Benefits of Liebert DS Direct Expansion as data center cooling systems
Smallest footprint 84 pole power distribution unit
Multiple configuration options allow optimization of data center space – two, three or four units may be installed in space-saving clusters.
Fits standard raised-floor tile, while permitting removal of adjacent floor tiles.
The 400A continuous current rated main circuit breaker better coordinates with today’s 30A and 60A branch breakers than smaller 225A mains, providing better selective tripping.
Each panelboard is totally isolated – any potential arc flash is contained within the cabinet when installed back-to-back and each is receiving a separate feed from a dual bus system.
Wide open access channels provide six inches of access space, and individual hinged covers, allowing easy addition of future circuits.
Compact cabinet conserves valuable floor space
Packaged system is easy to install, maintain and add additional circuits.
