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.
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 (PM) and Battery Units (BU). Three different cabinets are available to build the system:
The Power Cabinets (PWC – 2 versions) and the Battery Cabinet. The Power Cabinets can accommodate either only the 25 kW Power Modules (PM25) or 42 kW Power Modules (PM42). The available UPS power and redundancy level can expand vertically using the PM25 power module from:
Also, power solution can expand vertically using the PM42 power module from:
Up to four complete Power Cabinets can be connected in parallel, increasing the capacity including redundancy respectively from:
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 (Combo Cabinet). 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.
The user might decide to build the solution using the combination of three PM either PM25 or PM42 kW power not mingling the two power rates in the same cabinet.
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.
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.
The entire 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 overall UPS 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 module is equipped with three
speed controlled fans to ensure tthere 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.
