2231A-30-3

195W Triple Channel DC Power Supply

• Get three isolated, independent,

and adjustable outputs in one

instrument

• Output a total of 195W of power

with two 30V@3A outputs and

one 5V@3A output

• Set voltage outputs with 0.06%

basic accuracy and current

outputs with 0.2% basic

accuracy

• Output DC power with less than

5mVp-p noise

• Display voltage and current

measurements continuously

from all three outputs

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.

Common 3

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.
