Product Details

12V-40V 120w MAX PWM DC Motor Speed Control

Features:

DC Motor Speed Controller allows controlling both the speed
and direction of a DC motor using a Pulse-Width-Modulated (PWM) DC
voltage with a Duty Cycle fully adjustable from 10%-100% (both Positive
and Negative DC output).
The motor speed controller incorporates a high power MOSFET with a
heat sink and can easily provide a continuous current of 3A to your DC
motor or other DC load. The circuit also includes LED whose brightness
varies proportional to the relative speed of the motor therefore giving a
visual feedback of the current speed.

Main technical parameters:

Input supply voltage: 12V-40VDC(max)
the maximum output power: 120W
the maximum continuous output current :3A;
The overload and short circuit protecting current is 5A
PWM frequency 15kHz
Duty Cycle adjustable: 10%-100%
Power-On LED indicator
The positive inversion switch is used to control the direction
The potentiometer with open and closing function.

Specifications:

Item size: 70*39*31mm
Net weight: 72g

Important Notes
An appropriately rated fuse (rated a little higher than the maximum
current you expect to draw) is recommended to ensure safe operation.

The controller is NOT reverse-polarity protected and will be

damaged if connect the supply voltage with wrong polarity. Double
check all connections before applying power and always turn off the
power supply before making any wiring changes.

Package include:
1 x 12V-40V Speed Control Switch
