ply has sufficient current rating at minimum input
voltage for the required output load.
Turn on the power at the input.
2.
NOTE:
Make sure that the input voltage does not
exceed 75V.
Check for the proper output voltage.
3.
Vout = 28V, +/-3%.
If there is no output, temporarily disconnect the
load to make sure that the load is not set too high.

CSYS (330uF) that approximates typical system
rail capacitance. If system board already has ca-
pacitance of similar value CSYS can be removed.
