PS48401 - PXI Programmable Power Supply
The PS48401 is a Programmable DC Power supply in a 2-slot PXI / cPCI form factor. Featuring a fully isolated output capable of providing 0-48VDC / 2A / 40W. It offers a programmable current limit and the ability to measure the output voltage and current under software or trigger control.

Special functions:
  • Measure output voltage or current, software controlled.
  • Measure output voltage or current, external trigger controlled.
  • Update output voltage and current limit, external trigger controlled.
  • Sequence above functions and store measured values into on-board memory
