The Model 2231A-30-3 Triple Channel DC Power Supply can output a total of 195W of power, provid-
ing the power levels needed to energize a wide range of circuits and devices for benchtop work. Two
channels can supply up to 30V at 3A each; the third channel can provide up to 5V at 3A. The Model
2231A-30-1 does not compromise on performance or convenience features, offering the versatility
and ease of use you need, so it can be the only DC power supply on your bench.
• Double output levels by
connecting the two 30V channels
in series or parallel
• Store frequently used
configurations in any of 30 setup
memory locations
Quality DC Power
The Model 2231A-30-3 is a linear-based design with less than 5mVp-p noise per output. Voltage and
current settings have basic accuracies of 0.06% and 0.2% respectively. The load voltage and load cur-
rent readback results provide the same levels of accuracy, so you can be confident you are sourcing
accurate, low noise voltages and currents to your device-under-test (DUT).
• Turn off any output after a
predetermined test time with
each channel’s output timer
• Control the supply from a PC
with an optional USB adapter
Three Fully Independent Outputs
Each output of the Model 2231A-30-3 is fully programmable and can be turned on and off inde-
pendently from the other chanqnels; it essentially provides three power supplies in one instrument.
You can power up both the analog circuitry and the digital circuitry of a printed circuit board or a
complete device, all with the same instrument.
All Outputs Are Isolated from Each Other and from Ground
APPLICATIONS
Each output can power a circuit on a different ground reference. The low connection on each output
is not connected to any of the other outputs. That means one supply can test three separate circuits
on three different ground references or can power circuits that are transformer or optically isolated
from each other. Furthermore, all outputs are not referenced to ground, so the Model 2231A-30-3 can
power both floating circuits and grounded circuits.

Power Bipolar Circuits
Because the Model 2231A-30-3’s outputs are
isolated, one output can be turned effectively

V3
into a negative source by connecting its high
terminal to the common reference point
of a bipolar circuit. A second output can
connect its low terminal to the same com-
mon reference point. The result is a positive
output and a negative output. If the two 30V
channels are used in this configuration, both
outputs can be changed at the same time by
using the Model 2231A-30-3’s tracking func-
tion. That allows varying both channels at
the same time while keeping their outputs at
identical magnitudes.

The Model 2231A-30-3 has three fully indepen-
dent, programmable outputs that are electrically
isolated from each other. This allows them to
power circuits that are on different grounds, such
as optically isolated circuits.
