The **W2AC-A14D-R2** is a specific model of an AC axial fan, typically manufactured by cooling solution specialists (often associated with brands like NMB-MAT or similar industrial fan providers). It is designed for thermal management in industrial equipment, power supplies, and server racks. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The following table summarizes the key electrical and physical attributes of the W2AC-A14D-R2: | Feature | Specification | | :--- | :--- | | **Input Voltage** | 230V AC (Standard) | | **Frequency** | 50 / 60 Hz | | **Input Power** | ~14W - 16W (varies by frequency) | | **Current Rating** | ~0.10A - 0.12A | | **Speed** | 2,700 - 3,100 RPM | | **Airflow** | ~90 - 110 CFM | | **Bearing Type** | Dual Ball Bearing | | **Frame Size** | 120mm x 120mm x 38mm | | **Termination** | Lead Wires or Terminal Pins | --- ### 2. Electronic Components & Features The W2AC-A14D-R2 consists of several critical electronic sub-assemblies that ensure reliable operation: #### A. Shaded Pole Motor / Capacitor Run Motor * **Design:** Most AC fans of this size utilize a shaded-pole or permanent split capacitor motor. This design is highly reliable as it lacks brushes that wear out over time. * **Winding:** Copper windings with high-temperature insulation (Class B or Class F) to prevent short-circuiting under continuous heavy loads. #### B. Impedance Protection * The "R2" designation often implies internal safety mechanisms. * **Impedance Protected:** The motor is designed so that if the fan blades are obstructed (locked rotor), the impedance of the windings limits the current flow to prevent the coils from overheating and catching fire. #### C. Bearing System * **Dual Ball Bearings:** Unlike cheaper sleeve bearings, ball bearings allow for operation at higher temperatures and provide a longer MTBF (Mean Time Between Failures), typically rated for 50,000+ hours. #### D. Housing and Material * **Frame:** Usually Die-cast Aluminum, which acts as a heat sink for the motor. * **Impeller:** Reinforced plastic (PBT) or Metal, designed for aerodynamic efficiency and low noise (approx. 40-45 dB). --- ### 3. Wiring Configuration Depending on the specific revision, the wiring follows standard AC protocols: 1. **Live (L):** Brown or Black wire. 2. **Neutral (N):** Blue or White wire. 3. **Ground (G):** Green/Yellow (if a metal frame grounding point is provided). --- ### 4. Applications * **Control Cabinets:** Cooling of PLCs and industrial drives. * **Medical Equipment:** Heat dissipation for high-power imaging or laboratory tools. * **Server Racks:** Standard 120mm footprint makes it compatible with most rack-mount enclosures.
