Important Notes:

1. This is a 4-wire PWM fan speed controller, designed exclusively for controlling 12V fans that support PWM speed regulation, such as many 12V four-wire chassis or CPU fans.

2. It cannot control 2-wire or 3-wire fans !!!

Features:

1. Constructed from premium materials for assured quality

2. Equipped with a switch for power disengagement

3. Refined aesthetic design

4. Simplified wiring configuration

5. Stable operational performance

Specifications:

Operating Voltage: DC 12V (compatible with 8-15V; ensure fan voltage alignment)

Fan Current: Not exceeding 3A (current limited by switch and connectors; may be expanded via separate power cable)

PCB Self-Consumption: <20mA without fan connected

PWM Signal Mode: 5V 25kHz

PWM Output Range: 0%-100%

Initial PWM Adjustment Range: 0%-60%

Input type: Red and black wires

Output interface model: 2510-4P staggered pinout, standard CPU/chassis fan socket, 2.54mm pin pitch

Functional description:

Ensure correct polarity and power supply voltage. Connect to power and fan for operation. Potentiometer fully counter-clockwise for off, fully clockwise for maximum output.

The separate small adjustable resistor on the board (for initial speed adjustment) regulates the fan's speed at startup.

Should the fan's speed change in the opposite direction to the adjustment, this indicates a reverse-sequence fan. In such cases, solder-bridge the (PF) setting point. Always disconnect power before performing this operation to prevent damage! After bridging, the PWM signal will change in the opposite direction to the adjustment, enabling forward regulation for reverse-sequence fans.
