DC12V PWM DC Fan Speed Controller | Variable Speed Temperature Module with Probe and High-Temperature Alarm

The DC12V PWM DC Fan Speed Controller is a versatile, microcontroller-based module designed to regulate up to three DC fans efficiently. It features intelligent PWM control, automatic temperature-based speed adjustment with a dedicated probe, and a high-temperature alarm for enhanced safety.

This DC fan temperature control module supports up to three 4-wire DC fans, making it ideal for electronics cooling, PC builds, automation, and industrial temperature-sensitive applications. With flexible DIP switch settings, onboard potentiometers, and stall alarm protection, this module is perfect for maintaining optimal cooling and protecting against overheating or fan failure.

Features:

• PWM-based speed control for up to 3 DC fans (4-wire compatible).
• Built-in temperature sensor probe for automatic speed adjustment (FAN1).
• High-temperature alarm and fan stall detection (LED and buzzer alerts).
• DIP switch settings for customizable control regions and alarms.
• Supports up to 5A current per channel, 9A total bus current.
• Wide output range (channel 1: 20–100% PWM, 40–100% with TFL ON; channel 2/3: 10–100%).
• Application in PC cooling, electronics enclosures, industrial machinery.
