REGULATION
The
specifications
above
refer
to:
a
10

line
voltage
variation
and
a
no
load
to

c
hange.
METERS
One
volt

and
one
amp-meter
can
be
switched
for
measurin

and
current
from

ADJUSTABLE
PROTECTION
The
different
outputs
are
ordinarily
fused
with
thermal
fuses,
but
on
special
order
the
output
A
can
be
provided
with
a
transistori

This
feature
is
recognized
by
the

REMOTE
PROGRAMMING
The
output
A
on
LS
120
R
and
LS
122
R
can
be
controlled
externallyby
connecting
a
resistor
bet
ween
the
connectors
E
and
F
in
the
rear
contact.
The
programming
constant
is
200
ohms
per
volt,
and
it
is
possible
to
cover
the
whole
voltage
range
w
ithout
switching
or
other
adjustment,
if
a
reduction
of
the
output
curr-
ent
is
permissible.
