The **W2AC-AC3A-R2** is a specific model identifier typically associated with high-performance cooling solutions, most commonly manufactured by companies like **Wintech** or **Delta Electronics** for industrial and server applications. Below is the technical breakdown of its electronic components and specifications. --- ### 1. Technical Specifications This part is an AC axial fan designed for thermal management in enclosures, server racks, or industrial machinery. | Feature | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Power Consumption** | ~20W - 30W (model dependent) | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Housing Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic (PBT) or Steel | | **Termination** | Lead Wires (R2 designation usually implies specific wire length/connector) | --- ### 2. Core Electronic Components The device consists of several critical sub-components that manage its rotation and safety: * **Induction Motor:** Uses a shaded-pole or capacitor-run motor (depending on the exact sub-series) to convert AC current into mechanical rotation. * **Thermal Protector:** An internal thermal fuse or impedance protection that prevents the motor from catching fire if the blades are obstructed (locked rotor). * **Dual Ball Bearings:** High-precision electronic-grade bearings designed to handle high RPMs (3000+) and provide an MTBF (Mean Time Between Failure) of roughly 50,000 hours. * **Stator Windings:** High-purity copper coils insulated with Class B or Class F materials to withstand heat. --- ### 3. Part Number Decoding (W2AC-AC3A-R2) While manufacturers vary slightly, the nomenclature usually follows this logic: | Segment | Meaning | | :--- | :--- | | **W2AC** | Series designation (AC Axial Fan) | | **AC3A** | Dimensional code (likely 120mm x 120mm x 38mm) | | **R2** | Revision code or specific electrical lead/connector configuration | --- ### 4. Implementation Example If you are integrating this into a system, here is a basic wiring logic: ```python # Conceptual logic for an automated fan controller using a relay if cabinet_temperature > 45: activate_relay(GPIO_PIN_1) # Closes the 220V AC circuit to the W2AC fan status = "Cooling Active" else: deactivate_relay(GPIO_PIN_1) status = "Standby" ``` ---
