PWM DC Motor Speed Control Switch Governor 12V-40V 10A

From the shop's description

PWM DC Motor Speed Control Switch Governor Module 12V-40V 10A The 12V to 40V 10A DC Motor PWM Speed Controller is expertly designed for controlling the speed of DC motors. It utilizes a Pulse-Width-Modulated (PWM) DC voltage, allowing for a fully adjustable duty cycle from 10% to 100%. This versatility makes it an ideal choice for a wide range of applications. Warning! Only for Brushed DC Motors. DO NOT use it for Brushless motors. Features PWM (Pulse Width Modulation) speed controller Reverse polarity protection 400W of maxium power output Built in 10A Fuse Overload and short circuit protection specifications Adjustment range: 12 V to 40 V Maximum power: 400 W Maximum current: 10 A Built-in fuse: 10 A Adjustable Duty Cycle: 10% to 100% PWM Frequency: 13 KHz Controller: NE555 system Potentiometer for engine speed control Connection via a screw connection: Power +: module supply voltage Power -: system weight Motor +: engine outputs Motor – : engine outputs Dimensions: 60 x 55 x 27 mm (without knob) The connectors are properly signed on the back of the plate. Connection The module has four screw terminals, two of which are used to connect the power supply, and another two to connect the DC motor. The connectors are properly signed on the back of the board. Pin Description 1 The engine’s output. 2 The engine’s output. 3 Ground. 4 Module supply voltage 5 Potentiometer for motor speed control.
