The **W2TG0-331-R2/UL** is a specialized high-performance AC axial fan produced by **Wagan/Nidec (Nidec Servo)**. It is primarily used in industrial cooling applications where reliability and high airflow are required. --- ### 1. Technical Specifications The following table outlines the core electronic and mechanical parameters for this specific model: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (Single Phase) | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | ~30W to 40W (Dependent on frequency) | | **Speed (RPM)** | Approx. 2700 - 3250 RPM | | **Airflow** | High Volume (Specific to 200mm class) | | **Bearing Type** | Dual Ball Bearing | | **Termination** | Lead Wires (UL Recognized) | | **Frame Size** | 200mm x 200mm x 60mm | --- ### 2. Key Electronic Components & Design The "Electronic" profile of this part is centered around its motor construction and safety compliance: #### A. Shaded Pole or Capacitor-Run Motor * **Induction Motor:** Unlike DC fans that use a PCB with a controller, this AC fan typically utilizes a permanent split capacitor or shaded pole induction motor. * **Reliability:** Because it lacks complex integrated circuits (ICs), it is highly resistant to Electromagnetic Interference (EMI) and power surges compared to low-voltage DC fans. #### B. The "UL" Suffix (Safety Certification) * The **UL** designation indicates that the internal wiring, insulation system, and motor protection meet **Underwriters Laboratories** safety standards. * **Thermal Protection:** The motor usually includes an impedance protection or a thermal cutoff to prevent fires if the rotor is locked (stalled). #### C. Environmental Sealing * The internal windings are typically vacuum-impregnated with varnish to protect against moisture and vibration, which is critical for industrial "R2" series variants. --- ### 3. Wiring Diagram Logic To integrate this part into a system, the wiring logic is generally as follows: ```yaml Wiring_Colors: Black/Brown: Line (Live) White/Blue: Neutral Green/Yellow: Ground (Safety Earth) ``` *Note: Always verify the specific wire colors on the physical label, as lead-wire configurations can vary by production batch.* --- ### 4. Typical Applications Due to its 230V rating and heavy-duty build, it is commonly found in: * **Server Racks:** Large-scale telecommunication enclosures. * **Industrial Control Panels:** Cooling high-voltage power supplies and PLCs. * **HVAC Systems:** Used as an exhaust or circulation fan in cleanrooms.
