PWM regulation electronic switch control board is used to control analog circuits through the digital output of the microprocessor, which is widely used in many fields, including measurement, communication, power control and conversion, etc. Input voltage: 5-26V;Switching voltage: 5-12V (high and low level signal control);Current: 20A/50A/100A (self-); PWM (Pulse Width Modulation) is a technique that uses the digital output of a microprocessor to control an analog circuit. This technology enables control of analog signals by adjusting the pulse width of the output signal. PWM technology enables control of analog quantities such as motor speed, light brightness, etc. by changing the width of the pulse signal. PWM technology is also widely used in the automotive field, for example, in the charging circuit of electric cars CP terminal signals, pump power control circuits, and motor speed regulation. for the application of 20A, 50A, 100A field effect tubes, these high-power MOS tubes are commonly used in PWM regulated electronic switching control boards for the realization of electronic equipment power management and precise control of voltage and current.
