Multi Power2 is the evolution of Riello UPS’s modular solutions. It is designed to deliver smart, scalable, sustainable power to high-density computing environments such as data centers and similar mission-critical settings.

Manufactured with state-of-the-art technologies, including 3U 67 kW power modules, Multi Power2 delivers best-in-class power density and market-leading ultra-high efficiency of up to 98.1 percent in online double conversion mode.

This minimizes data center operators’ running costs, energy losses, and cooling requirements while still delivering high availability, reliable performance, and outstanding flexibility.

The Multi Power2 range incorporates the 500 kW MP2 model and the scalable M2S, which comes in 1000-1250-1600 kW versions. It builds on the successes of Riello UPS’s original and best-selling modular UPS Multi Power, which has been protecting critical loads in data centers throughout the world for nearly a decade.

Multi Power 2’s new power modules offer double the power density of previous iterations and are designed to be fully hot-swappable and mechanically segregated to avoid any single point of failure, minimizing the mean time to repair (MTTR). It also offers simple, risk-free ‘pay as you grow’ scalability that optimizes both the initial investment and total cost of ownership.

Leo Craig, managing director of Riello UPS Ltd, commented: “Multi Power2 is the evolution of our modular UPS solutions, which offers unbeatable operating efficiency, higher power density, easier integration, and unparalleled flexibility.

“There’s an increased emphasis in the data center industry on sustainability and energy saving, and the Multi Power2’s advanced technologies truly raise the bar and will help reduce operators’ carbon footprint while improving their efficiency and cost-effectiveness, making them more sustainable in the long-term.”

Multi Power2 embraces the use of state-of-the-art silicon carbide (SiC) semiconductors, which offer several advantages compared to the traditional silicon-based IGBT components used in UPS manufacturing:

  • Higher efficiency: SiC components exhibit lower electrical resistance, resulting in reduced energy losses, which helps to maximize the overall efficiency of the UPS.
  • Increased power density: the technology enables increased power density, making it possible to design more compact and lightweight UPS systems without compromising on power capacity.
  • Increased thermal stability: SiC can operate at higher temperatures, translating to a broader operational range and reduced cooling demands.
  • Enhanced frequency response: SiC's faster-switching capabilities result in a more responsive UPS system, crucial for handling the rapidly changing load conditions typically found in modern data centers, particularly those dealing specifically with AI applications.
  • Durability: the robustness of SiC reduces wear and tear, leading to extended component and UPS lifecycles along with reducing maintenance needs.

These benefits enable Multi Power2 to deliver cost, energy, and carbon emissions savings when replacing both old legacy monolithic UPS systems and the standard modular solutions currently available from other manufacturers.

The following are two actual total cost of ownership (TCO) calculations provided to data centers in the process of upgrading their UPS.

Comparison 1 outlines the savings from replacing a monolithic 1 MW N+1 UPS system (made up of 3 x 12 pulse 600 kVA 0.9pf UPS) with a 1,250 kW Multi Power2.

  • Total annual energy cost saving = £95,759.65 (US$122,939.11)
  • Overall total annual cost saving = £117,544.13 (US$150,906.68)
  • Total annual CO2 saving = 148.7 Tonnes
  • Total 15-year cost saving = £2,353,655.21 (US$3,021,693.17)
  • Total 15-year CO2 saving = 1702.8 Tonnes

Comparison 2 highlights the savings delivered by a 1,250 kW Multi Power2 at 1 MW load versus another manufacturer’s latest modular offering, with their system comprising 3 x 400 kVA modular units.

  • Total annual energy cost saving = £51,099.24 (US$65,585.62)
  • Overall total annual cost saving = £53,839.91 (US$69,103.26)
  • Total annual CO2 saving = 79.4 Tonnes
  • Total 15-year cost saving = £1,078,068.22 (US$1,383,431.04)
  • Total 15-year CO2 saving = 908.7 Tonnes

In addition to these topline cost savings, the long-life components used in Multi Power2 offer further advantages.

With most traditional UPS, capacitors usually need replacing around years 5-7 of service life, so will need swapping out two or three times over a typical 15-year lifespan. However, with Multi Power2 it is realistic to go through the entire product lifespan without replacing the capacitors at all, a significant cost saving plus fewer end-of-life components that require recycling.

All in all, a typical data center could save around £80,000-£120,000 (US$103,000-154,000) in maintenance costs over the complete lifespan of the UPS. This figure doesn’t even consider additional knock-on environmental benefits such as reducing the number of miles engineers will travel because of fewer required maintenance visits.
