The **W2CE-5C1-R2/Q** is a specific variant of an industrial-grade **AC Axial Fan**, typically manufactured by brands like **Fulltech** or similar industrial cooling solution providers. These fans are designed for high-performance cooling in server racks, control cabinets, and industrial machinery. Below is a breakdown of its electronic and physical specifications. --- ## 1. Technical Specifications The "W2CE" series represents a standard 120mm x 120mm x 38mm form factor, which is the industry standard for high-airflow cooling. | Feature | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (typically 220V–240V range) | | **Frequency** | 50 / 60 Hz | | **Current / Power** | ~0.14A / 20W - 30W (varies by load) | | **Speed** | 2600 – 3000 RPM | | **Airflow** | ~90 – 105 CFM (Cubic Feet per Minute) | | **Noise Level** | 40 – 48 dB(A) | | **Bearing Type** | Dual Ball Bearing | | **Connection** | Terminals or Lead Wires (R2/Q usually denotes Terminal) | --- ## 2. Key Electronic Components ### A. The Shaded Pole Motor The fan utilizes an **AC Induction Motor**, specifically a "Shaded Pole" design. * **Self-Starting:** It does not require a start capacitor, making the internal circuitry simpler and more robust against heat. * **Impedance Protection:** The motor is "Impedance Protected" (often labeled as **Z.P.**). This means the motor is designed so that if the blades are blocked (stalled), the internal resistance prevents the coils from burning out immediately. ### B. Bearing System (Dual Ball) The "2B" or "Ball" designation implies a high-quality mechanical assembly. * **Longevity:** Rated for approximately 50,000 to 70,000 hours of continuous use. * **Mounting:** Can be mounted in any orientation (horizontal, vertical, or angled) without affecting the lifespan, unlike sleeve bearings. ### C. Housing and Insulation * **Frame:** Typically Die-cast Aluminum (painted black) for heat dissipation and EMI shielding. * **Impeller:** Reinforced plastic (PBT) or metal, UL 94V-0 rated for flame retardancy. * **Dielectric Strength:** Usually tested to withstand 1500V AC for 1 minute between the frame and the terminals. --- ## 3. Part Number Suffix Decoding While coding varies by manufacturer, the **R2/Q** suffix generally refers to: * **R2:** Often indicates a specific revision or a high-speed (High RPM) winding configuration. * **Q:** Often stands for **Quick-connect terminals** (metal tabs) rather than pre-stripped lead wires. This allows for easier maintenance and modular wiring in industrial panels. --- ## 4. Usage Considerations * **Environment:** Rated for temperatures between -20°C to +70°C. * **Safety Standards:** Usually carries UL, CE, and TUV certifications. * **Application:** Best suited for power supplies, welding machines, and telecommunications enclosures where 230V mains power is readily available.
