Description
The NMB 4715KL-05W-B39-E00 is a high-performance DC Axial Fan with dimensions of 119 x 119 x 38 mm. It operates on a 24 VDC nominal voltage and draws an updated, higher rated current of 0.40 A, resulting in 9.6 W of input power. This high-speed model achieves an estimated speed of 3300 RPM, delivering an estimated maximum airflow of 212.4 m3/h (125 CFM) and an estimated maximum static pressure of 84.7 Pa (0.34 inAq). Utilizing a robust Dual Ball Bearing system and featuring a 3-Wire termination, it typically includes a Tachometer (Pulse Sensor) for real-time speed monitoring. This powerful and monitored fan is designed for high-end server, storage, and industrial cooling applications where maximum airflow and continuous performance monitoring in a standard 120 mm frame are critical.
