Description
The ebmpapst 4114N/2H8PU is an ultra-high-performance 24 VDC DC Axial Fan with dimensions of 119 x 119 x 38 mm, specifically engineered for extreme thermal management in industrial frequency converters and high-density electrical control cabinets. Driven by a specialized brushless DC motor with integrated electronic protection and PWM speed control, this unit provides a massive power consumption of 120 W and a nominal current of 5.0 A at 24 VDC. Operating at an extraordinary rated speed of 11,000 RPM, it delivers a superior airflow for critical heat extraction. Constructed with a die-cast aluminum metal housing and a 5-blade high-strength plastic impeller featuring a precision ball bearing system, this 0.425 kg unit provides a robust air-moving solution with a noise level of 78 dB(A) and IP20 protection, ensuring maximum cooling performance and long-term mechanical stability for high-power inverters, variable frequency drives (VFD), and high-performance server systems at the end.
