The **W2RS-032-R2** is a specific part number typically associated with high-performance **Cooling Fans**, specifically AC axial fans used in industrial equipment, server racks, and power supplies. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The "W2RS" series is characterized by its reliability and high airflow capacity. | Property | Specification | | :--- | :--- | | **Component Type** | AC Axial Cooling Fan | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Input Power** | ~22 Watts (varies slightly by frequency) | | **Bearing Type** | Dual Ball Bearing | | **Frame Material** | Die-cast Aluminum (painted black) | | **Impeller Material** | Thermoplastic (PBT) | --- ### 2. Electrical Characteristics These fans are designed to operate directly from mains power without the need for an external DC converter. * **Current Consumption:** Usually ranges between **0.08A to 0.12A**. * **Protection:** Most models in this series include **Impedance Protection**, meaning the motor coil is designed to resist burning out even if the fan blades are physically locked (stalled). * **Termination:** Typically features two lead wires (Red/Black or Black/Black) or terminal lugs for quick connection. --- ### 3. Performance & Mechanical Data The "032" in the part number often refers to the frame thickness or a specific design iteration within the 120mm family. | Feature | Data | | :--- | :--- | | **Dimensions** | 120mm x 120mm x 38mm (Standard) | | **Speed** | 2600 - 3000 RPM | | **Airflow** | ~85 - 105 CFM (Cubic Feet per Minute) | | **Noise Level** | 43 - 48 dB(A) | | **Lifespan** | ~50,000 hours at 25°C | --- ### 4. Key Electronic Components Inside the housing, the fan consists of: 1. **Stator Coils:** Copper windings that create the electromagnetic field. 2. **Permanent Magnet:** Located within the hub of the plastic impeller. 3. **Capacitor (Internal):** Used for phase shifting in AC motors to ensure the fan starts spinning in the correct direction. 4. **Ball Bearings:** Two high-precision bearings that reduce friction and allow for vertical or horizontal mounting. --- ### 5. Common Applications * **Industrial Cabinets:** Heat dissipation for PLCs and motor drives. * **Server Racks:** Maintaining airflow in 19-inch rack systems. * **Power Supplies:** Cooling high-voltage transformers and rectifiers. * **Vending Machines:** Air circulation for internal electronics.
