The **W2CE-1BD-R/UL** is a high-performance **AC Axial Fan** manufactured by **World Fans**. These fans are specifically designed for cooling electronic cabinets, server racks, and industrial machinery where high airflow and durability are required. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the W2CE-1BD-R/UL: | Characteristic | Specification | | :--- | :--- | | **Input Voltage** | 115V AC | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | ~0.25 A (Subject to load) | | **Input Power** | ~20 - 30 Watts | | **Speed (RPM)** | High Speed (approx. 2700 - 3100 RPM) | | **Airflow Capacity** | ~100 - 110 CFM | | **Bearing Type** | Dual Ball Bearing | | **Safety Certification** | UL (Underwriters Laboratories) Recognized | --- ### 2. Electronic & Material Components * **Motor Design:** It utilizes a **Shaded Pole Motor** or a **Permanent Split Capacitor (PSC)** design. These motors are brushless and induction-based, providing long-term reliability without the wear-and-tear of brushes. * **Bearing System:** The "BD" in the suffix typically denotes **Ball Bearings**. Compared to sleeve bearings, ball bearings allow the fan to be mounted in any orientation (horizontal or vertical) and offer a significantly higher MTBF (Mean Time Between Failures). * **Housing & Impeller:** The frame is usually made of **Die-cast Aluminum**, which acts as a heat sink for the motor, while the impeller (blades) is made of reinforced thermoplastic (PBT) to reduce weight and noise. * **Termination:** Usually features lead wires or terminal lugs for direct connection to AC power sources. * **Thermal Protection:** The "R" often signifies **Impedance Protection** or **Thermal Protection**, ensuring the motor does not catch fire or melt if the blades are accidentally locked (stalled). --- ### 3. Usage & Environmental Ratings * **UL/cUL Listed:** The "/UL" suffix indicates it has passed rigorous safety standards for the North American market regarding electrical insulation and fire safety. * **Operating Temperature:** Typically rated for operation between **-10°C to +70°C**. * **Applications:** * Industrial Control Panels. * UPS (Uninterruptible Power Supplies). * Telecommunication Racks. * Medical Equipment. --- ### 4.
