New Multi Power 1-28 x 42 kW up to 1 MW + redundancy UPS

Published by Jason Koffler on 25 April 2015

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.

Advanced Technology

To ensure the highest levels of power availability, only the most reliable, cutting edge power components and innovative control technologies have been used in the development of the MPW power modules and other major aspects of the system. The major power components and assemblies within the MPW have been specifically designed and tailor made in conjunction with the respective component manufacturers. This design work ensures that the MPW achieves the highest levels of power and performance. In order to optimize the overall performance of the finished product, Riello’s R&D team made the decision to specifically design certain power components, including the IGBT modules and associated packages. Rather than using standard components that are readily available in the marketplace, the Multi Power hosts one single optimised and reliable power assembly which guarantees the best availability and overall efficiency.
The Power Module itself utilizes a “wireless power principle” meaning that the power interconnection distances between the cards, power components and connectors are shorter. In this way we reduce any risk related to connection problems between the assemblies and also minimize the overall power losses.


Multi Power provides a comprehensive, easyto- integrate power protection solution for data centers and any critical IT application matching the evolving demands of a networked environment.
The end user can easily increase power, redundancy level and battery autonomy by simply adding additional UPS Power Modules and Battery Units.
Two different cabinet frames are available to build the system: The Power Cabinet and the Battery Cabinet.
The available UPS power and redundancy level can expand vertically from 42 to 294kW in one single Power cabinet (1 to 7 Power Modules including redundancy). Similarly up to four Power Cabinets can be connected in parallel, increasing the capacity from 294kW up to 1176kW. The Battery cabinet accommodates multiples of 4 battery units, with up to 36 units within a single frame with a maximum of 10 Battery cabinets connected in parallel.
In addition, the MPW is available as an optimized solution providing a Multi Power/Battery combination with three UPS Power Module slots and five battery shelves. This solution can be utilized within extremely compact areas requiring a small footprint with maximum power density. This modular and reliable solution is perfect for any small to medium business applications.

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.
All these features ensure easy UPS expansion, operation and maintenance; minimizing downtime, decreasing the Mean Time to Repair (MTTR) and removing any possible risk to power continuity, when carried out by authorized service personnel. Flexibility is measured by the ease of both on site installation and the operations undertaken by the user. Input/Output/battery terminal bars are deployed enabling authorized installers to easily terminate the cables either from the top or the bottom of the system. Mechanical supports and cable glands as well as the terminal bar positioning (in the centre of the cabinet) are purposely positioned to reduce the installation time and costs.
