DESGRIPTION
The
13028Power
Supplyis
a
high
performance
triple
output
DC
power
supply
for
industrial
andlaboratory
use.
Performance
and
economy
have
successfully
been
combined
to
provide
acompact,
fully
solid
state
in-
stru
ment.
The
two
main
outputs
arecontinuously
variable
from
Oto
32V
and
can
supply2A
max
each.They
can
beoperated
in
constant
voltage
or
con-
stant

modes.
Automatic

is
achieved
by
