5. Core Product Features & Advantages
5.1 PWM Intelligent Speed Regulation
The fan integrates independent PWM control circuit. Users can adjust the fan rotation speed according to the real-time load of equipment. It effectively reduces power consumption and operating noise under low load conditions, realizing energy-saving intelligent heat dissipation.
5.2 Real-time Pulse Speed Monitoring Sensor
Equipped with pulse output sensor, the host system can continuously read real-time fan speed data. It supports automatic abnormal alarm when the fan stalls or fails, greatly improving the operation safety of critical IT and medical equipment.
5.3 Dual-layer Built-in Motor Safety Protection
Two protection mechanisms prevent permanent motor damage:
-
Locked rotor burnout protection: Automatically cut off the current when the fan impeller is blocked by foreign objects;
-
Reverse polarity protection: The fan will not be damaged if the positive and negative power wires are connected reversely by mistake.
5.4 Ribless Frame Design for Flexible 1U Assembly
Adopts ribless smooth plastic frame, which reduces internal space occupation inside compact 1U chassis, avoids vibration resonance interference, and matches the standard mounting hole size of most 1U servers, network switches and embedded power supplies.
5.5 Long L10 Service Life & Wide Temperature Adaptability
High-precision bearing system is adopted, with L10 service life up to 30000 hours under 60℃ continuous operation. Stable operation can be guaranteed within -20℃ ~ +60℃ wide temperature range, adapting to complex industrial working environments.
5.6 UL94V-0 Flame Retardant Material & Full Global Certifications
Both frame and impeller are made of UL94V-0 flame retardant plastic to meet strict industrial fire safety standards. The fan has passed UL, CSA, EN and RoHS certifications, fully meeting the export standards of North America, Europe and other global regions.
