The FND300-1012G is a highly-efficient bus
converter with one high current output, which
can be used in a wide range of applications.
Passive current share along with internal
ORing diodes allow this unit to be also used in
redundant, hot-swap applications.
The FND300 meets international safety
standards and displays the CE Mark for the
Low Voltage Directive.
