and children can reach it.
4. After wiring, check if the line is correct and then energize, so as to avoid accidentally burning the temperature controller and load device.

Wiring:
"M+" and "M-" are respectively connected to the positive and negative terminals of the output, M+ is positive and M- is negative.
"VIN" and "GND" are respectively connected to the positive and negative terminals of the input terminal, Vin is positive and GND is negative (input power supply voltage is DC8V-55V)

Package included:
1 x DMC-331 DC8V-55V 10A DC PWM Motor Speed Controller LED Digital Adjustable Speed Regulator Control Governor Switch 12V 24V 36V 48V
