SANYO DENKI San Ace 38 High-Performance DC Fan – 9HVA0312P3K0011 | 38x28mm, 12V, 38,500 RPM, 2100Pa Static Pressure, PWM Control
Product Overview
The SANYO DENKI 9HVA0312P3K0011 is a premium member of the San Ace 38 series, engineered for applications requiring extreme cooling performance in compact spaces. Unlike standard cooling fans, this model operates at a high speed of 38,500 RPM, delivering an exceptional static pressure of 2,100 Pa (8.40 inchH₂O) and an airflow of 0.91 m³/min (32.2 CFM).
Designed with a robust plastic frame and impeller, it features advanced PWM (Pulse Width Modulation) speed control and a pulse sensor for real-time monitoring. This makes it the ideal solution for high-density electronic equipment, industrial lasers, and specialized machinery where overcoming high air resistance is critical.
Note: Due to its high-performance nature, this fan operates at 69 dB(A). It is recommended for industrial environments or enclosed systems where noise isolation is managed.

Applications
This high-static-pressure fan is specifically designed for:
-
Industrial Laser Cooling: Efficiently dissipating heat from high-power laser diodes.
-
High-Density Servers & Racks: Overcoming airflow resistance in tightly packed server blades.
-
3D Printing & CNC Machines: Cooling hotends and control boards in enclosed chambers.
-
Telecommunications Base Stations: Ensuring reliability in harsh outdoor cabinets.
-
Medical Imaging Equipment: Providing consistent cooling for X-ray and MRI components.
-
Projection Systems: Managing heat in high-lumen projectors.
Wiring & Connection Guide
The 9HVA0312P3K0011 utilizes a standard 4-wire interface:
-
Red Wire: Power Supply (+12V)
-
Black Wire: Ground (GND)
-
Yellow Wire: Pulse Sensor Output (Open collector output, 2 pulses per revolution)
-
Blue Wire: PWM Control Input (Frequency: 25kHz typical)
Connection Tip: Ensure the PWM control signal frequency matches the fan specification (typically 25kHz) for stable operation. The fan will run at full speed if the PWM wire is left open or pulled high, depending on the specific controller logic.
