The **W2AC-ACCA-R/N** is a specific part number typically associated with **Delta Electronics' W-Series** of professional power supplies or power distribution units. It is specifically a **Power Cord / Power Entry Module** component. Below is the detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications This part is designed for high-reliability industrial and server environments. It functions as the interface between the AC power source and the internal power system. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Delta Electronics | | **Component Type** | AC Power Cord / Inlet Assembly | | **Voltage Rating** | 125V - 250V AC | | **Current Rating** | 10A - 15A (Typical) | | **Connector Type** | C13 / C14 (IEC Standard) | | **RoHS Status** | Compliant | --- ### 2. Key Electronic Components The assembly usually consists of three primary electronic segments: #### A. The Physical Connector (IEC 320) * **Plug Type:** Generally an IEC C14 inlet or a molded C13 connector. * **Contact Material:** High-conductivity copper alloy with nickel or tin plating to prevent oxidation and ensure low contact resistance. #### B. Internal Wiring (The "W2AC" Series) * **Gauge:** Typically 14 AWG or 18 AWG depending on the specific current draw requirements. * **Insulation:** PVC or LSZH (Low Smoke Zero Halogen) rated for 105°C, ensuring safety during continuous high-load operations. #### C. Termination & Shielding * **Grounding:** Includes a dedicated grounding wire (Green/Yellow) to ensure chassis safety and ESD protection. * **Strain Relief:** The "R/N" designation often refers to a specific **Right-angle** or **Straight** over-mold configuration to prevent mechanical failure at the connection point. --- ### 3. Part Number Decoding (Nomenclature) While exact vendor codes can vary, the nomenclature generally breaks down as follows: | Code | Meaning | | :--- | :--- | | **W2** | Series designation (W-Series high-durability) | | **AC** | Power type (Alternating Current) | | **ACCA** | Cable/Connector configuration code | | **R/N** | Connector Orientation (R = Right Angle, N = Neutral/Straight) | --- ### 4. Application Areas This part is commonly found in the following electronic systems: * **Server Racks:** Providing the bridge between the PDU (Power Distribution Unit) and the Server PSU. * **Medical Equipment:** Due to high insulation standards. * **Industrial Automation:** Used in control panels where vibration resistance is required.
