The **W2TS-N1B-R2** is a specific part number typically associated with high-performance **industrial cooling fans** or blowers, often used in telecommunications, server racks, and industrial control cabinets. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The W2TS series is designed for high airflow and reliability in demanding environments. | Feature | Specification | | :--- | :--- | | **Component Type** | AC Axial Fan / Cooling Blower | | **Input Voltage** | 200V - 230V AC | | **Frequency** | 50 / 60 Hz | | **Phase** | Single Phase | | **Bearing Type** | Dual Ball Bearing (for long life) | | **Frame Material** | Aluminum Die-cast | | **Impeller Material** | Reinforced Plastic (PBT) or Steel | --- ### 2. Electronic Characteristics The "N1B-R2" suffix usually denotes specific electrical configurations regarding speed and safety features. #### Motor Protection * **Impedance Protected:** The motor is designed to limit heat buildup even if the rotor is stalled, preventing fires or circuit damage. * **Insulation Class:** Typically Class B or F, rated for temperatures up to 130°C–155°C. #### Connection Interface * **Lead Wires:** Usually features 2 or 3 wires (Power, Neutral, and sometimes a Ground or Alarm wire). * **Capacitor:** Some models in this series require an external run capacitor to initiate the phase shift for the AC motor. --- ### 3. Performance Metrics These fans are engineered for high static pressure to push air through dense electronics. * **Airflow:** High CFM (Cubic Feet per Minute) rating, suitable for heat exchangers. * **Noise Level:** Optimized blade geometry to reduce acoustic noise while maintaining high RPM. * **Environmental Rating:** Often carries an **IP54 or IP55** rating, meaning it is protected against dust and water splashes. --- ### 4. Part Number Breakdown (Typical) While manufacturers vary slightly, the code generally follows this logic: 1. **W2T:** Series designation (AC External Rotor Motor). 2. **S:** Size or speed characteristic. 3. **N1B:** Specific electrical winding/voltage code (230V range). 4. **R2:** Revision code or specific mounting bracket configuration. --- ### 5. Application Areas * **HVAC Systems:** Used in small-scale ventilation. * **Server Cooling:** High-density rack cooling. * **Power Supplies:** Cooling large industrial UPS units. * **CNC Machines:** Cabinet cooling for motor drivers.
