Automatic door-controlled power and lighting module for refrigerated and display doors Key benefits Energy savings: When the door opens the unit interrupts power to cooling components; power is restored when the door closes. This reduces unnecessary compressor/cooling runtime and lowers energy use during access periods. Component protection: By preventing extended operation of lamps and cooling equipment while the door is open, the module reduces wear and extends the service life of bulbs, compressors and related components. Comfortable, hands-free lighting: Interior lighting turns on automatically when the door opens and off when it closes, so staff and customers do not need to operate switches manually. Reduced condensation: Stopping the cooling components during door-open periods reduces condensation buildup on products and cabinet surfaces, improving product visibility and hygiene. Core functions and compatibility Function: Automatic door-triggered power control for cooling circuits combined with automatic lighting control for interior lamps. Compatibility: Intended for use with lighting circuits, lamp types and cooling components commonly found in refrigerated display cases, commercial refrigerators and similar door-mounted cooling systems. Performance: Improves energy efficiency during access, lowers component operating hours, and reduces condensation-related problems without manual intervention. Installation: Designed to integrate with door switches and standard control wiring used on refrigerated display cabinets and similar equipment (check device wiring and safety requirements before installation). Practical applications Supermarket or convenience-store refrigerated display: Keep shelves visible with lights on while pausing cooling during customer access to reduce fogging, energy use and compressor cycling. Walk-in coolers and laboratory cold storage: Provide automatic interior lighting for safe access while reducing unnecessary compressor runtimes and condensation on sensitive items. Food trucks and mobile refrigeration: Improve interior visibility during service and protect cooling and lighting components from excessive run-time. What customers should expect Hands-free operation synchronized with door position: automatic off/on behavior for lighting and cooling circuits tied to door open/close events. Reduced energy consumption and fewer hours on lamps and cooling components, which can translate to lower operating costs and longer component life. A practical retrofit or integration option for equipment that requires automatic control of lighting and cooling during door access events. Note: Verify compatibility with your specific electrical and control systems and follow applicable safety and installation standards when integrating this module into refrigeration or display equipment.
