The Riello MULTI POWER (MPW) is the ultimate modular UPS for DATA CENTRES and other CRITICAL LOADs.The MULTI POWER is designed to protect any critical high-density computer and IT environment, whilst achieving maximum availability. The MPW grows along with the demands of the business without oversizing the UPS – optimizing both the initial investment and the Total Cost of Ownership. As soon as demand increases, the Riello MPW modular solution can expand its power capability, maintaining the highest levels of power protection, availability, redundancy and investment savings.

Digital technology has an increasingly strong influence on day-to-day activities in almost all sectors and applications such as healthcare, power generation, social networking, telecommunications, commerce and education.Subsequently, any activities and equipment related to data storage, processing and transfer should be supplied from the most reliable power source. Multi Power ensures that a scalable, secure, high-quality power supply is available for a variety of critical load applications. The new MPW Power Modules feature the very latest in UPS technology. With its three level Neutral Point Clamped (NPC) inverter and Power Factor Corrected (PFC) input control, the MPW ensures the highest level of performance in terms of overall efficiency, input power factor and harmonic impact on the supply source.

Flexible Modularity: Multi Power grows both horizontally and vertically from 1 to 28 Power Modules increasing from 42 to 1176kW (including redundancy) as well as battery units (from 1 cabinet up to 10), therefore the system is completely scalable in accordance with any business requirements.

The Plug & Play modular concept simplifies any power or battery autonomy expansion process, rather than a complete Power Module or Battery unit replacement. The modular hot-swappable principle is further extended to all major elements of the system, resulting in convenient replacement of parts such as fans from within individual Power Modules rather than accessing major components within the cabinet. Furthermore, all power modules and critical components are easily accessible from the front of the unit as standard. The system is equipped with a Manual bypass change over switch and Backfeed control with a mechanical interlock contactor inbuilt, eliminating any maintenance-related downtime.Combination systems (Power cabinet with Battery cabinet) are supplied with a battery switch and shunt trip to enable remote battery switch operation.

Advanced Communications: Users can benefit from the different communication systems developed specifically for IT personnel, facilities managers and service engineers. The 7”LCD touch screen, communication slots, relay cards along with the dedicated service ports, all ensure that the UPS setup, control and monitoring is easy, along with the integration into any building management system and data centre infrastructure management (DCIM). Multi Power is compatible with the very latest operating systems.
