The **W2CE-5C1-R/UL** is a specific model of an AC axial fan manufactured by **Sanyo Denki**, part of their "San Ace" series. These fans are designed for high-reliability cooling in industrial equipment and server racks. Below is a breakdown of its electronic and mechanical specifications. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Input Voltage** | 200V / 230V AC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | Approx. 14W to 18W | | **Dimensions** | 120mm x 120mm x 38mm | | **Bearing Type** | Dual Ball Bearing | | **Frame Material** | Aluminum Die-cast | | **Impeller Material** | Plastic (UL 94V-0) | | **Safety Certification** | UL (Underwriters Laboratories) Recognized | --- ### 2. Key Electronic Characteristics #### Motor Design The "W" in the series often denotes a **Shaded Pole Motor** or a **Capacitor-Run Induction Motor** (depending on the specific sub-series). In AC fans, these motors are brushless by design, utilizing the AC frequency to rotate the magnetic field. #### Termination The **"R"** suffix typically indicates that the fan uses **Lead Wires** for electrical connection rather than terminal pins. This allows for easier soldering or crimping into custom wiring harnesses. #### Protection Mechanism * **Burnout Protection:** These fans usually feature impedance protection or thermal protection. This means that if the rotor is locked (e.g., something gets stuck in the blades), the motor is designed to limit the temperature rise to prevent fire or melting. * **Insulation Resistance:** Rated for 10MΩ or higher at 500V DC between the lead wires and the frame. --- ### 3. Performance Data | Metric | Value (at 60Hz) | | :--- | :--- | | **Airflow** | ~100 - 105 CFM | | **Static Pressure** | ~0.25 - 0.30 inH₂O | | **Noise Level** | ~40 - 45 dB(A) | | **Expected Life** | 25,000 to 40,000 Hours (at 60°C) | --- ### 4. Application Areas Due to its rugged aluminum construction and high voltage rating (200-230V), this part is commonly found in: 1. **Industrial Control Panels:** Cooling PLCs and power supplies. 2. **Server Cabinets:** For high-density heat dissipation. 3. **Medical Equipment:** Reliable long-term cooling for diagnostic machines. 4. **Power Inverters:** Used in large-scale solar or wind power conversions. ---
