Description
The ebm-papst 4112N/2H6P is an ultra-high-performance, industrial-grade DC axial compact fan engineered for extreme thermal management applications. Operating at a nominal voltage of 12 VDC, this heavy-duty 119x119x38 mm (12038 frame size) fan delivers an extraordinary 63 Watts of cooling power, driving a maximum rated speed of 8,400 RPM under full load.
Designed for mission-critical systems with high static backpressure, it features a robust 4-wire interface supporting intelligent speed signaling and precise PWM speed control. With a massive peak starting current capability of 7.8 A (7,800 mA) and heavy-duty dual ball bearings, this fan is the definitive cooling solution for high-density servers, telecommunications enclosures, and demanding industrial inverters.
