The **W2AC-A14D-R2/N** is a specific model identifier typically associated with **Delta Electronics** cooling solutions, specifically within their high-performance AC axial fan series. Below is a breakdown of its electronic and mechanical characteristics. --- ### 1. Technical Specifications The following table summarizes the primary electronic and physical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Component Type** | AC Axial Fan | | **Operating Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Power Consumption** | ~14W - 16W (Variable by load) | | **Bearing Type** | Dual Ball Bearing | | **Frame Size** | 120mm x 120mm x 38mm | | **Housing Material** | Die-cast Aluminum | | **Impeller Material** | Thermoplastic (UL 94V-0 Rated) | | **Connection Type** | Lead Wires (standard) or Terminals | --- ### 2. Key Electronic Features * **Shaded Pole Motor:** This fan utilizes a shaded pole AC motor design. This is common for AC fans as it is robust, lacks brushes (reducing wear), and is self-starting. * **Impedance Protection:** The "A14D" series usually features internal impedance protection. This ensures that if the fan blades are obstructed (locked rotor), the motor will not burn out immediately due to excessive heat. * **Dual Ball Bearing System:** Unlike sleeve bearings, the dual ball bearing system allows for both vertical and horizontal mounting orientations and significantly extends the **L10 life expectancy** (often rated at 50,000+ hours at 40°C). * **Insulation Class:** Typically rated at **Class B or Class F**, meaning the internal electronic windings can withstand temperatures between 130°C and 155°C without insulation failure. --- ### 3. Part Number Suffix Breakdown While nomenclature varies slightly by manufacturer, the suffix codes generally represent: * **W2AC:** Series designation (AC Voltage, Weather/Water resistance considerations in specific sub-types). * **A14:** Often refers to the depth/power ratio or specific frame size. * **D:** Speed designation (usually High or Super High speed). * **R2/N:** Indicates specific revision levels, ROHS compliance (N for Non-toxic/Green), or specific lead-wire configurations. --- ### 4. Typical Applications These fans are engineered for industrial environments where reliability is critical: 1. **Server Racks:** Heat dissipation for networking hardware. 2. **Power Supplies:** Cooling large industrial UPS systems. 3. **Electrical Cabinets:** Preventing overheating in PLC or motor control centers. 4. **Medical Equipment:** Constant airflow for sensitive diagnostic machinery.
