SANYO San Ace 40 9HVA0412P3J001 Product Full English Introduction
1. Product Overview
The 9HVA0412P3J001 is a high-performance 40×40×28mm DC axial cooling fan from SANYO DENKI’s classic San Ace 40 series, engineered for extreme high-static-pressure heat dissipation scenarios. Featuring an ultra-high rated speed of 38000 RPM, this fan delivers powerful airflow and massive static pressure to push air through dense heat sinks, tight chassis and high-resistance cooling channels. Equipped with built-in PWM speed regulation and pulse tachometer sensor, it supports real-time fan speed monitoring and flexible speed adjustment, perfectly matching thermal management demands of high-power industrial hardware. All units comply with UL, CSA, EN and RoHS directives for global industrial deployment.

3. Core Product Advantages
-
Ultra High Static Pressure & Rotation Speed
38000 RPM top-tier rotation speed creates up to 2300Pa static pressure, capable of penetrating thick heat sinks, dense PCB layouts and narrow ventilation ducts, solving heat dissipation bottlenecks for high-heat-density equipment.
-
Dual PWM & Pulse Feedback Function
Integrated PWM speed control enables dynamic fan speed adjustment based on equipment temperature to cut idle noise and power consumption; built-in pulse sensor transmits real-time rotational speed signals to host controllers for fan fault detection and status monitoring.
-
Wide Operating Temperature & Long Service Life
Stable performance from -20℃ to 70℃, with a rated lifespan of 300,000 hours under 60℃ working environment, minimizing maintenance frequency for continuous-operation industrial devices.
-
Global Standard Certifications
Passed UL safety rating, CSA, EN European standards and RoHS environmental directive, applicable for export equipment sold to North America, Europe and worldwide markets.
-
Ribbed Reinforced Frame
Optimized ribbed plastic frame enhances structural rigidity, reduces vibration during high-speed operation and improves overall operational stability.
4. Typical Application Scenarios
-
AI servers, high-density computing rack servers
-
Medical imaging equipment (CT, MRI, diagnostic devices)
-
Industrial servo amplifiers & high-power power supply modules
-
Chip mounters, semiconductor manufacturing equipment
-
Network switches, high-frequency communication base stations
-
High-performance industrial automation control hardware
