Multi-Power MPW & MPX

Modular AC Uninterruptible Power Supply with Hot-swap Batteries

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.

Scalability

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 (MPW and MPX type) and the Battery Cabinet (BTC). The Power Cabinets can accommodate either 15 kW (MPX 15 PM), 25 kW (MPX 25 PM) or 42 kW Power Modules (MPW 42 PM). The available UPS power and redundancy level can expand vertically from:

  • 15 to 75 kW in one single Power Cabinet (MPX 130 PWC with MPX 15 PM)
  • 25 to 125 kW in one single Power Cabinet (MPX 130 PWC with MPX 25 PM)
  • 42 to 294 kW in one single Power Cabinet (MPW 300 PWC with MPW 42 PM).

Up to four complete Power Cabinets can be connected in parallel, increasing the capacity including redundancy respectively from:

  • 75 up to 300 kW (with MPX 15 PM)
  • 125 up to 500 kW (with MPX 25 PM)
  • 294 up to 1176 kW (with MPW 42 PM)

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 Multi Power is available as an optimized solution providing a Multi-Power/Battery combination with the Combo Cabinet (MPW and MPX type).

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 MPW 42 PM and five battery shelves (MPW 130 CBC) or four MPX 15 PM / MPX 25 PM and six battery shelves (MPX 100 CBC) not mingling the
two power rates in the same cabinet.

 

Outstanding Performances

  • The advanced technologies deployed within the 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 of 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 subsequently reduced investment 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). Multi-Power is compatible with the very latest operating systems.

Flexible Modularity

Multi-Power grows both vertically and horizontally from 1 to 20 Power Modules (MPX 15 PM/MPX 25 PM) or 1 to 28 Power Modules (MPW 42 PM) up to 1176 kW (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 inconvenient 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 (inbuilt contactor is optional for MPX 130 PWC and MPX 100 CBC). Combination systems (Combo Cabinet) and 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.
