Product Features D e s c ri p t i o n * The Erskine SMS1200 utilises high frequency switchmode technology to deliver a compact, efficient and reliable source of DC power. The system provides 1200A output at a nominal -48v DC in a single cabinet. The system comes complete with two 400A battery isolators and 6 outgoing distribution ways, each rated 100A. These can be linked to the Erskine End of Suite distribution board to provide expandable distributed power. * * * * * * * Real time monitoring and control is included in the form of the Erskine PMU (Power Management System) and PowerSentinel software.
