The **W2TG0-4AA-R2/N** refers to a high-performance, industrial-grade **AC Axial Fan** assembly, typically manufactured by companies like **EBM-Papst**. These components are critical for thermal management in server racks, industrial cabinets, and power supplies. Below is a breakdown of its technical specifications and electronic characteristics. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | AC Axial Fan | | **Operating Voltage** | 230V AC (Standard Range: 200V - 240V) | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | ~11.0 W to 15.0 W (Depending on frequency) | | **Airflow Rate** | ~40 - 50 m³/h | | **Bearing Type** | Ball Bearing (Long-life) | | **Connection Type** | Lead Wires (2-wire) or Terminals | --- ### Core Electronic & Mechanical Components The device consists of several integrated parts designed for reliability in harsh environments: 1. **Induction Motor:** * Utilizes a **Shaded-pole motor** or a **Capacitor-run motor** design. This ensures high torque upon startup and stable RPM under load. 2. **Impedance Protection:** * The "R" in some suffixes often denotes **Impedance Protected**. This means the motor is designed so that if the rotor is locked (stalled), the internal resistance prevents the coils from overheating and catching fire without needing a thermal fuse. 3. **Ball Bearing System:** * Unlike cheaper "Sleeve" bearings, the ball bearings in this model allow for mounting in any orientation (horizontal or vertical) and offer a significantly higher MTBF (Mean Time Between Failure). 4. **Die-cast Aluminum Housing:** * Acts as a heat sink for the motor coils and provides electromagnetic shielding (EMI reduction). ### Wiring Configuration | Wire Color / Terminal | Function | Description | | :--- | :--- | :--- | | **Black / Brown** | Line (L) | Primary AC Phase Input | | **Blue** | Neutral (N) | AC Neutral Return | | **Green/Yellow** | Ground (GND) | Chassis Ground (Metal Housing) | --- ### Environmental and Safety Ratings * **Insulation Class:** Usually Class B or F, allowing for high-temperature operation (up to 70°C). * **Protection Rating:** Typically **IP20**, though specific variants may offer higher moisture protection. * **Approvals:** VDE, UL, and CSA certified for industrial use. ---
