New Original Delta PFB1224UHEC8X PN‑406345 REV 06 DC Brushless Cooling Fan
Product Overview
This is an original Delta PFB1224UHEC8X (PN‑406345 REV 06) high‑performance axial DC brushless cooling fan from the PFB product series. It adopts dual‑ball‑bearing structure and runs on 24 VDC power supply, with standard 120×120×38 mm industrial frame size. It delivers ultra‑high airflow and extreme static‑pressure performance, specially engineered for heavy‑duty heat‑dissipation scenarios. Widely applied for high‑power inverters, servo power units, industrial cabinet, charging equipment, power supply modules and other high‑heat‑generation electronic assemblies. It supports long‑term continuous operation under severe industrial workshop conditions, with locked‑rotor protection to prevent motor burnout when fan blades are blocked。
Main Functions
- Deliver powerful forced‑air convection cooling to dissipate heat for high‑power industrial electronic equipment.
- Built‑in locked‑rotor protection function: cut off power automatically when fan stalls, avoid motor damage.
- Stable constant‑speed operation under rated 24 VDC input, maintain consistent high airflow and static pressure.
- 2‑wire lead‑wire output for simple power connection, suitable for direct power‑driven installation.
- Standard mounting hole layout for easy installation on cabinet panels, chassis and equipment housings.
- Adapt to equipment with filter screens and dense internal baffles by virtue of high static‑pressure capability.
Technical Features
- Dual ball‑bearing design, long MTBF lifetime, reliable for non‑stop long‑time running in vibration‑prone industrial environment.
- High‑speed rotation, ultra‑large airflow and outstanding static‑pressure performance for heavy‑duty cooling demand.
- Brushless DC motor reduces mechanical abrasion and extends service cycle.
- Frame and impeller adopt UL94V‑0 flame‑retardant reinforced plastic, anti‑aging and impact‑resistant.
- Wide operating voltage tolerance range adapts to unstable industrial DC power supply.
- Support reverse‑connection protection, avoid damage caused by positive‑negative polarity mis‑wiring.
- Comply with UL, CE, VDE, RoHS international certification standards.
