The **W2AC-AZAA-R2** is a specialized electronic component, typically identified as a **high-performance AC-DC fan or blower assembly**, often utilized in industrial cooling and server environments. Specifically, this part number is associated with products from manufacturers like **Delta Electronics** or **Nidec**. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | AC Axial Fan / Centrifugal Blower | | **Input Voltage** | 100V - 120V AC (Standard US/Japan utility power) | | **Frequency** | 50/60 Hz | | **Current Rating** | Typically 0.10A to 0.25A (varies by specific load) | | **Bearing Type** | Dual Ball Bearing (for long MTBF) | | **Termination** | Lead wires or Terminal lugs (R2 revision specific) | --- ### 2. Key Electronic Components The "Electronic Parts" within the W2AC-AZAA-R2 assembly consist of the following internal subsystems: * **Induction Motor:** Most AC fans in this series use a shaded-pole or permanent split capacitor motor. This allows the fan to operate directly from the AC mains without a complex DC conversion circuit. * **Thermal Protection:** Includes an internal impedance protection or a thermal cutoff. This prevents the windings from catching fire if the rotor is locked (stalled). * **Stator Windings:** High-quality copper windings insulated to Class B or Class F standards to withstand operational heat. * **EMI Suppression:** Often contains basic capacitive filtering to ensure the motor does not inject electrical noise back into the power line. --- ### 3. Part Number Decoder (Typical) While manufacturers vary slightly, the "AZAA-R2" suffix usually breaks down as follows: 1. **W2AC:** Series designation (Window/Wall AC cooling). 2. **AZ:** Airflow and Static Pressure rating (High performance). 3. **AA:** Mechanical interface (Standard mounting flange). 4. **R2:** Revision 2 (Indicates an update in electronic efficiency or a change in the lead wire connector). --- ### 4. Applications * **Server Racks:** Exhausting heat from high-density computing units. * **Power Supplies:** Cooling large industrial transformers or UPS systems. * **Cabinet Ventilation:** Used in electrical enclosures to prevent overheating of PLCs and Motor Drives.
