The **W2AC-A2DY-R** is a specific part number typically associated with professional-grade electrical components, specifically within the realm of **AC Axial Fans** or thermal management modules (often manufactured by brands like Delta Electronics or specialized industrial suppliers). Below is a detailed breakdown of the electronic parts and specifications associated with this component type. --- ### 1. General Specifications This part is an AC-powered axial fan designed for cooling electronic enclosures, server racks, or industrial machinery. | Parameter | Typical Value / Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Current Consumption** | ~0.10A to 0.15A (varies by load) | | **Bearing Type** | Dual Ball Bearing (indicated by "B" or "2" in mid-strings) | | **Frame Material** | Die-cast Aluminum (Ruggedized) | | **Impeller Material** | Thermoplastic (UL 94V-0 rated) | --- ### 2. Key Electronic Components & Construction The internal circuitry of the W2AC-A2DY-R consists of several critical electronic sub-parts: #### A. The Induction Motor * **Shaded Pole or Capacitor Run:** Most AC fans of this series use a shaded-pole induction motor. It consists of a copper winding (stator) and a squirrel-cage rotor. * **Windings:** High-purity copper wire with Class B or Class F insulation to withstand high temperatures. #### B. Protection Circuitry * **Impedance Protection:** The motor is designed so that if the fan blade is stalled (locked rotor), the internal resistance (impedance) of the windings prevents the current from rising to a level that would cause a fire. * **Thermal Cut-off (Optional):** Some variants include a thermal fuse that breaks the circuit if internal temperatures exceed safe limits (usually >110°C). #### C. Connection Interface * **Terminals vs. Leads:** The "R" suffix often denotes the termination style. In this series, it usually refers to **Terminals** (spade connectors) rather than stripped wires, allowing for quick disconnects. --- ### 3. Part Number Decoder (Typical) While naming conventions vary slightly by manufacturer, the code usually breaks down as follows: | Code Segment | Meaning | | :--- | :--- | | **W2** | Frame Size (e.g., 120mm x 120mm x 38mm) | | **AC** | Power Input Type (Alternating Current) | | **A2** | Voltage Rating (200V-240V range) | | **DY** | Speed/Performance Grade (High Airflow) | | **R** | Specific feature (e.g., RoHS compliant or Terminal-type) | --- ### 4. Technical Drawing & Integration To integrate this part into a system, engineers typically use the following pinout/connection logic: ```yaml Connection: L (Line): Connect to AC Live (Brown/Black) N (Neutral): Connect to AC Neutral (Blue/White) Earth: Grounding screw on the aluminum frame ``` ---
