12038VA-48R-GM-01 NMB 48VDC 0.90A 120x120x38mm Axial Fan

Description

The NMB 12038VA-48R-GM-01 is a high-performance DC axial cooling fan featuring a 120 x 120 x 38 mm frame constructed from UL 94V-0 rated black plastic. Operating at a nominal 48 VDC, this unit draws 0.90 A to deliver a maximum airflow of 243.6 CFM and a static pressure of 1.49 inH2O. The internal mechanism utilizes a dual ball bearing system to support a rotational speed of 6400 RPM while maintaining an operational life expectancy of 60,000 hours at 60 °C. The fan is equipped with a 3-wire interface providing power, ground, and a tachometer signal for precise speed monitoring, and includes integrated auto-restart and polarity protection.
