The PWM Motor Speed Controller (12V DC) is a compact and essential tool for precisely managing the airflow and noise levels of cooling fans. At Electrapac, we recommend this module for PC enthusiasts, server maintenance, and DIY electronics projects where temperature management and silent operation are priorities.
This regulator uses Pulse Width Modulation (PWM) to adjust the speed of DC motors and fans. Unlike simple voltage dimmers, PWM maintains higher torque at lower speeds and is significantly more energy-efficient, making it ideal for 12V DC systems
For a reliable setup using components from
Input Power: Connect your 12V DC source to the "IN+" and "IN-" terminals. Ensure correct polarity to avoid blowing the integrated fuse.
Fan Connection: Connect your 3-wire or 2-wire fan to the "OUT" terminals.
Operation: Turn the knob clockwise to click the unit "ON." Continuing to turn clockwise will smoothly increase the fan speed to its maximum.
Note: This controller regulates speed by adjusting the duty cycle of the 12V signal. It is compatible with almost all 12V brushed motors and 2/3-wire brushless fans.
We curate high-performance cooling solutions that are tested for reliability and safety. Find this PWM controller and a wide range of 12V fans at
