The **W2TS-11B-R2** is a specific part number typically associated with high-performance **Industrial AC Axial Fans**, often manufactured by brands like **Wizmart** or distributed for use in server racks, industrial control cabinets, and cooling systems. --- ### 1. Technical Specifications The "W2TS" series generally represents a 120mm x 120mm x 38mm form factor, which is the industry standard for high-airflow cooling. | Parameter | Specification (Typical) | | :--- | :--- | | **Input Voltage** | 110V / 120V AC (50/60Hz) | | **Current / Power** | ~0.14A - 0.25A / 18W - 22W | | **Bearing Type** | Dual Ball Bearing (indicated by 'B') | | **Frame Material** | Die-cast Aluminum (Painted Black) | | **Impeller Material** | Thermoplastic PBT (UL 94V-0) | | **Termination** | Lead Wires (indicated by '11B') | | **Speed** | 2,600 - 3,000 RPM | | **Airflow** | 80 - 105 CFM | --- ### 2. Breakdown of the Model Number While nomenclature varies slightly by manufacturer, here is the standard electronic breakdown for this series: * **W2TS**: Series designation (likely 120mm AC high-speed fan). * **11**: Voltage code (1 = 110/120V AC). * **B**: **Ball Bearing**. This is critical for industrial use as ball bearings offer a longer lifespan (approx. 50,000+ hours) and allow the fan to be mounted in any orientation. * **R2**: Revision or specific impedance protection rating. --- ### 3. Key Features 1. **Impedance Protection:** The motor is designed to resist burnout even if the blades are physically restricted (locked rotor protection). 2. **Dielectric Strength:** Usually rated for 1500V AC for 1 minute between the frame and terminals, ensuring safety in high-voltage cabinets. 3. **Environmental Resistance:** The aluminum frame acts as a heat sink for the motor, allowing it to operate in ambient temperatures up to 70°C. --- ### 4. Wiring Diagram (Standard AC) Since this is an AC fan, it does not require a DC power supply or polarity management. ```text [ AC Power L ] -------- (Black Wire) ---- [ Motor ] [ AC Power N ] -------- (Black Wire) ---- [ Motor ] [ Ground ] -------- (Green/Yellow) -- [ Frame ] (If applicable) ``` ---
