UPS with battery backup and surge protection for electronics and computers. Automatic Voltage Regulation (AVR) gradually increases low voltage and reduces high voltage to a level suitable for your devices. Supports cold start and allows temporary battery operation when the power supply fails. The LCD graphic display shows operating modes, system parameters, and alarms in the form of text and overview diagrams. The pure sine wave output signal during battery operation simulates mains power supply for maximum compatibility with servers and sensitive electronic systems, featuring active power factor correction. Powerful safety features protect your home UPS from overloads, power surges, short circuits, installation errors, and battery damage due to undervoltage. Intelligent battery management with a smart precision charging system optimizes battery performance, lifespan, and reliability. Battery failure notifications enable analysis for early detection of battery faults for timely preventive maintenance.
