REGULATED MEDIUM VOLTAGE
OLTRONIX
POWER SUPPLIES
GENERAL
These 19" Rack - models are multiple voltage
high stability D. C. Power Supplies for uni-
v ersal use, when D. C. vo ltage of excellent
regulation is needed.
The y . are co nservatively constructed wi th
electron tube regulation. The amplifier
heaters in the major unit, 0-500 V, are fed
wi th regulated D . C. current providing lm-
proved regulation and low ripple.

Binding posts are provided on the front panel,
in addition a connector is located at the rear.
This connector also inc1udes terminals for
remote programming .
INPUT VOLTAGE
220 V 50-60 Hz may fluctuate bet wee n 200 V
and 240 V. Other input vo lta ge and frequency
on spe cial r eque s t.
SWITCHES
Separate switches are used for "LINE ON"
and "D . C. ON". LS120R and LS122R has one
"D.C. ON" switch for all D.C. output termi-
nals, LS124R has one swi tch for output A and
B and one for D and E.

REGULATION
The specifications above refer to:
a 10 0/'0 line voltage variation and
a no load to full load c hange.
METERS
One volt - and one amp-meter can be switched
for measurin g voltage and current from out -
put A, D and E.
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 %
of ma x. current. This feature is recognized
by the l et ter S af ter the model number, as in
LS 120 RS.
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. This is described In
detail in our manual.

REGULATED D. C. POWER SUPPLY
Type LS 122R
INPUT:
220V SO -60Hz (may fluctuate from 200 to 240V).
OUTPUT A
Voltage:
O -SOOV. COhtinuously variable
in two ranges O -2S0V and 2S0-
SOOV.
Current:
O
-SOOrnA.
Stability:
40mV for a 100/0 change In line
voltage.
Regulation: 2S0mV for a no load to full load
change
Ripple: lmV rms.
OUTPUT B Voltage: -lSOV fixed.
Curren t: O-lOOrnA.
Stability:
2SmV for a 100/0 change In line
voltage.
Regulation:
lSOmV for a no load to full load
change.
Ripple:
O, SmV rms.
OUTPUT C Voltage:
0- -lSOV, high impedance deri-
ved from B. Continuously vari-
able with a logarithmic potentio-
r
meter.
OUTPUT
E 6,3V
SOHz 6A.
OUTPUT F 6,3V
SOHz
6A.
The outputs A, B and C have a common zero and can be disconnected from the
terminals by a switch on the front panel (DC ON). All outputs can be obtained
a t the rear as well as on the front parel. Rear connector is Cannon MS 3102 A-
20-27S, suitable plug is MS 3106 B20-27P. The instrument is equipped with a
time delay realy delaying A about 4S sec. after the line is switched on.
FUSES
Primary:
4A.
Secondary:
A: SOOrnA
B: 100rnA
In addition a built in 3lSmA fuse for the V7-VIO screen grids is located elose
to the rear output terminal.

METERS
LS 122R has one voltmeter and one ammeter measuring voltage and current
in output A and D.
PROGRAMMING
Output A is remote programmable by connecting a resistor between the connec-
tors E and F in the rear contact. The programming constant is 200 ohm per Volt.
Very impo rtan t. When programing the LS 122R will provide O -500V in
one range. The voltage controI potentiometer is ganged
with a variable transformer and therefore the program-
ming range at full current is limited.
When the voltage range s witch on the front panel is III
O -250V position the voltage must not exceed 250V other-
wise the built in screen grid fuse will blow.
