The **W2CE-511-R2** is a specialized electronic component primarily categorized as an **AC Power Entry Module**. It combines multiple power-related functions into a single integrated housing, typically used in medical, industrial, and high-performance computing equipment. --- ### 1. Key Technical Specifications The "W2CE" series by manufacturers like Delta Electronics or Schurter (depending on the specific sourcing line) generally adheres to the following parameters: | Parameter | Specification | | :--- | :--- | | **Component Type** | IEC 60320-1 Inlet (C14 Type) | | **Voltage Rating** | 115V / 250V AC | | **Current Rating** | 1A to 10A (Model specific, usually 5A for "511") | | **Operating Frequency** | 50/60 Hz | | **Mounting Type** | Snap-in or Screw Mount | | **Termination** | Quick Connect / Solder Terminals | --- ### 2. Integrated Components The "511-R2" designation indicates a specific configuration of internal electronic parts. A standard unit includes: #### A. EMI/RFI Filter The core of the W2CE-511-R2 is a **low-pass filter circuit**. It prevents electromagnetic interference (EMI) from the power line from entering the device and stops high-frequency noise generated by the device's internal switching power supply from leaking back into the mains. * **Components:** Inductors (Common mode chokes), X-capacitors (Line-to-Line), and Y-capacitors (Line-to-Ground). #### B. Fuse Holder The unit contains a compartment for one or two fuses (usually 5x20mm). This provides overcurrent protection for the downstream electronics. #### C. Power Switch The "R2" suffix often denotes a **DPST (Double Pole Single Throw)** rocker switch. This allows the user to physically disconnect both the Live and Neutral lines for safety. --- ### 3. Application Use Cases Due to its integrated nature, the W2CE-511-R2 is found in: 1. **Medical Equipment:** High-performance filtering to meet leakage current requirements. 2. **Instrumentation:** Precision measurement tools requiring clean power. 3. **Server Chassis:** Standardized power inlets for rack-mounted hardware. --- ### 4. Circuit Diagram Representation The internal schematic typically follows this logic: ```text [AC Inlet] -> [Fuse] -> [Rocker Switch] -> [EMI Filter] -> [Output Terminals] ``` ---
