DESCRIPTION

The AFB1224VHE-TC5F is a DC brushless axial flow fan designed for thermal management applications requiring reliable cooling performance. It operates at a rated voltage of 24 VDC with an operating range of 14.0 to 27.6 VDC, delivering a maximum air flow of 4.201 m³/min (148.356 CFM) at zero static pressure and a maximum air pressure of 15.296 mmH2O at zero airflow. The fan runs at 4000±10% RPM with low acoustic noise of 51.0 dB-A (maximum 55.0 dB-A) and features two ball bearings for extended durability, with a rated life expectancy of 70,000 hours of continuous operation at 40°C. The unit incorporates an open-collector frequency generator (FG) signal output for speed monitoring and includes locked rotor protection and polarity protection for safe operation. Its plastic frame and impeller (UL 94V-0 rated) with IP55 ingress protection make it suitable for industrial cooling, server equipment, and thermal management systems where compact size and reliable performance are essential.
