The LineSecure III UPS series with intelligent design and pure sine wave output for connected applications is the best choice for office, SOHO and home applications. It offers a high quality pure sine wave output for connected critical devices. Additionally equipped with an AVR (Automatic Voltage Regulator) that stabilises fluctuating voltages such as over and under voltages and other voltage problems and provides a stable output voltage for the most important devices. The LS III series is equipped with a colour LCD display that shows the UPS status and increases user-friendliness. The LS III series offers power protection, including overload, overvoltage and short circuit protection. Through the USB port, it enables UPS status monitoring, UPS event scheduling and instant notification via a computer system or portable device. It also has a slot for an SNMP/web card.In areas with strong voltage fluctuations, the UPS regulates the differences between the input voltage and the target voltage using buck and boost control. The battery management monitors the batteries of the UPS and only charges them when necessary; this extends the service life of the batteries by up to 50%.
