12 Watt Dual Series Block Diagram
Description
These 10 and 12 Watt Dual Output DC/DC converters are
designed for telecommunications, medical or industrial
equipment and instrumentation systems.
The converters
feature very wide input voltage ranges.
The converter consists of a hi-speed chopper circuit using
state of the art MOSFET technology, isolation transformer,
and high regulation linear post regulator. This provides for
very low noise and ultra stable output voltages.
