features:
• No
derating.
All
outputs may
be
operated simul·
taneously at
full
capacity for a maximum of 140W.
• Outputs are floatin'Q
with
respect to each other
and chassis except for an
_
i
nternal
connection
between
one negative terminal and one
positive
terminal of the
20 volt
sources.
The
two 20 volt
sources may
be
operated in series
to
provide 0-40
VDC, 0·2.5A
in any
polarity
with
respect
to chassis
or left floating. The
0·1
5V
source may
be
operated
in
any
polarity
with
respect
to chassis
or
left
floating
.
• Independent
adjustment of each output voltage
utilizing 10·turn potentiometers with
.05%
reso-
lution
.
• Separate current
limiting
adjustment for
each
output.
• Separately adjustable overvoltage
crowbars
on
each output. Overvoltage

Outputs may be
shorted into each other in any
polarity without damage.
