The **W2AC-A32A-R** is a specific part number typically associated with high-performance cooling solutions, most commonly identified as an **AC axial fan** manufactured by companies like **Wellington** or similar industrial cooling brands. Below is a breakdown of its electronic and mechanical specifications. --- ### 1. Technical Specifications The following table outlines the typical electrical and physical parameters for this series: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Current Rating** | ~0.14A - 0.22A (varies by load) | | **Power Consumption** | Approx. 30W - 40W | | **Speed (RPM)** | 2,500 - 2,900 RPM | | **Airflow** | ~90 - 110 CFM | | **Bearing Type** | Dual Ball Bearing (for longevity) | | **Termination** | Lead Wires or Terminals (R-suffix often denotes Lead Wires) | --- ### 2. Electronic Component Breakdown #### A. The Motor Structure * **Shaded Pole or Capacitor Run:** These fans generally use a permanent split capacitor (PSC) or a shaded-pole induction motor. These are chosen for their reliability in continuous-duty applications. * **Insulation Class:** Usually **Class B or F**, meaning the internal wiring can withstand temperatures up to 130°C–155°C without the insulation melting. #### B. Protection Features * **Impedance Protection:** The motor is designed so that if the fan blade is stalled (locked rotor), the internal resistance (impedance) prevents the coils from drawing enough current to catch fire. * **Thermal Cutoff:** Some variants include a thermal fuse that breaks the circuit if the internal temperature exceeds safety limits. #### C. Housing and Material * **Frame:** Die-cast aluminum (acts as a heat sink for the motor). * **Impeller:** Reinforced plastic (PBT) or metal, designed for aerodynamic efficiency and low noise (dB). --- ### 3. Common Applications Due to its AC power input and high durability, the W2AC-A32A-R is found in: 1. **Server Enclosures:** Providing exhaust for high-heat rack equipment. 2. **Industrial Control Panels:** Cooling PLCs and power supplies. 3. **Vending Machines:** Air circulation for refrigeration units. 4. **Medical Equipment:** Heat dissipation for diagnostic imaging machines. --- ### 4. Part Number Decoder (Typical) While manufacturers vary slightly, the code usually breaks down as follows: * **W2:** Series designation. * **AC:** Power type (Alternating Current). * **32:** Frame size indicator (e.g., 120mm x 120mm x 38mm). * **A:** High speed / Performance curve. * **R:** Rotation direction or "RoHS Compliant" / "Rear Lead" designation.
