The **W2PP-92YN-R2/N** refers to a high-performance **Industrial AC Axial Fan** assembly, typically manufactured by companies like **Welling** or specialized cooling component vendors. These fans are designed for heavy-duty thermal management in server racks, power supplies, and industrial control cabinets. --- ### 1. Technical Specifications Below are the primary electrical and mechanical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50/60 Hz | | **Power Consumption** | Approximately 18W - 25W (Varies by load) | | **Bearing Type** | Dual Ball Bearing (indicated by "2B" or "R2" logic) | | **Termination** | 2-Wire or 3-Wire (Lead wires or terminals) | | **Housing Material** | Die-cast Aluminum (painted black) | | **Blade Material** | Reinforced Thermoplastic (PBT) | --- ### 2. Key Electronic Components The internal electronics of the W2PP-92YN-R2/N focus on converting AC power into rotational torque efficiently: 1. **Shaded-Pole or PSC Motor:** It uses an AC induction motor. These are brushless, meaning they have high reliability and a long lifespan because there are no carbon brushes to wear out. 2. **Dual Ball Bearing System:** The "R2" designation often implies a specific bearing configuration designed for high-speed stability and heat resistance, allowing the fan to operate in temperatures up to 70°C. 3. **Impedance Protection:** The motor windings are "impedance protected." This means if the fan blades are obstructed (locked rotor), the internal resistance of the coils prevents the motor from drawing enough current to catch fire. 4. **EMI Suppression:** Often includes basic filtering components to prevent the AC motor from introducing electrical noise back into the power line. --- ### 3. Physical Dimensions This model typically follows standard industrial sizing for ease of replacement: * **Frame Size:** 92mm x 92mm * **Thickness:** 25mm or 38mm (depending on the specific "YN" sub-variant) * **Mounting:** 4-hole corner pattern for standard M4 screws. --- ### 4. Typical Applications * **UPS Systems:** Cooling the power inverters. * **Networking Gear:** Cooling high-density switches and routers. * **CNC Machines:** Providing airflow to the control logic board. * **Welding Equipment:** Dissipating heat from high-current transformers.
