The PM450 series comprising single and multiple output
models for 450-480 watts of continuous output power is
specially designed
support. They operate at 90 to 264VAC input voltage
without the need of a selector strap. The units are
constructed on a printed circuit board with a U-bracket for
mechanical support and heat sinking. A cover-and-fan
assembly can be added during manufacturing.

to master output dropping
5﹪ below its nominal value.
This signal also provides a
minimum delay of 100ms
after master output is within
regulation.
Requires an external TTL high
