The **W2AC-A13B-R2** is a specialized power entry module, typically manufactured by **Schurter** or similar high-end electronic component providers. This component is designed to integrate power input, filtering, and switching into a single compact housing. ### 1. Component Overview This part is a **Power Entry Module (PEM)** designed for industrial and medical applications where space-saving and electrical noise suppression are critical. | Feature | Specification | | :--- | :--- | | **Component Type** | C14 Power Entry Module | | **Mounting Type** | Snap-in or Screw-on (depending on specific R-variant) | | **Current Rating** | 1A - 10A (Model specific) | | **Voltage Rating** | 250 VAC | | **Integrated Parts** | IEC Connector, Fuse Holder, Power Switch | --- ### 2. Key Electronic Sections #### A. IEC 60320-1 C14 Inlet This is the standard male connector that accepts a standard C13 power cord (commonly used for PCs and lab equipment). It is rated for high-temperature operations and ensures a secure physical connection. #### B. Integrated Fuse Holder The module includes a drawer for **5x20mm fuses**. * **Safety:** Protects the downstream electronics from overcurrent. * **Configuration:** Usually supports a 2-pole (double fuse) configuration for enhanced safety in medical or sensitive environments. #### C. 2-Pole Rocker Switch The "A13B" designation often refers to the specific switch configuration. * **Function:** DPST (Double Pole Single Throw). * **Benefit:** It disconnects both the Line (Live) and Neutral wires simultaneously, ensuring the device is completely isolated from the AC source when turned off. #### D. EMC/EMI Filtering (If applicable) Many modules in this series include an internal RFI (Radio Frequency Interference) filter. * **Capacitors:** X2 capacitors for line-to-line noise. * **Inductors:** Common-mode chokes to suppress high-frequency interference. --- ### 3. Pinout and Internal Wiring The back of the module typically features **6.3 x 0.8 mm quick-connect terminals**. ```text Internal Logic: [AC Inlet] --> [Fuse Holder] --> [Rocker Switch] --> [Output Terminals] | [EMI Filter] (Optional) ``` ### 4. Application Areas * **Medical Equipment:** Due to high safety standards and leakage current requirements. * **Lab Instrumentation:** Where clean power and easy fuse access are necessary. * **Industrial Automation:** Provides a professional, filtered interface for control panels. ---
