Description
NMB 4715KL-07W-B49-P03 is a 48VDC 120x120x38mm Axial Fan optimized for high-density thermal management in elevator inverter systems. This unit features a dual ball bearing architecture and a brushless DC motor design, ensuring low thermal impedance and high structural rigidity under continuous duty cycles. Engineered with a 7-blade aerodynamic profile, it delivers a rated current of 0.26A and a rotational speed of 3300 RPM to maintain critical airflow across power electronics. The integration of a third-wire tachometer signal allows for precise monitoring of cooling performance, making it an essential component for preventing thermal throttling in Hitachi CA13 series drive controllers.
