Description
The NMB 4715VL-07W-B86-E51 is a very high-performance 48V DC axial cooling fan. Measuring 120mm x 120mm x 38mm, this fan is designed for extremely demanding thermal management applications, such as servers, telecom equipment, and power supplies, where maximum airflow and static pressure are critical. It operates at a rated current of 0.90A, consuming 43.2W of power. This powerful input enables it to achieve an exceptionally high rotational speed of 6950 RPM, generating a substantial airflow of 260 CFM and a high static pressure of 1.68 inch-H2O. Its noise level is 69 dBA, reflecting its high-performance nature. The fan features durable ball bearings for an extended operational lifespan of 100,000 hours at 25°C. This model commonly comes with 4-wire leads, typically providing power, ground, a tachometer output for speed monitoring, and PWM input for speed control.
