Power Entry Modules What this product does Provides a single, compact interface to bring mains power into your equipment. Combines the functions you need at the equipment boundary — inlet, switch, fuse holder, and optional EMI/RFI filtering — so installation is faster and wiring is cleaner. Why customers choose a Power Entry Module Simplifies design and assembly: integrates multiple power components into one footprint, reducing panel cutouts and wiring time. Improves reliability and safety: factorymounted connections and captive components reduce loose wiring and assembly errors. Streamlines sourcing and approvals: a single module reduces the number of separate components to manage in procurement and BOMs. Key benefits and problem solving Space savings: replaces separate inlet, switch, and protection devices with a compact module that fits standard panel cutouts or small chassis openings. Faster assembly and maintenance: fewer parts and standardized mounting make installation and replacement quicker and less errorprone. Cleaner design and improved EMI performance: modules with integrated EMI/RFI filters reduce conducted interference without extra board space or external filters. Better mechanical integrity: rugged housings and secure terminals resist vibration and handling during production and service. Important attributes (concise) Function: integrates mains inlet, on/off switch, fuse holder, and optional EMI/RFI filter and/or appliance rocker switch in one unit. Compatibility: available in multiple mounting styles and panel cutouts to match standard chassis and panel designs; compatible with common line voltages when properly specified. Size: offered in compact to standard form factors to fit constrained or conventional enclosures; reduces the number of separate cutouts. Material: durable thermoplastic or engineered polymer housings with secure terminals for reliable electrical connections and mechanical strength. Performance: designed for rated mains currents and to accommodate typical inrush currents; EMIequipped modules reduce conducted noise for sensitive electronics. Practical use scenarios Industrial control panel: separate inlet, switch, and fuse components with a single Power Entry Module to reduce assembly time, simplify wiring, and panel space for other controls. Medical and laboratory equipment: Use a module with integrated EMI filtering to meet conducted emission requirements while keeping the front panel clean and servicefriendly. Benchtop and rackmounted instruments: Install a compact Power Entry Module to provide a reliable mains connection, an accessible power switch, and an easytoservice fuse holder without redesigning the chassis. Installation and service considerations Choose the correct module for your panel cutout and mounting style to avoid rework. Select modules with the appropriate fuse holder type and fuse rating for your device's protection needs. If EMC/EMI suppression is required, select the module variant with an integrated filter and verify compatibility with your conducted emission targets. For reliability or vibration applications, select modules with reinforced terminals and robust housings. Why this solution stands out Integration reduces part count and simplifies both design and aftersales service. Replacing multiple discrete components with a single, purposedesigned module lowers the risk of assembly error and improves product consistency. Modular options (filters, fused or unfused, detachable cords) allow tailoring to the exact needs of your product without redesigning the chassis. Selecting the right Power Entry Module Confirm the required mains voltage and current ratings for your equipment. Identify whether you need an integrated EMI/RFI filter, fused or unfused entry, switch type, and preferred mounting cutout. Match the mechanical footprint and terminal style to your production and service processes. If you need assistance choosing the correct Power Entry Module for your application, specify your panel cutout, current and voltage requirements, and any EMI or fuse preferences to ensure the right fit and performance.
