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 suitable level 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. Pure sine wave output signal in battery mode simulates mains power supply for maximum compatibility with servers and sensitive electronic systems with 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: A smart precision charging system optimizes the performance, lifespan, and reliability of batteries. Battery failure notification: Analyses for early detection of battery faults enable timely preventive maintenance.
