The **W2AC-A1AC-R2/N** is a specific part number typically associated with high-performance cooling solutions, most commonly identified as an AC Axial Fan from the **W2 series**. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Input Voltage** | 115V AC (Nominal) | | **Frequency** | 50 / 60 Hz | | **Current Consumption** | Approx. 0.20 A to 0.25 A | | **Power Rating** | ~18 Watts to 24 Watts | | **Speed** | 2,800 - 3,250 RPM | | **Airflow** | ~90 - 110 CFM (Cubic Feet per Minute) | | **Bearing Type** | Dual Ball Bearing (Standard for R2/N series) | --- ### 2. Component Composition This part is comprised of several critical electronic and mechanical sub-assemblies: #### A. The Induction Motor The heart of the unit is a **Shaded Pole** or **Permanent Split Capacitor (PSC)** AC induction motor. It is designed for continuous operation and utilizes copper windings with high-grade insulation (usually Class B or F) to withstand heat. #### B. Thermal Protection The "/N" designation often implies internal protection features. These units typically include: * **Impedance Protection:** The motor is designed so that if the rotor is stalled, the internal resistance prevents the windings from reaching temperatures that would cause a fire. * **Thermal Cut-off:** Some variants include a thermal fuse that breaks the circuit if the internal temperature exceeds safety limits. #### C. Housing and Material * **Frame:** Die-cast aluminum alloy, which acts as a heat sink for the motor. * **Impeller:** Reinforced PBT plastic or metal (depending on the specific revision), balanced to reduce EMI and vibration. --- ### 3. Wiring and Connection The **R2/N** suffix generally indicates the termination style: * **Lead Wires:** Usually comes with two or three UL-recognized lead wires (Line, Neutral, and sometimes Ground). * **Length:** Standard leads are typically 300mm (12 inches). --- ### 4. Application Use Cases Due to its robust electronic design, this part is frequently used in: 1. **Server Racks:** To exhaust heat from high-density computing units. 2. **Industrial Control Panels:** To maintain ambient temperatures for PLCs and Inverters. 3. **Power Supplies:** Large-scale rectifiers and UPS systems. ---
