The **W2TG0-2D1-R2/N** refers to a specific configuration of a high-performance **AC Axial Fan**, typically manufactured by brands like **EBM-Papst**. These components are widely used for thermal management in industrial equipment, server racks, and power supply units. --- ### 1. Component Specifications The following table outlines the typical technical parameters for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | AC Axial Fan | | **Voltage Range** | 230V AC (Nominal) | | **Frequency** | 50 / 60 Hz | | **Airflow** | High volume (approx. 40–50 CFM depending on housing) | | **Bearing Type** | Ball Bearing (Long life) | | **Termination** | Wire Leads (indicated by "W") | | **Housing Material** | Die-cast Aluminum / Metal | --- ### 2. Breakdown of the Model Code The alphanumeric string provides specific details about the electronic and mechanical construction: * **W**: Usually denotes a "Wall" or "Wire" configuration (Wire leads for electrical connection). * **2T**: Often refers to the motor type or pole configuration (e.g., 2-pole shaded pole motor). * **G0**: Internal design code related to the impeller geometry or motor size. * **2D1**: Indicates the voltage and phase (2 = 230V, D = Dual frequency compatible). * **R2/N**: Revision codes and specific environmental protection ratings (e.g., standard moisture protection). --- ### 3. Key Electronic Features #### A. Shaded Pole Motor The fan utilizes a shaded pole AC motor. This is a simple, robust design that does not require a starting capacitor. It is highly reliable for continuous-duty applications but has lower efficiency compared to DC brushless motors. #### B. Impedance Protection Most fans in this series are **impedance protected**. If the fan blades are physically blocked (locked rotor), the internal resistance of the motor windings prevents the current from rising to a level that would cause a fire or melt the insulation. #### C. EMI/RFI Considerations Because it operates on AC power, this fan generates very little Electromagnetic Interference (EMI) compared to PWM-controlled DC fans, making it ideal for sensitive analog equipment. --- ### 4. Typical Applications * **Server Enclosures:** For exhausting hot air from the rear of a rack. * **Industrial Control Panels:** Cooling PLCs and high-voltage power supplies. * **Medical Equipment:** High-reliability cooling for diagnostic machines. ---
