This 12V-40V 10A PWM High Power DC Motor Speed Controller lets you control the speed of a DC motor using a Pulse Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 10%-100%. It can be used to drive all DC Brushed Motors that work between 12V-40V DC and consume up to 10A of current. The circuit also includes a 10A fuse, with the reverse connection of power supply and control voltage over-voltage protection function.

Features:

• Control the speed of a DC motor with this controller.
• High efficiency, high torque, low heat generating.
• With high current protection.
• Control voltage over-voltage protection function
• The overload and short circuit protecting current is 10A
• Working Voltage: DC 12V – DC 40V.
• Control Power:0.01 – 400W.
• Static Current:0.02 A ( Standby ).
• PWM Duty Cycle:10% -100%.

Applications:

• For Speed Control Of all Types of DC Brush Motors
• For Controlling Automotive Cooling Fan Speed, Auto Fan Speed, Windshield Wipers, Auto Air Conditioning.
• For Controlling Belt Speed, Pipeline Exhaust Fan Speed, Treadmill Speed, Multi-Speed Parallel Computer Fan, Electronic Fan Speed.

Note: This can NOT be used to the BRUSHLESS motor. The controller is not reverse-polarity protected and will be damaged if it connects the supply voltage with the wrong polarity.
