Product Description:
Mini 5A PWM DC Motor Speed Controller Module (3V–35V) – LED Dimmer Switch
The Mini 5A PWM DC Motor Speed Controller Module is a compact, efficient, and versatile solution for regulating DC motor speed or dimming DC-powered LED lights. Based on PWM (Pulse Width Modulation) technology, this controller allows you to adjust motor speed or brightness precisely, making it ideal for applications like cooling fans, LED dimming, motor-driven automation, and more.
This module supports a wide input voltage range of 3V to 35V DC and delivers up to 5A of continuous current, protected by a self-recovery fuse for safe and stable operation.
