Power Entry Modules A power entry module combines the main AC inlet and common control and protection functions into a single, panelmounted unit so you can simplify wiring, save space, and improve serviceability. Key benefits Simplifies assembly: Integrates inlet, switch, fuse holder, and optional EMI/RFI filter or surge protection into one component to reduce wiring, soldering, and assembly time. Saves space: Compact panel cutouts and modular designs up internal chassis room for other components. Improves serviceability: Modular replacements make maintenance and field repairs faster—swap a single module rather than tracing multiple separate parts. Reduces EMC issues: Modules with integrated filters help limit conducted interference at the source, easing systemlevel compliance and troubleshooting. Enhances safety and reliability: Builtin fuse holders and switches provide clear protection and control points, reducing the chance of miswiring. Key attributes Function: Provides a standardized AC inlet and integrated control/protection elements (switch, fuse holder, filter options) in one unit for panel mounting. Compatibility: Designed for standard panel cutouts and IECcompatible inlet options; available in configurations for single or multiplepole switching and various fuse types to match common system requirements. Size and mounting: Compact footprints and frontpanel mounting formats minimize chassis intrusion; variety of profile depths to suit tight enclosures. Materials: Rugged, flameretardant housings and corrosionresistant contacts stand up to industrial and commercial environments. Performance options: Available with different current and voltage ratings and optional EMI/RFI filtering to meet system power and interference suppression needs. Practical applications Industrial control panels: multiple discrete inlet, switch and protection parts with a single module to reduce wiring errors and simplify assembly. Test and measurement equipment: Compact modules provide reliable, serviceable power entry with integrated filtering to reduce noise on sensitive circuits. Commercial appliances and office equipment: Streamline OEM production and field serviceability by using a single panelmounted power entry unit for power, switching, and protection. What to consider when selecting a module Required functions: Choose the combination of inlet, switch (single or multipole), fuse holder type, and filter or surge options that match your system needs. Panel cutout and mounting depth: Verify the module fits the intended panel thickness and available internal space. Current/voltage rating: Match the module ratings to the maximum operating conditions of your equipment. Environmental conditions: Select materials and contact finishes appropriate for ambient temperature, vibration, and humidity in the final installation. Serviceability: Consider frontaccess fuse holders or replaceable filter cartridges for faster maintenance. How it solves common problems Reduces assembly errors by consolidating multiple wiring points into a single, preconfigured module. Lowers risk of EMIrelated failures by providing integrated suppression options close to the inlet. Speeds field repairs through modular replacement instead of disassembly and rewiring. Ordering tips Specify the exact combination of inlet type, switch configuration, fuse holder style, filter option, and required electrical ratings. Confirm panel cutout dimensions and mounting depth before finalizing the selection. A power entry module is a practical, compact way to centralize AC power connection, control, and protection for a wide range of equipment, improving assembly efficiency, serviceability, and electromagnetic performance.
