Schneider Electric extends Easy UPS 3-phase UPS range up to 600kVa

Schneider Electric has expanded its Easy UPS 3-phase Uninterruptible Power Supply (UPS) range to 500 and 600 kVA (400V) for external batteries.

The new Easy UPS 3L is aimed at medium and large commercial buildings, data centres, and light industrial UPS applications where critical equipment needs to be protected from power outages, surges, and spikes.

Spacewalking astronauts install lithium-ion batteries on ISS

Astronauts performed their second spacewalk in under a week to replace old batteries outside the International Space Station.

Commander Chris Cassidy and Bob Behnken ventured out to tackle the big batteries.

For every two outdated batteries coming out, a new and improved one goes in to supply power to the station on the night side of Earth.

Riello UPS extends NextEnergy range with 500 kVA edition

Riello UPS has expanded its NextEnergy (NXE) series with a more powerful 500 kVA model.

Riello said the new NXE 500model incorporates the latest transformerless technologies to deliver TÜV-certified operational efficiency up to 97 percent in online UPS mode, helped by its Efficiency Control System which minimises wasted energy at partial loads.

Rolls-Royce and Daimler Truck AG team up on fuel-cell generators for data centres

Rolls Royce and Daimler Truck AG plan to collaborate on fuel cell generators for data centres, with the companies planning to launch a demo system later this year.

The fuel cells themselves will be supplied by Daimler Truck AG, one the world’s largest commercial vehicle manufacturers, and fellow automaker group Volvo.

Last year both companies signed a preliminary agreement to manufacturer the energy devices on a large scale.

Is too much power capacity in data centres going to waste?

Data centres exist to deliver IT workloads in a manner that is both capital and energy-efficient, in this way both data centre and customers benefit. Yet the power delivery method remains rigid, inflexible and usually misaligned with IT SLAs, which has a significant negative impact on performance and infrastructure capital efficiency.

For many in the data centre sector, one of the most pressing concerns is that much of the world’s data centre infrastructure operates in a manner that is financially suboptimal and environmentally unsustainable. While there is steady capital inflows to the data centre sector some are questioning whether data centres are as capital efficient as they could be. If a data centre is only using a fraction of the available power then the capital investment that is tied up in inflexible power infrastructure is impotent. The question is, who is paying for that stranded capacity and unused space?
