One piece digital adjustable over and undervoltage protector for 230V systems, designed for DIN rail mounting and surge protection. It features a dual display for easy monitoring and configuration, providing reliable protection for connected equipment. Key benefits Protects equipment from damaging voltage swings: automatically disconnects when voltage rises above or falls below set limits, reducing the risk of brownouts, surges, and equipment failure. Easy configuration and monitoring: digital adjustable settings with dual display show both the actual voltage and the threshold settings for quick verification. Spaceefficient 2P design: compact twopole construction suitable for standard DIN rail installations in control panels and distribution boards. Reliable performance at 230V: specifically rated for 230V AC mains, offering dependable protection in common electrical environments. Available current options: supports 40A and 63A variants. Key attributes Current rating options: 40A and 63A variants (as indicated by the product line) Voltage: 230V AC operation Type: Digital adjustable over and undervoltage protector Display: Dual display for monitoring and configuration Mounting: DIN rail compatible Poles: 2P (twopole) design Protection: Surgecapable, designed to protect connected loads from voltage fluctuations Quantity: 1 piece per Compatibility and performance Suitable for integration in electrical panels, control cabinets, and distribution boards where DIN rail mounting is available. Performs as an automatic protection device for power supplies, motors, and other sensitive 230V equipment that require stable voltage within defined limits. Digital adjustability allows precise threshold settings to match the protection needs of diverse applications. Use cases Industrial control cabinet protection: safeguard PLCs, sensors, and drives from voltage spikes and sags by using the unit on the 230V mains feeding the panel. Office or lab equipment protection: shield computers, servers, and laboratory instruments from voltage fluctuations in environments with variable power supply. Home or small business power protection: protect essential electronics and entertainment systems from irregular mains voltage by integrating the device in the main electrical panel or project box on a DIN rail.
