Description
Applications
HD Brick Series DC-DC Converters are isolated, regulated,
and operate from an unregulated, wide range input to
generate an isolated output.
Industrial and process control, distributed power, ATE,
communications, defense and aerospace.
With its high frequency zero voltage switching (ZVS)
topology, the HDC consistently delivers high efficiency
across the input line range. Modular HDC and downstream
DC-DC products support efficient power distribution,
providing superior power system performance and
connectivity from a variety of unregulated power sources
to the point-of-load.
