The powerful 1000VA UPS reliably protects 230VAC applications from power outages and input voltage fluctuations. Unlike conventional off-line UPS systems, the UPS-1000-B1 offers a sine wave voltage output, so that sensitive IT consumers such as industrial PCs, workstations, servers, network components as well as security and measurement technology are reliably supplied. The AVR function with buck/boost mode ensures automatic voltage regulation at the output of the UPS when the nominal voltage at the input is undercut or exceeded.
