The **W2TS-2B2-R2/N** refers to a high-performance **Industrial AC Cooling Fan** (specifically part of the W2TS series). These components are critical for thermal management in server racks, power supplies, and industrial control cabinets. Below is a breakdown of the electronic and mechanical specifications for this component. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | Approx. 36W - 40W | | **Speed (RPM)** | 2,700 - 3,000 RPM | | **Airflow Capacity** | Approx. 190 - 210 m³/h | | **Bearing Type** | Dual Ball Bearing (High Reliability) | | **Termination** | Lead Wires or Terminal Pins (Model dependent) | --- ### 2. Key Electronic Components & Design #### A. The Motor Structure The unit utilizes an **External Rotor Induction Motor**. Unlike standard motors where the rotor is inside the stator, the external rotor design allows the fan blades to be integrated directly onto the rotor. This leads to: * Compact axial depth. * Better heat dissipation for the motor coils. #### B. Insulation and Protection * **Class B Insulation:** The internal windings are rated to withstand temperatures up to 130°C. * **Impedance Protection:** The motor is electronically designed to limit current flow if the rotor is stalled (locked), preventing the coils from burning out. #### C. Construction Materials * **Frame:** Die-cast aluminum alloy with a black anti-corrosion coating. This acts as a heat sink for the electronics. * **Impeller:** Reinforced plastic (PBT) or metal, designed for aerodynamic efficiency and low noise. --- ### 3. Application Areas Because of its high voltage rating and robust airflow, this part is typically found in: 1. **Telecommunications:** Cooling for base stations and switching equipment. 2. **Power Electronics:** Cooling for large Inverters and UPS systems. 3. **Industrial Automation:** Ventilation for CNC machines and PLC cabinets. --- ### 4. Part Number Breakdown (W2TS Series) * **W2TS:** Series designation for AC Axial Fans. * **2B2:** Typically indicates the frame size (120mm x 120mm x 38mm) and voltage class (200-240V). * **R2/N:** Revision code indicating specific bearing types or environmental protection ratings (e.g., moisture resistance).
