DESCRIPTION
The LPS-

1/152 DC Tracking
Power Supplies
each
pro-
vide
three regulated
voltage sources,
covering
the 0 to
6
V,
0
to 25V
and
0 to -25V ranges.
The
+
25V and
-25V range
sources
can also be used
in a voltage tracking
mode. These
power
supplies
are equipped
with a built-in
voltmeter
and
ammeter
so that the output
conditions for each
section
of the
supply can
be
monitored
individually.

FEATURES
1. The
+25V and
—25V
sources
can be
used
in a
voltage
ratio tracking
mode.
2. A
source
of
50V
may
be obtained by
connecting
the
load
across the
+25V and
-25V terminals.
3.
Voltage and
current
settings
are made
via
front panel con-
trols
and
can be
monitored on the
built-in
voltmeter
and
ammeter.
