The **W2TG0-2CB-R** belongs to a series of high-performance components, typically identified as an **AC axial fan** or a cooling solution component produced by manufacturers like ebm-papst. Below is a detailed breakdown of the electronic and mechanical specifications for this part. --- ### 1. Technical Specifications The following table outlines the primary electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | AC Axial Compact Fan | | **Nominal Voltage** | 230 VAC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | ~11 W to 13 W | | **Speed (RPM)** | 2700 - 3200 RPM | | **Airflow Capacity** | ~40 - 50 m³/h | | **Bearing Type** | Ball Bearing | | **Termination** | 2 Flat Terminals (2.8 x 0.5 mm) | --- ### 2. Key Electronic Features * **Shaded-Pole Motor:** The internal motor is typically a 2-pole shaded-pole motor. This design is highly reliable for AC applications because it lacks brushes, reducing mechanical wear and electrical noise. * **Impedance Protection:** The motor is "protected against locking." This means the windings are designed so that if the fan blade is physically obstructed (stalled), the impedance of the coils prevents the current from rising to a level that would cause a fire or melt the insulation. * **Capacitor-less Design:** Unlike larger industrial motors, these compact units generally do not require an external starting capacitor, simplifying the wiring to a direct AC connection. --- ### 3. Material and Environmental Construction * **Housing:** Die-cast aluminum. This acts as a heat sink for the internal motor coils, extending the component's lifespan. * **Impeller:** Fiberglass-reinforced plastic (PA plastic). This reduces the rotational mass, allowing for faster spin-up times and lower power draw. * **Ingress Protection:** Usually rated at **IP20**, meaning it is protected against solid objects but not moisture; however, specific variants may have higher environmental coatings. --- ### 4. Common Applications Due to its compact size (typically 80mm x 80mm x 25mm or 38mm), it is used in: 1. **Server Racks:** For localized spot cooling of CPUs or Power Supply Units (PSUs). 2. **Control Cabinets:** To prevent heat buildup in industrial PLC enclosures. 3. **Medical Equipment:** Cooling for diagnostic devices where high reliability is required. ---
