features:
• No derating. All
outputs
may be operated simul·

capacity
for
a
maximum
of 140W.
•
Outputs
are floatin'Q
with
respect
to
each
other
and chassis except for an _internal connection
between one negative terminal and one
positive
terminal
of
the
20
volt sources. The

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-

• Separately adjustable overvoltage crowbars on
each output. Overvoltage crowbars on 0·20V out·
