DC5525 12V Fan Speed Controller, for 2/3/4 wire fans, voltage speed regulation (non-PWM), stepless speed from 0 to 100%, with overcurrent protection

Wide Compatibility and Easy Connection Supports 2-wire, 3-wire, and 4-wire DC fans equipped with multiple interfaces, including 3-pin MX2.54, 2-pin XH2.54, and PH2.0. Pure copper interfaces ensure excellent conductivity, and the KF301 output terminal meets your various DIY connection needs for scenarios ranging from PC case cooling to industrial control cabinets.

Voltage Regulation Speed Control, Non-PWM Important Note: This controller adjusts speed by regulating voltage, not via PWM (Pulse Width Modulation). It is fully compatible with fans with 4 wires (connect their power wires), allowing stepless speed regulation from 0 to 100% within a voltage range of 1.25V to 12.5V MAX, providing a stable and reliable fan control solution. Stable performance and safety assurance: Utilizes a high-quality XLSEMI main chip, offering high output current capacity, low ripple noise, and excellent line/load regulation. Built-in output overcurrent protection effectively safeguards against accidental short circuits or overloads, ensuring stable operation. long-term for your equipment and controller.

Precise control, perfect balance. Enjoy easy and continuous fan speed adjustment thanks to precise voltage regulation, finding the perfect balance between efficient cooling and quiet operation. Ideal for optimizing airflow in computer cases or managing the cooling of various work equipment.

Plug and Play, DIY Friendly. Features a wide range of 12V DC input using a standard 5.5 x 2.5 mm power plug.
