Description
The ebmpapst 4114N/2H3P-309 (9694300309) is a specialized 24 V DC Axial Fan with dimensions of 119 x 119 x 38 mm, meticulously engineered for precision thermal management in high-end Siemens drive systems and industrial electronics. This unit features a sophisticated 4-wire interface, including an integrated PWM speed control input and a speed signal (FG) output for real-time monitoring. Driven by an electronically commutated external rotor motor with auto-restart locked-rotor protection, it delivers a precise Max. Power Consumption of 22.0 W and a Max. Current Draw of 0.92 A at 24 V DC. Operating at a peak rated speed of 5000 RPM, it provides a high-velocity airflow of 285.0 m³/h (167.7 CFM) to maintain optimal temperature in high-power VFD cabinets. Constructed with a die-cast aluminum metal housing and a 5-blade glass-fiber reinforced plastic impeller with precision dual ball bearings, this 390 g unit ensures maximum cooling performance and long-term mechanical stability for integrated industrial switchgear systems at the end.
