## Overview of W2PE-50D-R/UL The **W2PE-50D-R/UL** is a high-performance industrial cooling fan manufactured by **Wibond** (often associated with specialized cooling solutions). It is designed for thermal management in server racks, industrial control panels, and power supplies where high airflow and reliability are critical. --- ### Technical Specifications The following table summarizes the primary electronic and mechanical characteristics of the unit: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | ~30W - 40W (Model dependent) | | **Speed** | High-speed (Typically 2500 - 3000 RPM) | | **Bearing Type** | Dual Ball Bearing | | **Certification** | UL Recognized (E-file standards) / CE | | **Housing Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic (PBT) / UL 94V-0 Rated | --- ### Key Electronic Components & Features #### 1. Shaded Pole or Capacitor-Run Motor The unit typically utilizes a **Single Phase AC Motor**. * **Winding Insulation:** Class B or Class F insulation to handle high temperatures. * **Protection:** Impedance protected or thermally protected to prevent burnout if the rotor is locked. #### 2. Dual Ball Bearing System Unlike sleeve bearings, the "R" designation often implies a robust bearing system designed for: * **Longevity:** L10 life expectancy of approximately 50,000 to 70,000 hours. * **Mounting:** Can be mounted in any orientation (horizontal, vertical, or angled) without losing efficiency. #### 3. Lead Wire / Termination The **"UL"** suffix indicates that the wiring and internal components meet Underwriters Laboratories safety standards. * **Wires:** Typically 22 AWG or 24 AWG, UL1007 or UL1015 rated. * **EMI Suppression:** Often includes internal circuitry to minimize electromagnetic interference with neighboring sensitive electronics. #### 4. Safety and Environmental Features * **Dielectric Strength:** Tested to withstand high AC voltage (usually 1500V AC for 1 minute) between the frame and terminals. * **RoHS Compliance:** Free from hazardous substances like Lead and Mercury. --- ### Application Use Cases 1. **Server Enclosures:** Constant high-volume air exchange. 2. **CNC Machinery:** Cooling the electronic control boards and spindles. 3. **UPS Systems:** Dissipating heat from large power transformers and capacitors.
