SANYO DENKI San Ace 38 Long-Life DC Fan – 9HVA0312P3G0011 | 38x28mm, 12V, 30,000 RPM, Non-Ribbed Design, PWM & Pulse Sensor
Product Overview
The SANYO DENKI 9HVA0312P3G0011 is a refined variant of the San Ace 38 series, engineered for applications prioritizing longevity, moderate airflow, and reduced mechanical complexity. Operating at 30,000 RPM, it delivers 0.71 m3/min (25.1 CFM) airflow and 1,300 Pa (5.20 inchH?O) static pressure — sufficient for most enclosed industrial enclosures without excessive noise or vibration.
Unlike ribbed-frame models, this unit features a smooth plastic frame (Ribbed: No), which simplifies cleaning and reduces dust accumulation in sensitive environments. Equipped with PWM speed control and a pulse sensor, it enables intelligent thermal management and real-time diagnostics. With an expected life of 70,000 hours at 40°C, it offers exceptional reliability for continuous-operation systems.
Note: Sound level is rated at 64 dB(A) — suitable for office-adjacent industrial zones or equipment rooms where moderate acoustics are acceptable.
Key Features
-
Extended Service Life: Rated for 70,000 hours at 40°C — among the highest in its class for compact fans.
-
Non-Ribbed Frame: Smooth exterior minimizes dust trapping and eases maintenance in cleanroom or medical settings.
-
Precision Speed Control: PWM interface allows dynamic adjustment from idle to full speed based on thermal load.
-

Applications
This model is particularly suited for:
-
Medical Diagnostic Equipment: Where smooth surfaces reduce contamination risk.
-
Laboratory Instruments: Analyzers, centrifuges, and incubators requiring stable, long-term cooling.
-
Office Automation Systems: High-end printers, scanners, and copiers needing reliable but quiet operation.
-
Telecom Infrastructure: Base station controllers and network switches operating 24/7.
-
Audio/Video Production Gear: Broadcast consoles and editing workstations where acoustic comfort matters.
-
Industrial IoT Gateways: Compact edge devices requiring durable, low-maintenance cooling.
Wiring & Connection Guide
Standard 4-wire configuration:
-
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: Ensure PWM signal source matches fan’s expected frequency range. Leaving PWM pin floating may result in default full-speed operation depending on system design.
