The Riello STW 6000 series is the Sentinel Tower is the ideal solution for protecting mission-critical systems such as safety devices, telecommunications equipment but also IT systems to ensure maximum power reliability. Sentinel Tower is designed and built using state-of-the-art technology and components to provide maximum protection to the powered loads with no impact on downstream systems and optimised energy savings. The series includes 5-6 kVA single/single-phase and 8-10 kVA single/three-phase input single-phase output models with ON LINE double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of form and frequency. In terms of technology and performance, Sentinel Tower is one of the best UPS available on the market today: three-level inverter to achieve 95% efficiency, output power factor 1 to increase in efficiency of system and devices and reduce power system losses.
