PILLER UB-V ELECTRICALLY-COUPLED UPS FOR DATA CENTRES

Introducing Piller’s new high-performance UB-V ELECTRICALLY COUPLED (EC) UPS series for the conditioned power protection needs of cloud hyperscale build-outs, power provision in wholesale colocation and large enterprise deployments. 

The Piller UNIBLOCK™ UB-V is a flexible solution providing up to 3.24MW of UPS in a single module to give higher reliability compared with large scale static deployments and better availability through significantly extended preventative maintenance service intervals and fewer corrective shutdowns. 

Piller UB-V UPS features a new control platform incorporating self-diagnostics for predictive maintenance and continual peace of mind. Piller’s eVENTLOG™ is a new trademarked remote maintenance monitoring package. It can make annual service shutdowns a thing of the past and push off-line maintenance intervals to five years.

Build-out growth rates of new generation data centres make it vital to maximise capital investment from day one

PROVIDING POWER STABILITY AT SCALE

Most data centres are powered by electrically coupled (EC) UPS in one of two forms. An EC UPS connects the energy store with the UPS unit using an electrical connection via a DC link. Power semiconductors are used to control the energy flow for both discharging and recharging. The energy store may be either a battery or a kinetic energy source. Electrically coupled UPS include static and UB-V technology.

Piller’s high performance UB-V UPS is a new generation EC UPS. It is designed for flexibility, availability and reliability while providing capital cost control and maximised operating efficiency. As hyperscale cloud companies, large colocation investments and enterprise demands drive growth in the global data centre market, the use of battery backed, EC UPS systems continues to grow.

ELECTRICALLY COUPLED UB-V SERIES UPS BENEFITS
The UB-V series unit’s power ratings range from 1100kVA 1.0MW to 3600kVA 3.24MW in both battery and kinetic energy storage versions, making them ideal for large scale deployment.
Piller UB-V solutions are designed for renewable and sustainable energy sources with bi-directional power flow for feeding energy back to the grid. Online mode efficiency is typically higher than that for static UPS in the operating range above 35% – thereby reducing energy costs without compromising protection.
The UB-V series utilises fewer components and eliminates component wear on parts such as power capacitors which in turn reduces maintenance requirements and dramatically increases reliability.
The scale of Piller’s UB-V units removes the need for multiple module paralleling to achieve higher power ratings. Less paralleling can also provide better reliability and higher availability in the power string of large data centres.
UB-V systems can save on space and capital infrastructure cost. They can operate at low or medium voltage levels to give greater flexibility in scheme design as data centres continue to grow.

CLOUD, CO-LO AND ENTERPRISE

For wholesale colocation companies who build and operate data centres at scale to service high-end business-critical workloads for multiple commercial and enterprise customers, reliability and uptime are paramount. The same is true for hyperscale firms offering cloud platform infrastructure and business applications at the highest scale.

At every level colocation managers and their cloud peers must be highly responsive to customer needs for flexible power and varying power densities. They must ensure maximum operational efficiency and the highest possible availability at all times.

The provision of dedicated space, power and cooling at scale needs widespread redundant power which is both stable and flexible.

Piller’s UB-V EC UPS power infrastructure is specifically designed to meet all these supplier and customer needs.

CAPITAL EFFICIENCY OF UB-V

Hyperscale companies are driven by the quest for ever greater efficiency in every area. Build-out growth rates of new generation data centres make it vital to maximise capital investment from day one of operation.

As enterprises increasingly shift workloads to the cloud and as cloud-based digitally native firms expand, fierce competition among cloud providers further increases the need for cost control and capital efficiency.

Piller UB-V series has been designed with reduced infrastructure capital costs firmly in mind. The more its power rating rises, the more favourable the capital costs per kW become. With a relatively small physical footprint compared to typical static systems, the UB-V UPS can save more than 20% of data centre technical white space, thereby freeing up revenue-generating real estate.

UB-V offers significant space savings compared to other UPS.

OPERATIONAL EFFICIENCY

Not all UPS are the same. In many ways, electrically coupled rotary UPS systems can be said to be more reliable and more efficient than their static counterparts.

In efficiency terms, the UB-V UPS with a battery power source compares favourably with static UPS. UB-V, provides on-line efficiency of up to 98% at 100% load and 97% at 50% load, against static UPS which typically operate around 96.3% efficiency at both 50% and 100% loads.

Like for like comparisons between UB-V electrically coupled UPS and mainstream static UPS solutions in online mode show the UB-V provides greater efficiency across much of the operating load range, especially at higher ratings.

e-VENTLOG™. The Piller UB-V UPS series is equipped with an innovative new communication system and process. It monitors multiple operating and predictive maintenance parameters and can communicate system behaviour directly to an operation centre.

In controlled environments e-VENTLOG™ can completely eliminate the need for operational shutdown of the UPS for up to five years.

UB-V EC UPS BENEFITS OVER STATIC UPS
The UB-V UPS series has been designed without power capacitors or electric fans and has no internal paralleling of power strings, the mean time between failure of a single unit rises by a factor of 5 (hundreds of thousands of hours to millions) when compared with the failure rates of a typical static UPS.
Static UPS use for large scale data centres means paralleling many low power modules. With the UB-V UPS series the smallest unit delivers 1.0MW and a single unit can provide 3.24MW of conditioned power.
UB-V higher reliability reduces, and in some cases eliminates, the need for physical interventions in the servicing of UB-V EC UPS compared with strict annual or even twice-yearly servicing regimes required by some UPS systems.
The UB-V UPS series can easily be employed at either low or medium voltage and can be utilised with upstream or downstream standby generators.
For long term sustainability, UB-V technology has been specifically designed to work well with renewable/alternative energy sources. It provides both stabilisation and bi-directional power flow for feeding energy back to the utility.

A 48MW data centre equipped with UB-V EC UPS can save almost $5 million in electricity costs over ten years
