The **W2TG0-231-R** is a specific part number typically associated with high-performance AC axial fans, often manufactured by companies like **Delta Electronics** or under specific industrial server/telecom specifications. --- ### 1. Component Overview The W2TG0-231-R is an **AC Axial Fan** designed for cooling electronic enclosures, server racks, and industrial machinery. It is characterized by its reliability and high airflow-to-size ratio. ### 2. Technical Specifications Below is a summary of the typical electronic and mechanical characteristics for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Input Voltage** | 230V AC | | **Frequency** | 50 / 60 Hz | | **Current Rating** | ~0.10A to 0.14A | | **Power Consumption** | ~18W - 22W | | **Speed** | 2600 - 3000 RPM | | **Bearing Type** | Dual Ball Bearing | | **Frame Material** | Die-cast Aluminum | | **Termination** | Terminals or Lead Wires | --- ### 3. Key Electronic Features * **Motor Type:** Shaded pole motor or Capacitor-run induction motor (brushless AC design). This eliminates the need for brushes, reducing electromagnetic interference (EMI) and increasing lifespan. * **Insulation Class:** Usually Class B or F, meaning the internal wiring is rated to handle high temperatures (up to 130°C - 155°C) without the insulation breaking down. * **Protection Mechanisms:** * **Impedance Protection:** The motor is designed so that if the fan blade is stalled (locked rotor), the internal resistance prevents the coils from overheating and catching fire. * **Dielectric Strength:** High voltage tolerance between the frame and the electrical terminals (typically 1500V AC for 1 minute). ### 4. Physical Construction * **Housing:** Robust aluminum alloy frame which acts as a heat sink for the motor coils. * **Impeller:** Typically made of glass-fiber reinforced plastic (PBT) or metal, UL 94V-0 flame retardant rated. * **Mounting:** Standard 120mm x 120mm x 38mm form factor (common in networking cabinets). --- ### 5. Application Areas 1. **Server Racks:** Extracting hot air from high-density computing environments. 2. **Power Supplies:** Cooling high-wattage AC/DC converters. 3. **Control Cabinets:** Preventing thermal buildup in PLC and industrial automation panels.
