Rack-mounted UPS extends to 300kVA in one cabinet

An Uninterruptible Power Supplies product story

Uninterruptible Power Supplies has again expanded its PowerWave 9000 UPS series.

Uninterruptible Power Supplies has again expanded its PowerWave 9000 UPS series.

New modules in the rack-mounted range make it possible to output up to 300kVA from a single cabinet with 1.22m2 footprint, or up to 200kVA with n+1 redundancy.

PowerWave 9000 was the first three-phase power protection system in a 19in rack, fully exploiting efficient third-generation transformerless technology to deliver substantial footprint and weight benefits.

By introducing new modules with power outputs up to 100kVA, Uninterruptible Power Supplies enables mature PowerWave 9000 technology to address applications in the highest power ranges, where space- and cost-saving benefits, together with low input harmonic distortion and power factor, make an even greater impact on installation and running costs.

Also at these higher powers, the costs and footprint penalty of implementing redundancy for highest system availability are again dramatically reduced.

A unique distributed parallel architecture enables cost-effective field upgrading for capacity or n+1 redundancy by the simple addition of further modules to a cabinet or by parallel connection of multiple cabinets.

Vertical and unlimited horizontal scaleability provide total flexibility for tailoring the power protection system to the load.

Furthermore, the ease of inserting or removing modules means that they can be hot-swapped.

In multiple-UPS cabinets, the units can be configured for capacity or redundancy operation, and include the intelligence to operate as either.

PowerWave 9000 features include 95% efficiency in on-line operation, input power factor of 0.98 for the lowest running costs of any UPS, and input current harmonic distortion less than seven percent for cleaner mains.

No 12-pulse rectification is required, further reducing capital costs.

A new feature in the latest introductions is a wide input voltage window, -40% to +15% at 60% load, limiting battery usage in applications with a very unstable mains supply.
