The **W2CE-13B-R/UL** is a high-performance, AC axial fan manufactured by **Sanyo Denki** (SanAce series). It is designed for cooling industrial equipment, server racks, and power supplies. --- ### 1. Key Technical Specifications Below is a breakdown of the primary electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (50/60 Hz) | | **Power Consumption** | ~11W to 15W (depending on frequency) | | **Airflow** | ~48 to 60 CFM (Cubic Feet per Minute) | | **Static Pressure** | ~35 to 45 Pa | | **Noise Level** | ~36 to 40 dB(A) | | **Bearing Type** | Dual Ball Bearing | | **Safety Certifications** | UL, CSA, TUV | --- ### 2. Internal Electronic Components The "Electronic Parts" within this unit are relatively straightforward as it is an AC-powered induction motor fan rather than a DC brushless fan: * **Stator Windings:** High-quality copper coils designed to handle 230V AC input. These generate the electromagnetic field required to rotate the rotor. * **Capacitor-Run Motor:** In many AC fans of this size, an internal capacitor is used to create a phase shift in the windings to initiate and maintain rotation. * **Thermal Protection:** The "UL" designation implies the motor includes impedance protection or a thermal cutoff to prevent fire if the rotor is locked (impedance protected). * **Lead Wires:** Standard UL-rated insulated wires for connection to the AC power source. --- ### 3. Physical Construction * **Frame:** Die-cast aluminum. This acts as a heat sink for the motor and provides structural rigidity. * **Impeller (Blades):** Usually made of flame-retardant plastic (UL94V-0) or metal, depending on the specific revision. * **Dual Ball Bearings:** These provide a significantly longer lifespan (typically 40,000 to 60,000 hours) compared to sleeve bearings, especially in high-temperature environments. --- ### 4. Part Number Breakdown Understanding the nomenclature helps identify the electronic requirements: * **W2:** Series indicator for SanAce AC fans. * **CE:** Specific frame size/series (approx. 120mm x 120mm x 38mm). * **13:** Voltage code (1 = 100V, 2 = 200V, 3 = 230V). * **B:** Speed grade (typically stands for High Speed). * **R/UL:** Indicates RoHS compliance (R) and Underwriters Laboratories safety certification (UL).
