DESCRIPTION :
The 1794 High Current Regulated D.C. Power Supply is completely solid and suitable
for bench operation or standard 19" rack operation. It is a well regulated constant
voltage / constant current supply which delivers 0-32V at 0-20Amps and can be
adjusted continuously throughout the output range. When the supply is used as a
constant voltage source the front panel VOLTAGE controls can be used to limit the
output voltage. When the unit is used as a constant current source, the front panel
CURRENT controls can be used to limit the output current. The unit will automatically
cross over from constant voltage to current mode and vice-versa if the output
current or voltage exceeds these limits.
Output voltage and current are continuously monitored on two front panel meters.
The load terminals and remote sense terminals are provided on the front panel.
Either the positive or negative output terminal may be grounded or the power supply
can be operated floating at upto a maximum of ±300VDC above ground.
OUTPUT ON/OFF SWITCH :
The output voltage and Current can be preset without connecting the power supply
to the load. With the OUTPUT ON/OFF switch in the OFF position, the maximum
voltage and current limits can be set. Pressing the OUTPUT ON switch connects
the output of the power supply to the load.
LIMIT SETTING :
The voltage and current limits can be set when the output is not connected to the
load. With the OUTPUT ON/OFF switch in the OFF position and the LIMIT switch
pressed, the voltage and current limits can be set with the front panel VOLTAGE
and CURRENT potentiometers.
REMOTE PROGRAMMING ( With External 5K Pot ) :
The output voltage of the unit can be programmed between 0 to 32V by means
of an external remote programming voltage resistor. An external resistance
programming selector link is provided on the rear panel for this purpose.
REMOTE SENSING :
The degradation in regulation which occurs at the load due to voltage drop in the
load leads can be eliminated by using the power supply in the remote sensing
mode operation. The remote sensing mode is selected by a push switch on the
front panel.
