Energy saving: The device automatically interrupts power to lighting and connected components when the door opens, then restores power when it closes, cutting idle energy use. Component protection: By reducing run time for bulbs and electronics, it helps extend component life and lowers maintenance. Comfortable light control: Lights switch on automatically on door open and off on door close, with no manual operation required. Condensation control: Power to cooling components is paused while the door is open, reducing condensation inside the cabinet. Why it works better: - Function: automatic, door-sensor based switching for reliable hands-free operation. - Compatibility: designed to work with standard door sensors and lighting circuits in display cases, refrigerators, freezers, and cabinets. - Size and material: compact retrofit module with a durable enclosure for easy installation in tight spaces. - Performance: fast response, low energy draw, and proven reliability. Use scenarios: - Supermarket cold display case: keeps lighting and climate control efficient while customers browse. - Hotel minibar or guest room cabinet: ensures lighting works automatically without leaving doors open or lights on. - Pharmacy or high-value retail cabinet: protects components and minimizes condensation for clear viewing.
