3-Year Warranty 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- Double output levels by ing the power levels needed to energize a wide range of circuits and devices for benchtop work. Two connecting the two 30V channels channels can supply up to 30V at 3A each the third channel can provide up to 5V at 3A. The Model in series or parallel 2231A-30-1 does not compromise on performance or convenience features, offering the versatility Store frequently used and ease of use you need, so it can be the only DC power supply on your bench. configurations in any of 30 setup Quality DC Power memory locations The Model 2231A-30-3 is a linear-based design with less than 5mVp-p noise per output. Voltage and Turn off any output after a current settings have basic accuracies of 0.06% and 0.2% respectively. The load voltage and load cur- predetermined test time with rent readback results provide the same levels of accuracy, so you can be confident you are sourcing each channels output timer accurate, low noise voltages and currents to your device-under-test (DUT). Control the supply from a PC Three Fully Independent Outputs with an optional USB adapter 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 Engineering and science is not connected to any of the other outputs. That means one supply can test three separate circuits student labs 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 Service work power both floating circuits and grounded circuits. Electronic design Power Bipolar Circuits Because the Model 2231A-30-3s outputs are isolated, one output can be turned effectively V V V 1 2 3 into a negative source by connecting its high terminal to the common reference point of a bipolar circuit.

Wire the two outputs in series to deliver up to 60V or wire them in 2231A-30-3 parallel to deliver up to 6A. For your convenience, the Model 2231A-30-3 display will read the total Triple Channel DC output, either voltage or current, to eliminate confusion. Also, the supply controls both outputs to Power Supply deliver the required voltage or current. Theres no need to set up each channel individually the sup- ply manages the channels for you, so combining channels is uncomplicated.
