Description
The ebmpapst 414J/2HH (9291906015) is a professional-grade 24 V DC Axial Fan with compact dimensions of 40 x 40 x 25 mm, integrated with a dedicated Speed Signal (Tachometer) output for high-precision system monitoring. Engineered for the most demanding server environments and industrial drive systems, this unit features a 3-wire interface that allows real-time speed feedback to prevent critical component overheating. Driven by an electronically commutated external rotor motor with integrated auto-restart and reverse polarity protection, it provides a precise Max. Power Consumption of 3.6 W and a Max. Current Draw of 0.15 A at 24 V DC. Operating at an ultra-high rated speed of 13000 RPM, it delivers a robust airflow of 38.0 m³/h (22.4 CFM) with an impressive Max. Static Pressure of 360 Pa. Constructed with glass-fiber reinforced PBT plastic and precision ball bearings, this 50 g unit ensures maximum cooling density and mechanical reliability for integrated industrial switchgear systems at the end.
