REGULATION
The

above
refer
to:
a

line
voltage
variation
and
a
no
load
to

c
hange.
METERS
One
volt
-
and
one
amp-meter
can
be
switched
for
measurin
g
voltage
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
zed
protecting
circuit
adjustable
w
ithin
10-100
%

current.
This
feature
is
recognized
by

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.
