Introduction
High performance, high reliability
telecom systems employ distributed
power modules to generate low voltage, high current supplies from a вЂ“48V
bus. These systems require that the
individual power modules are hot
swappableвЂ”they can be inserted
and removed at any time without
affecting the operation of the main
system. Another requirement is that
failed elements self-isolate without
affecting neighboring elements. The
system controller takes notice of any
failures and reconfigures the system so PLUG-IN BOARD + вЂ“48V RTN LTC4251 + CLOAD + ISOLATED
