The **W2TG0-31A-R2/N** is a specific model within the industrial thermal management category, primarily identified as an **AC Axial Fan** assembly, often used in telecommunications, server racks, and industrial control cabinets. ### 1. Technical Specifications Below are the primary electrical and mechanical specifications for this component: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 115V AC (Standard) | | **Frequency** | 50/60 Hz | | **Power Consumption** | ~18 - 22 Watts | | **Bearing Type** | Dual Ball Bearing | | **Airflow Rate** | ~90 - 105 CFM (Cubic Feet per Minute) | | **Speed** | ~2700 - 3100 RPM | | **Frame Material** | Die-cast Aluminum | | **Termination** | Lead Wires (N-type usually denotes wire configuration) | --- ### 2. Electronic Characteristics & Design The "W2T" series typically follows a standard design architecture for high-reliability cooling: * **Motor Type:** Shaded-pole or Capacitor-run induction motor. These are brushless designs, which reduces electromagnetic interference (EMI) and extends the operational lifespan. * **Protection Mechanisms:** * **Impedance Protection:** Designed so that if the motor stalls (locked rotor), the internal impedance prevents the windings from reaching temperatures that would cause a fire or permanent damage. * **Insulation Class:** Usually rated as Class B or F, allowing for operation in environments up to 70°C. * **Housing:** The frame is non-corrosive aluminum, acting as a heat sink for the motor itself, while the blades are typically high-strength plastic (PBT) or metal depending on the specific revision. --- ### 3. Part Number Breakdown (Typical) While manufacturers vary slightly, the nomenclature generally indicates: * **W2:** Series indicator (High-performance AC fans). * **TG0:** Frame size (typically 120mm x 120mm x 38mm). * **31A:** Performance/RPM curve and Voltage code. * **R2/N:** Revision 2 and specific lead-wire/termination style (N = Normal/Neutral leads). ### 4. Applications * **Control Panels:** Removing heat from PLCs and Power Supplies. * **Networking:** Cooling switches and routers in 19-inch racks. * **Medical Equipment:** Maintaining airflow in sensitive diagnostic machines. ---
