2231A-30-3
195W Triple Channel DC Power Supply
Supply 60V or 6A
When the application requires outputting more than 30V or 3A, the two 30V channels can be com-
bined to double the output level. Wire the two outputs in series to deliver up to 60V or wire them in
parallel to deliver up to 6A. For your convenience, the Model 2231A-30-3 display will read the total
output, either voltage or current, to eliminate confusion. Also, the supply controls both outputs to
deliver the required voltage or current. There’s no need to set up each channel individually; the sup-
ply manages the channels for you, so combining channels is uncomplicated.
Wire the two 30V channels in series or parallel to double the output voltage to 60V or the
supplied current to 6A. The Model 2231A-30-3 has series and parallel modes that manage the
channels and display the total output. This display shows the supply’s parallel mode, including
the output voltage and the total current from the channels wired in parallel.
Easily Test, Monitor, and Protect Your Circuits
• Adjust the outputs with the rotary knob or enter the output values precisely using the keypad with
setting resolution of 10mV or 1mA.
• See the voltage and current readings on all channels at all times; the Model 2231A-30-3’s display
shows the readings from all three outputs simultaneously.
• Protect your DUT with an overvoltage protection setting for each output.
• Set timers to turn off an output after a programmed time to prevent excess stress on a circuit
under development.
• Store and recall instrument setups for frequently used tests to begin testing quickly. You can store
up to 30 unique test setups.

Control the Supply and Upload Data to a PC
Use the optional Model 2231A-001 USB Adapter to control the Model 2231A-30-1 via a PC’s USB inter-
face, then transfer readings from the outputs to combine with other test data for a more thorough
analysis of DUT performance. The 2231A-001 USB Adapter provides the flexibility to use the supply
under either manual or automated control.
