Erskine Systems Limited reserve the right to alter
this specification at any time without notice.
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.
