Product Title
SANYO DENKI San Ace 38 Low-Power DC Fan – 9GA0312P3K0011 | 38x28mm, 12V, 7.4W, Smooth Frame, Quiet Operation, PWM & Pulse Sensor
Product Overview
The SANYO DENKI 9GA0312P3K0011 is a specialized variant of the San Ace 38 Low Power series, engineered for applications where energy efficiency, acoustic comfort, and surface cleanliness are critical. Operating at 25,000 RPM, it consumes only 7.4 Watts while delivering 0.6 m³/min (21.2 CFM) airflow and 800 Pa (3.21 inchH₂O) static pressure — ideal for general ventilation in enclosed electronics without excessive heat or noise generation.
Its defining feature is the smooth, non-ribbed plastic frame (Ribbed: No), which minimizes dust accumulation and simplifies cleaning — making it uniquely suited for hygienic environments such as medical devices, laboratories, and food-grade equipment. Equipped with PWM speed control and a pulse sensor, this fan enables intelligent thermal management and real-time diagnostics.
With a sound level of 59 dB(A) and official Eco Product certification, it supports sustainable design goals while ensuring user comfort in shared or sensitive spaces.

Applications
This low-power, smooth-frame fan is optimized for:
-
Medical Devices: Patient monitors, infusion pumps, surgical tools — where hygiene and silence are mandatory.
-
Laboratory Equipment: Centrifuges, analyzers, incubators — requiring particle-free operation.
-
Food & Beverage Processing: Packaging machines, refrigeration units — needing washable, non-porous surfaces.
-
Consumer Electronics: High-end audio gear, smart home hubs, VR headsets — prioritizing quiet, sleek design.
-
Retail Kiosks & Digital Signage: Interactive displays in malls or airports — where aesthetics and acoustics matter.
-

Wiring & Connection Guide
Standard 4-wire interface:
-
Red Wire: +12V Power Input
-
Black Wire: Ground (GND)
-
Yellow Wire: Pulse Sensor Output (Open collector, 2 pulses per revolution)
-
Blue Wire: PWM Control Input (Typical frequency: 25kHz)
Installation Note: For optimal energy savings, configure PWM duty cycle based on actual thermal load. Leaving PWM pin open may result in full-speed operation depending on controller logic.
