2. Core Product Performance Advantages
2.1 Ultra Low Power Consumption Design
Compared with high-speed 4028 fan models of the same San Ace series, the 9GA0412P3M011 only consumes 2.52 W rated power, rated current limited to 0.21 A. Optimized internal motor winding reduces idle power loss significantly, cutting long-term equipment energy consumption for 24-hour continuous operation devices. It is labeled as SANYO DENKI Eco Products to meet global energy-saving standards for electronic equipment.
2.2 Low Noise Operation with Stable Heat Dissipation
The rated speed of 12500 min-1 delivers balanced airflow and wind pressure while controlling sound pressure level at only 47 dB(A). It avoids excessive high-frequency noise generated by ultra-high speed fans, perfectly matching equipment that requires quiet operating environment such as office industrial switches and portable test instruments. The maximum airflow reaches 0.46 m3/min and max static pressure hits 258 Pa, capable of heat dissipation for small heat sinks and narrow air channels.
2.3 PWM Speed Regulation & Pulse Speed Feedback
Built-in standard PWM speed control function allows users to adjust fan running speed dynamically based on internal equipment temperature. Lower rotating speed under light load further reduces power consumption and running noise. The embedded pulse sensor transmits real-time rotational speed signals to the main control board, supporting closed-loop temperature monitoring, stall protection and abnormal speed fault alarm functions.
2.4 Wide Temperature Adaptability & Long Service Life
The fan can operate stably from -20 ℃ to +70 ℃, adapting to low-temperature factory workshops and continuous high-load indoor working conditions. Reliable bearing structure ensures 40000 hours service life under 60 ℃ continuous operation and up to 70000 hours service life under 40 ℃, lowering later maintenance and fan replacement frequency for industrial devices.
2.5 Complete International Certifications
The fan passes UL safety rating, CSA electrical standard certification, EN European equipment standard certification and RoHS hazardous substance restriction directive. It fully meets export compliance requirements for electronic cooling products sold to Europe, North America and other global regions.

5. Installation and Operation Guidelines
-
Keep fan input DC voltage within the range of 10.8 V to 13.2 V. Long-term operation beyond this voltage interval will cause abnormal speed fluctuation and shorten service life.
-
When using PWM speed regulation, align the signal voltage level with the host mainboard to guarantee normal speed adjustment and stable pulse signal output.
-
Avoid installation environment with heavy dust, oil mist or corrosive gas. Additional dust-proof and waterproof housing needs to be configured separately for harsh working conditions.
-
Service life data is measured under standard laboratory environment. Continuous operation at the upper temperature limit of 70 ℃ will reduce the actual usable lifespan of the fan.
-
Do not block fan air inlet and outlet during installation, reserve enough ventilation space to maintain rated airflow and static pressure performance.
