Application
The Sunon KDE1209PTBX.13.MS.(2).B1930.AR.GN is engineered for 24/7 mission-critical applications that demand high airflow density and motor longevity. The MS (MagLev System) design significantly reduces internal friction and mechanical vibration, which is essential for medical diagnostic devices and high-precision laboratory equipment. Its high 4100 RPM speed allows it to overcome significant airflow resistance, making it ideal for cooling high-density server racks and industrial power converters. The 3-wire tachometer output provides critical real-time speed feedback, while the “Auto Restart” function ensures the fan autonomously attempts to spin up after any temporary mechanical blockage, preventing thermal runaway in unmonitored systems.
