Primary/Secondary Front Panel Display
The current value read from the front panel of the primary unit is the aggregate of the values of the
primary and the secondary units. The secondary units return their individual current values.
The following example illustrates the front panel displays during primary/secondary operation. Three
units are connected in a primary/secondary configuration. The units are operating in voltage priority
mode.
This is the 20 kW primary unit.
"P" indicates theprimary unit. The current
displayed (30 A) is the total output current of all
paralleled units. This unit is only contributing 10 A
to the total.
This is the 20 kW secondary unit.
"S" indicates a secondary unit. The current
displayed (10 A) is the current that this unit is
contributing to the total.

Primary/Secondary Programming Considerations
Program the output voltage and current settings of the primary unit the same as you would an
individual unit. The current limits will reflect the total capacity of the paralleled units. Refer to
and
for details. The secondary units are locked; you cannot
program the settings of the secondary units.
Set the positive current limit high to allow extra headroom for the up-programming transient
dynamics. Transient dynamics are mainly a result of DUT capacitance charging currents. Note that the
