SECTION I
GENERAL INFORMATION
1-1 DESCRIPTION
1-2 This power supply is completely tran-
sistorized and suitable for either bench or
relay rack operation. It is a compact, well-regu-
lated. Constant Voltage/ Constant Current supply
that will furnish full rated output voltage at the
maximum
rated output current or can be conUnuous-
1 y adjusted throughout the output range. The front
panel
CURRENT controls can be used to establish
the output current limit (overload or shon circuit)
when
the supply is used as a constant voltage
source and the VOLTAGE control can be uaed to
establish the voltage limit (ce1Ung) when the sup-
ply is used as a constant current source. The
supply will automatically crossover from constant
voltage to constant current operation and Vice
versa if the output CUITant or voltage exceeds these
preset limits.
1-3 The power supply has both front and rear
terminals. Either the positive or negative output
terminal may
be qrounded or the power supply can
be operated floating at up to a maximum of 300
volts off ground.
1-4 A single meter is used to measure either out-
put voltage or output current in one of two ranges.
The
voltage or current ranges are selected by a
METER switch on the front panel.
1-S Barrier strip terminals located at the rear of
the
unit allow ease in adapting to the many oper-
ational capabiUU~s of the power supply. A brief
description of these capabilities is given below:
a. Remote Programming
The power
supply may be programmed
from a remote location by means of an external
voltage source or resistance.
b. Remote Sensing
The degradation in regulation which
would
occur at the load because of the voltage
drop
in the load leads can be reduced by using the
power
supply in the ·remote sensing mode of oper-
ation.
1-1
c. Series and Auto-Series Operation
Power
supplies may be used in series
when a higher output voltage is required in the
voltage mode of operation or when greater voltage
compliance is required in the constant current
mode
of operation. Auto-Series operation permits
one knob control of the total output voltage from a
"master" supply.
d. Parallel and Auto-Parallel Qperation
The power
supply may be operated in
parallel with a similar unit when greater output
current capability is required. Auto-Parallel op-
eration permits one knob control of the total out-
put current from a "master" supply.
e. Auto-Track1n9
The power
supply may be used as a
"master" supply. havin9 control over one (or
more) "slave" supplies that furnish various
voltages for a system.

1-9 Options are factory modifications of a
standard instrument that are requested by the
customer. The follOWirlCJ options are available
for the instrument covered by this manual.

Description
SO Hz Regulator Realignment:
Standard instruments will operate
saUsfactorily at both 60 and 50 Hz
without adjustment. However Op-
tion 05 factory reall9nment results
in more efficient operation at 50 Hz,
and is recommended for all applica-
tions when continuous operation from
a SO Hz ae input is intended .
