Power Entry Modules Power entry modules provide a single, compact interface for bringing mains power into equipment while integrating common protection and control features. They reduce assembly time, simplify wiring, and make service easier by combining inlet, switch, fuseholder, and optional EMI/RFI filtering into one mounted unit. Key benefits Simplifies system design: combines multiple power functions into a single module to reduce wiring, component count, and assembly time. Improves safety and serviceability: integrated fuseholders and switches make it easier to isolate and protect circuits and to fuses without opening the enclosure. Reduces electromagnetic interference: modules with builtin EMI/RFI filters help meet conducted emissions requirements and improve system reliability in noisy environments. Saves panel space: compact, panelmount designs consolidate functions into a single cutout and up internal space. Reliable performance: robust contacts and temperature housings provide longterm durability for continuous operation. Primary functions and typical attributes Functions: mains inlet, manual on/off switch, fuseholder, and optional EMI/RFI filter and IECstyle connectors are commonly combined to provide a tailored interface. Compatibility: designed to mate with standard mains connectors and fit common panel cutouts, making them suitable for a wide range of equipment and wiring practices. Size and mounting: compact, panelmounted modules minimize required frontpanel space and simplify mechanical integration. Materials and construction: durable thermoplastic or thermoset housings and plated conductive contacts provide mechanical strength, electrical reliability, and heat resistance. Performance considerations: available configurations support typical mains wiring, provide protection through fusing and switching, and offer filtering options to reduce conducted emissions. Use scenarios Industrial control cabinets: consolidate inlet, switch, and fuse functions into one mounted module to simplify wiring and speed maintenance during service calls. Bench and lab equipment: provide a neat, serviceable mains interface with integrated fuseholder and switch while reducing conducted interference that can affect sensitive measurements. Commercial appliances or test systems: standardize power entry across product lines to reduce parts inventory and streamline assembly. Installation and selection tips Choose a configuration that matches required functions (inlet only, inlet + switch, inlet + switch + fuseholder, with or without EMI filter). Verify panel cutout dimensions and wiring polarity to ensure proper fit and safe connection. Select materials and ratings appropriate to your operating environment and duty cycle. Power entry modules simplify mains integration, improve safety and serviceability, and help control conducted emissions without increasing panel footprint.
