### Overview: JFK-6A-R Power Entry Module The **JFK-6A-R** is a specific model of a **Power Entry Module (PEM)** manufactured by **Inalways Corporation**. It integrates several electrical components into a single housing to simplify the connection between a power cord and electronic equipment. --- ### 1. Key Electronic Components The "6A" in the part number signifies its current rating, while the "R" typically denotes compliance or specific mounting configurations. Below are the core electronic parts integrated into this module: | Component | Function | | :--- | :--- | | **IEC 60320 C14 Inlet** | The male connector interface that accepts a standard C13 power cord (common in PCs and monitors). | | **Fuse Holder** | A compartment for a **5x20mm glass or ceramic fuse** to protect the device from overcurrent. | | **Rocker Switch** | A physical DPST (Double Pole Single Throw) or SPST switch to turn the power ON/OFF. | | **EMI/RFI Filter** | (Internal) A circuit consisting of inductors and capacitors to suppress electromagnetic interference. | --- ### 2. Technical Specifications The electronic performance of the JFK-6A-R is defined by the following parameters: * **Rated Voltage:** 115V / 250V AC * **Rated Current:** 6 Amperes (at 250V AC) * **Operating Frequency:** 50/60 Hz * **Leakage Current:** Typically less than 0.5mA at 250V AC (Standard for medical or IT equipment). * **Dielectric Strength:** 2000V AC for 1 minute between Line and Ground. --- ### 3. Circuit Wiring & Terminals The back of the module features metal terminals for connecting to the internal electronics of the device. ```text L (Line) ---- [ Fuse ] ---- [ Switch ] ---- Output L N (Neutral) ---- [ Filter ] -- [ Switch ] ---- Output N E (Earth) ---------------------------------- Output E ``` * **Terminals:** Usually **Quick-connect (Faston)** 4.8mm or 6.3mm tabs, or Solder terminals. * **Mounting:** Snap-in or Screw-mount (depending on the specific "R" sub-variant). --- ### 4. Safety and Compliance The JFK-6A-R is designed to meet international safety standards to ensure the electronic components do not pose a fire or shock hazard: 1. **UL/cUL:** Recognized for the US and Canadian markets. 2. **VDE/ENEC:** European safety certifications. 3. **RoHS ("R"):** The "R" often confirms the part is Lead-free and compliant with the Restriction of Hazardous Substances. ---
