is
ahigh

DC
power
supply
for
industrial
andlaboratory
use.
Performance
with
economy
have
successfully
been
combined
to
provide
acompact,

instrument.
The
output
is
continuously
variable

and
can
supply

and
can
beadjusted
continuously
throughout
the
output
range.
The
front

can
be
used
to
establish

When
the

is
used
as

source
the

can
be
used
to
limit
the

When

can
beused
tolimit

and
vice-versa,
if
the

orvoltage
exceeds
these
preset

are
continuously
