Description
The NMB 3110RL-05W-S79-C04 is a high-performance 24 VDC industrial DC axial fan with dimensions of 80 x 80 x 25 mm, engineered for continuous thermal regulation in demanding environments. This unit utilizes a precision-engineered 7-blade impeller driven by a brushless DC motor, which maintains a powerful 5.76 W power profile for efficient air displacement. Its structural integrity is anchored by a reinforced thermoplastic frame and a premium dual ball bearing system, ensuring exceptional mechanical longevity. The 3-wire configuration provides a dedicated Speed Sensor (FG) signal, offering a robust and modular electrical connection ideal for high-reliability systems such as industrial power supplies, telecommunications infrastructure, and automated control systems.
