Power Entry Modules Power entry modules provide a compact, integrated solution for bringing mains power into equipment and controlling that power safely and reliably. Key benefits Simplifies system design by combining inlet, switch, fuse holder, and optional filtering into a single mounting unit Improves safety and reliability by centralizing protective and switching functions at the power entry point Saves assembly time and panel space compared with discrete components Reduces electromagnetic interference and improves power quality when a filter option is used Eases service and replacement with a single, accessible unit What it does Controls and protects incoming AC mains power with integrated switching and overcurrent protection Provides a consistent, standardized interface for power connection to appliances and equipment Can include optional EMI/RFI filtering to meet conducted emissions requirements Important attributes Function: combines power inlet, switching, and protection in one module for straightforward integration Compatibility: designed to be mounted at the equipment power entry point and to interface with common internal wiring practices Size: modular form factor minimizes panel cutout area and supports compact enclosure design Material: rugged housing and reliable contact materials are used to withstand repeated use and provide stable electrical connections Performance: engineered for dependable operation under normal mains conditions; specific ratings vary by model and should be confirmed against application requirements Practical applications Industrial control cabinets: centralize mains connection, on/off control, and fuse protection to simplify wiring and maintenance Test and measurement equipment: reduce bench footprint and provide a single access point for power and safety functions Office and IT equipment: integrate power inlet and switch functions for compact power distribution units and small UPS systems Selection and installation tips Match the module's electrical ratings and protection features to your equipment's input current and safety requirements Verify the mechanical cutout and mounting style against your enclosure or panel Consider filter options if conducted emissions or noise suppression is a concern Follow applicable safety standards and installation instructions for mains wiring and grounding For reliable, spacesaving power entry and protection, a power entry module consolidates essential input functions into a single, serviceable component, simplifying assembly and maintenance while improving safety and system organization.
