Sentinel Tower
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. Input and output filters provide significant further immunity from main disturbances and lightning strikes. 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. Selectable ECO Mode and SMART ACTIVE Mode functions; new custom diagnostics LCD display, RS232 and USB interfaces with Powershield³ software, ESD input, interface slot with optional boards.
