The **W2TG0-2D1-R/N** is a specific model identifier typically associated with **industrial AC cooling fans**, often manufactured by companies like **EBM-PAPST** or similar high-end thermal management firms. These fans are designed for heavy-duty applications like server racks, control cabinets, and medical equipment. --- ### 1. Technical Specifications Overview Below is a breakdown of the typical electronic and mechanical characteristics for this series: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (Nominal) | | **Frequency** | 50 / 60 Hz | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Power Consumption** | Approx. 20W - 30W (Depending on load) | | **Airflow Capacity** | ~90 - 110 CFM | | **Speed (RPM)** | 2700 - 3000 RPM | | **Housing Material** | Die-cast aluminum | | **Connection Type** | Lead wires (R/N usually denotes Red/Neutral or specific wiring) | --- ### 2. Key Electronic Components #### A. Shaded-Pole Motor The internal motor is usually a **shaded-pole AC motor**. - **Simple Design:** It uses a copper ring (shading coil) around part of each pole to create a rotating magnetic field. - **Reliability:** It contains no brushes or complex electronic switching, making it highly resistant to electromagnetic interference (EMI). #### B. Thermal Protection Most fans in this series include an **Impedance Protection** or a **Thermal Cutoff**. - **Impedance Protected:** The motor is designed so that if the rotor is locked (stalled), the heat generated by the windings will not exceed the insulation's temperature limit, preventing a fire without needing a separate fuse. #### C. Dual Ball Bearing System From an electromechanical standpoint, the use of ball bearings over sleeve bearings ensures: - Lower friction at high temperatures. - Horizontal or vertical mounting versatility. - MTBF (Mean Time Between Failure) often exceeding 50,000 hours. --- ### 3. Wiring Configuration The suffix **/N** often refers to the termination type or a specific electrical variant. ```markdown L (Line) -----> [ Black/Brown Wire ] N (Neutral) -----> [ Blue/White Wire ] PE (Earth) -----> [ Green/Yellow Wire ] ``` --- ### 4. Typical Applications * **Enclosure Cooling:** Preventing heat buildup in PLC and electrical cabinets. * **Networking Gear:** Cooling high-density server switches. * **Industrial Power Supplies:** Active heat dissipation for large transformers or rectifiers.
