PWM 4 DC Fan Temperature Speed Controller Board

The DC12V PWM DC Fan Speed Controller is a versatile device designed for controlling the speed of DC fans. Operating on a 12V power supply, this controller utilizes Pulse Width Modulation (PWM) to regulate fan speed. It includes a temperature probe for monitoring, and it can trigger a high-temperature alarm. This controller provides precise fan speed adjustments based on temperature changes, making it suitable for applications requiring temperature-sensitive cooling.
