UPS data center, uninterruptible power supply data center
Data centers represent one of a company's most fundamental assets: a structure on which the entire organisation depends.
This is why it is important to ensure these systems are both functional and reliable, starting from the correct electrical layout of the system and following precise quality criteria.
Availability
According to the TIER standard, system availability should fall between 99.9 and 99.999%: downtime is not an option. Using high quality Riello UPS uninterruptible power supplies in a well-designed system, this level of availability can be achieved. The UPS must be versatile, compact and parallelable in order to provide the required flexibility; they should be able to adapt to all types of load, both inductive and capacitive, and should also be able to integrate with the other components in the system (e.g. electrical generators).
Energy consumption
Reducing energy consumption has become a necessity for all businesses as well as an environmental concern. It is therefore fundamental to choose a UPS supplier that offers green products designed to provide the best energy efficiency and lowest environmental impact possible, with maximum performance. The Eco Energy Levels help identify the most highly efficient Riello UPS products.
Physical space
It is critical optimise the space available in data centers. Virtualising servers helps, but it is also useful to choose UPS with small footprints in order to avoid wasting space. The Multi Sentry , Sentryum (Compact, Active, Xtend, flexibility of autonomy and dimensions), Multi Power (MPW and MPX, modular solutions), NextEnergy (trasformer-free solution) and Master HE UPS ranges have the ideal dimensions.

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.
