An online double-conversion UPS provides the highest level of power protection. It continuously converts the incoming AC supply to DC and then inverts it back to AC, so the connected load always runs from the inverter and is completely isolated from the mains. This removes every class of power disturbance, including voltage sags and surges, frequency variation, harmonics, and electrical noise, and it switches to battery with zero transfer time when the mains fails. Online double-conversion UPS systems are the standard choice for servers, storage, data centres, medical equipment, and industrial control systems that cannot tolerate any interruption or unclean power.
Natural Power Solutions supplies online double-conversion UPS systems from APC by Schneider Electric, Eaton, Socomec, and Vertiv, in single-phase and three-phase configurations from 500 VA to 600 kVA. For smaller offices and equipment that can tolerate a very short transfer time, our line-interactive UPS range is a lower-cost alternative. For process-critical industrial loads such as motors and variable speed drives, see our industrial UPS range.
