The **W2AC-A14C-R** is a specific model within the **W2AC series of AC Axial Fans**, typically manufactured by companies like **Wintek** or associated industrial cooling suppliers. These fans are designed for high-performance thermal management in electronic enclosures and industrial cabinets. --- ### 1. Technical Specifications Below are the primary electronic and physical specifications for the W2AC-A14C-R: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Current Consumption** | Approx. 0.14A - 0.22A (Model dependent) | | **Power Input** | ~30W - 38W | | **Bearing Type** | Dual Ball Bearing (indicated by 'B' or 'R' suffix) | | **Dimensions** | 172mm x 150mm x 51mm (Oval/Round shape) | | **Speed** | 2700 - 3000 RPM | | **Airflow** | ~190 - 235 CFM | | **Termination** | Lead Wires or Terminals | --- ### 2. Core Electronic Components The "Electronic Parts" of this fan consist of the motor assembly and internal protection circuitry: #### A. Shaded Pole or Capacitor-Run Motor * **Stator & Rotor:** It utilizes a permanent split capacitor (PSC) or shaded-pole AC induction motor. The stator contains copper windings that generate a rotating magnetic field when AC power is applied. * **Windings:** High-quality enameled copper wire rated for high temperatures (usually Class B or F insulation). #### B. Bearings (The "R" Suffix) * The **"R"** or suffix often denotes a specific revision or a **Ball Bearing** system. Ball bearings are electronic-grade mechanical parts that allow the fan to operate at high temperatures (up to 70°C) with a long lifespan (L10 life of ~50,000 hours). #### C. Protection Circuitry * **Impedance Protection:** The motor windings are designed so that if the fan blade is locked (stalled), the impedance of the coils limits the current flow to prevent the wires from melting or catching fire. * **Thermal Cut-off (Optional):** Some variants include a thermal fuse that breaks the circuit if the internal temperature exceeds a safe threshold. --- ### 3. Part Number Decoder While manufacturer codes vary slightly, the breakdown for the W2AC series generally follows this logic: 1. **W2AC:** Series designation (AC Axial Fan). 2. **A14:** Size/Performance code (specifically the 172mm class). 3. **C:** Voltage code (typically 220-240V). 4. **R:** Often indicates **RoHS Compliance** or a specific **Bearing/Rotation** orientation. --- ### 4. Application Use-Cases * **Server Racks:** Cooling high-density computing equipment. * **Industrial Control Panels:** Preventing overheating in PLCs and VFDs. * **Power Supplies:** Large-scale rectifiers or inverters.
