Riello UPS Multi Power Information

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 Riello UPS 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 and associated packages. Rather than using standard components that are readily available in the marketplace, the Multipower 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.

Riello UPS Multi Power provides a comprehensive, easy-to-integrate power protection solution for data centres 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 (Uninterruptible Power Supply) power and redundancy level can expand vertically from 42 to 294kWin 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 from294kW 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 Riello UPS MPW is available as an optimized solution providing a Riello UPS 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.

Outstanding Performances

  • The advanced technologies deployed within the Riello UPS MPW guarantees full rated power even with unity power factor loads(kVA=kW) without any power downgrading even when operating at temperatures up to 40°C.
  • High system efficiency whilst operating in on-line double-conversion mode greater than 96, 5%. Even when loaded at only 20%, the MPW still achieves an outstanding performance greater than 95%. This superior performance ensures extremely low losses at any load level whilst maintaining a true modular solution for any changing UPS environment in terms power demands.
  • Low input harmonic pollution, with near unity input power factor and an extremely wide input voltage operating range (+20/-40%), requiring only a minimum upstream power source rating and subsequent reduced investment costs.

Multiple Controls
The entire Riello UPS Multi Power solution was developed with particular care to ensure operational reliability and prevent any possible failures due to miscommunication between the component parts of the system.
The Power Modules are not controlled by one unique microprocessor, but by three - each having different and specific duties. Likewise, the Power cabinet features two separate microprocessors; one to regulate the operations and a separate one to manage communication with the user.
In addition, three dedicated communications bus manage and transmit the data. In terms of the monitoring and control of the overall system, all major components are continually temperature monitored within each of the Power Modules. In addition, up to four temperature sensors are embedded within the Power cabinet to ensure constant and efficient operation. The UPS (Uninterruptible Power Supply) module is equipped with three speed-controlled fans to ensure there is no energy wasted as the load level applied to the system increases or decreases. At the same time, each fan features a so-called third wire (the controller) which immediately warns the microprocessor in the event of a fault; in which case the microprocessor will increase the speed of the remaining operational fans in order to compensate for the cooling deficiency. The Battery unit also contains dedicated internal protection and a sophisticated control system to monitor the status of each module. This makes it possible to check the voltage/current supplied by each single battery module and therefore identify and warn the user if one of them is defective or beginning to fail. This significantly reduces the risk of a battery pack failure causing a problem to the system by immediately warning the user of the impending issue in order for the appropriate preventive actions to be taken before it is too late.

Flexible Modularity
The Riello UPS 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 Back feed 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.

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). The Riello UPS Multi Power is compatible with the very latest operating systems.
