2230G-30-3, 2230G-30-6, 2230G-60-3
High Power, 3-Channel Programmable Power Supplies
Deliver accurate voltages
to the load
The setting and measurement basic voltage
accuracy of each channel is 0.03%; and the
setting and measurement resolution is 1 mV.
Thus, the user can be confident that the
programmed output is accurately applied to
the output terminals. In addition, using the
remote sense leads for each channel ensures
that the programmed voltage is applied to the
load; the remote sense leads compensate for
and overcome the voltage drops due to the
resistances in the test leads.
Convenience features
simplify manual operation
The Series 2230G high power supplies have
valuable features that enable easy use for
manual testing.
• When the outputs are off, the display
shows the previously programmed voltage
and current settings. This ensures that an incorrect
output is not applied to a DUT when the outputs are
turned on.
• The displays for all three channels are shown so each
channel’s output is always visible to give the user
immediate feedback on the status of the DUT.
• Output voltages can be controlled by the rotary knob
or with the numeric keypad to test DUT response to
large changes or small changes.
• Save the setup parameters for tests that are
performed repetitively in one of 36 memory locations
and save time reproducing each test. Front panel
Save and Recall buttons make saving and recalling
a setup an easy operation to perform.
Protection for your DUT in both
manual and automated operation
The Series 2230G supplies have a set of features
designed to protect the DUT. Each channel has a
maximum voltage setting that prevents the output voltage
from being accidentally adjusted above a programmed
limit. Independent outputs allow a different limit to be
programmed for each output channel. Also, a user-
definable password allows the front panel to be locked
to prevent any changes in parameters during testing.
For unattended testing, programmable timers on each
channel can turn the outputs off after a test has been
completed. This ensures that a DUT that is not yet fully
temperature controlled does not overheat due to the
application of continuous power.
