4. Core Functional Features & Advantages
4.1 PWM Adjustable Speed Control
The fan integrates dedicated PWM control circuit. Users can adjust fan rotating speed via external PWM signal. It effectively reduces power consumption and operating noise under low-load equipment status, realizing intelligent energy-saving heat dissipation.
4.2 Real-time Pulse Speed Monitoring Sensor
Equipped with pulse output sensor, the host system can read real-time fan speed signal continuously. It supports abnormal alarm when fan stalls or malfunctions, improving equipment operation safety for critical IT and medical devices.
4.3 Dual Motor Built-in Protection
Two layers of motor protection avoid permanent damage:
-
Locked rotor burnout protection: Automatically cut off current when impeller is blocked;
-
Reverse polarity protection: No damage when positive/negative wires are connected reversely by mistake.
4.4 Ribbed Frame for 1U Rack Application
Specially designed ribbed plastic frame improves structural rigidity during installation inside narrow 1U chassis, reduces vibration resonance, and fits standard 1U server, switch and embedded power supply mounting holes perfectly.
4.5 Long L10 Service Life & Wide Temperature Adaptability
Adopt high-quality bearing system with L10 life up to 30000 hours at 60℃ working environment. Stable operation is guaranteed within -20℃ ~ +60℃ wide temperature range, suitable for industrial harsh working conditions.
4.6 Flame Retardant & Global Standard Certifications
Frame and impeller adopt UL94V-0 flame retardant plastic material. The fan passes UL, CSA, EN and RoHS certification, fully compliant with export standards for North America, Europe and global industrial equipment.
