Keithley Model 2231A-30-3 Power Supply

Keithley Instruments Model 2231A-30-3 Triple Channel DC Power Supply can output a total of 195W of power, providing 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.

Each is fully programmable and can be turned on and off independently from the other channels, essentially providing three power supplies in one instrument. 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 and all outputs are not referenced to ground, so the Keithley  Model 2231A-30-3 can power both floating circuits and grounded circuits.

Features

  • 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
  • Double output levels by connecting the two 30V channels in series or parallel
  • Store frequently used configurations in any of 30 setup memory locations
  • Turn off any output after a predetermined test time with each channels output timer
  • Control the supply from a PC with an optional USB adapter
