424J/2HP ebmpapst 24V 0.28A 40x40x28mm DC Axial Fan

Description

The ebmpapst 424J/2HP (Part No. 9291908006) is an ultra-high-performance 24 VDC axial fan from the S-Panther series, specifically engineered for intense thermal management in space-constrained electronic environments. Driven by a sophisticated 4-wire interface, this unit is part of the VWCE040JJDES series and delivers a powerful airflow at a rated speed of 17250 RPM. Operating with a nominal current of 0.28 A and a power consumption of 6.9 W, it generates significant static pressure of 530 Pa, making it ideal for cooling high-density server blades and compact power modules. The robust design features glass-fiber reinforced plastic housing and impellers, combined with premium ball bearings to ensure durability under extreme high-speed operation. The 424J/2HP provides professional-grade precision cooling with PWM speed control and Tacho feedback across a wide DC voltage range of 16-26.4 V.
