The **W2TG0-3AB-R** is a specific part number typically associated with **AC Axial Fans**, often manufactured by companies like **Nidec (Japan Servo)** or used in specialized industrial equipment. These components are designed for high-performance cooling in environments requiring reliable airflow. --- ### 1. General Specifications While specific data can vary slightly by manufacturer version, the "W2T" series generally follows these technical parameters: | Parameter | Typical Value | | :--- | :--- | | **Component Type** | AC Axial Cooling Fan | | **Input Voltage** | 200V - 230V AC (50/60Hz) | | **Bearing Type** | Dual Ball Bearing (for longevity) | | **Frame Material** | Aluminum Die-cast | | **Impeller Material** | Plastic (PBT) or Steel (depending on sub-series) | | **Connection Type** | Lead Wires or Terminals | --- ### 2. Breakdown of the Part Number Though naming conventions differ slightly by brand, the code usually breaks down as follows: 1. **W2T**: Refers to the series (Square AC Axial Fan). 2. **G0**: Often denotes the frame size (Standard 120mm x 120mm x 38mm is common for this series). 3. **3AB**: Indicates electrical characteristics (Voltage rating of 230V) and speed rating. 4. **R**: Typically stands for "RoHS Compliant" or a specific rotation direction/protection type. --- ### 3. Key Electronic Features * **Induction Motor:** Uses a shaded-pole or capacitor-run induction motor to drive the blades using AC power. * **Impedance Protection:** Most fans in this series are "Impedance Protected," meaning the motor is designed to withstand a locked rotor condition without catching fire. * **Dual Ball Bearings:** Engineered for horizontal or vertical mounting with a lifespan often exceeding 50,000 hours at 40°C. * **Thermal Cutoff:** High-end variants include an internal thermal fuse to disconnect power if the internal temperature exceeds safe limits. --- ### 4. Applications This part is commonly found in: * **Server Racks:** To exhaust heat from high-density computing hardware. * **Industrial Control Panels:** To prevent overheating of PLCs and Inverters. * **Medical Equipment:** Large diagnostic machines requiring constant airflow. * **Power Supplies:** Cooling high-wattage AC-DC converters. ---
