The **W2AC-AZCB-R2/N** is a specific model identifier for an industrial-grade **AC Axial Fan**, typically manufactured by brands like **Wentech** or affiliated industrial cooling providers. These fans are designed for high-performance thermal management in server racks, control cabinets, and industrial machinery. --- ### 1. Technical Specifications The following table outlines the core electronic and mechanical parameters of the W2AC-AZCB-R2/N: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Bearing Type** | Dual Ball Bearing (High Reliability) | | **Power Consumption** | Approx. 20W - 30W (varies by load) | | **Housing Material** | Die-cast Aluminum (provides EMI shielding) | | **Impeller Material** | PBT Thermoplastic (UL94V-0 Rated) | | **Speed** | ~2600 to 3000 RPM | | **Termination** | Lead Wires (standard for R2/N series) | --- ### 2. Key Electronic Components & Features #### A. Motor Architecture The unit utilizes an **Asynchronous External Rotor Motor**. * **Capacitor-Run:** Most models in this series use an integrated capacitor to initiate and maintain phase shift for rotation. * **Impedance Protection:** The motor is electronically protected against burnout. If the fan blades are blocked (locked rotor), the impedance of the windings limits the current to prevent overheating and fire hazards. #### B. The Bearing System (Dual Ball) The "AZCB" designation often refers to the high-end **Ball Bearing** construction. * **Longevity:** Rated for approximately 50,000 to 70,000 hours of continuous operation. * **Mounting:** Unlike sleeve bearings, ball bearings allow the fan to be mounted in any orientation (horizontal, vertical, or angled) without affecting lifespan. #### C. EMI and Safety Features * **Die-cast Frame:** The aluminum frame acts as a heat sink for the motor windings and provides structural rigidity. * **Insulation Class:** Typically Class B or Class F, allowing the electronic components to withstand internal temperatures up to 130°C–155°C. * **N-Suffix (R2/N):** Often denotes environmental compliance (RoHS) or specific termination types (Natural/Standard wiring). --- ### 3. Wiring Diagram (Standard AC) Since this is an AC-powered component, the wiring is straightforward: ```yaml Wiring Configuration: - Wire 1 (Black/Brown): Live (L) 220-240VAC - Wire 2 (Black/Blue): Neutral (N) - Ground (Green/Yellow): Chassis Ground (if applicable) ``` --- ### 4. Applications * **Telecom Racks:** Cooling for switches and routers. * **Industrial Power Supplies:** Dissipating heat from large transformers. * **HVAC Equipment:** Used as an exhaust or intake fan for localized cooling zones.
