The part number **W2AC-AAAA-R/N** typically refers to a high-performance **Industrial AC Axial Fan** or a specific **Power Supply Component**, often associated with brands like **Delta Electronics** or **Wurth**. In the context of cooling solutions, it belongs to a series designed for heavy-duty thermal management. --- ### 1. Technical Specifications (General) | Feature | Specification | | :--- | :--- | | **Component Type** | AC Axial Fan / Cooling Module | | **Input Voltage** | 100V - 240V AC (Frequency: 50/60 Hz) | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Termination** | Lead Wires (L) or Terminal (T) | | **Frame Material** | Die-cast Aluminum / Thermoplastic PBT | | **Protection** | Impedance Protected / Thermal Protection | --- ### 2. Breakdown of the Part Number While nomenclature varies slightly by manufacturer, the code generally breaks down as follows: * **W2AC**: The Series identifier (High-performance AC line). * **AAAA**: Specific frame size and motor configuration (e.g., 120mm x 120mm x 38mm). * **R**: Often indicates **Rotation** direction (Clockwise/Counter-clockwise) or **RoHS** compliance. * **N**: Represents the version or **Noise level** rating (usually "Normal" or "Standard Speed"). --- ### 3. Key Electronic Characteristics 1. **Induction Motor:** These parts usually utilize a shaded-pole or capacitor-run induction motor, ensuring high reliability under continuous operation. 2. **EMI Suppression:** Often includes internal filtering to prevent electromagnetic interference with surrounding sensitive electronics. 3. **Dielectric Strength:** Built to withstand high voltage spikes, typically tested up to 1500VAC for 1 minute. 4. **Environmental Sealing:** Usually rated **IP54 or IP55**, meaning the internal electronics are protected against dust and moisture splashes. --- ### 4. Common Applications * **Server Racks:** Removing heat from high-density computing hardware. * **Industrial Control Panels:** Cooling PLCs and power inverters. * **Medical Equipment:** High-reliability cooling for imaging or diagnostic tools. * **Power Supplies:** Integrated into large-scale AC/DC power converters.
