Power Entry Modules A compact, allinone way to bring mains power into your product while simplifying wiring, improving safety, and reducing assembly time. Key benefits Simplifies integration: Combines inlet, switch, fuse holder, and optional EMI/RFI filtering into a single unit to reduce parts, PCB complexity, and assembly steps. Improves safety and compliance: Provides a standardized, secure connection point for AC mains and accepts common protective components (fuses, switches, filters) that help meet safety and EMC requirements. Saves space and time: Panel or PCBmount designs consolidate functions into a small footprint so enclosures stay compact and internal routing is minimized. Increases reliability: Purposebuilt mounting and electrical contacts reduce loose connections and strain on internal wiring compared with discrete wiring approaches. Core attributes Function: Integrates mains inlet with switching, fuse protection, and often EMI/RFI filtering and/or a voltage selector, offering a single interface for power entry and control. Compatibility: Designed to mate with standard IEC or regional inlet types and common fuses and switches; available in panelmount or PCBmount variants to match assembly methods. Size and mounting: Compact form factors for tight enclosures; options for snapin, screwmount, or boardmount installation to fit different mechanical designs. Materials and durability: Molded thermoplastic or reinforced insulating materials with metal contacts for longterm electrical integrity and mechanical strength. Performance: Engineered for reliable mains connection and low contact resistance; optional filters reduce conducted EMI to improve system performance in noisy environments. Practical applications Desktop and rack equipment: Use a power entry module to provide a professional, serviceable mains interface on power supplies, instrument enclosures, or rackmounted electronics. Industrial and control panels: Install panelmount modules to centralize fusing and switching for machinery, test benches, or process controllers while keeping wiring organized. Consumer and professional appliances: Integrate a power entry module into medical devices, office equipment, or laboratory instruments to offer safe, standardized power entry and easy replacement of fuses or modular switches. Why choose a power entry module for your design Reduces assembly cost and field service time by consolidating components. Makes compliance and testing easier by centralizing protective devices and EMI filtering. Offers predictable mechanical retention and electrical performance compared with ad hoc wiring. Provides a clean, userfriendly external interface for power, fuse access, and switching. Selection tips Match the inlet type (IEC or regional) and mounting style to your enclosure and assembly process. Confirm required protective elements (fuse type, switch rating) and EMI filter needs before selecting a module variant. Verify mechanical dimensions and panel cutout or PCB footprint early in the design to avoid rework. Ordering considerations Choose panel or PCBmount based on where the module will be installed. Specify required functions (e.g., fused inlet, illuminated switch, EMI filter, voltage selector) so the supplier can provide the correct variant. Request datasheets for mechanical drawings, electrical ratings, and certification information relevant to your application. A power entry module streamlines the path from mains to your circuitry while offering safety, serviceability, and reduced design complexity.
