Personal Greeting

The 9140 Series triple output multi-range DC power supplies combine industry-leading power density and performance with an extensive set of features in a compact 2U form factor. Three isolated output channels each produce 100 W of clean power with low ripple and noise characteristics. Combine channels for up to 300 W total output power.

Powerful list mode programming enables users to set up and execute complex test sequences directly from the front panel. Multiple outputs, USB data logging, and comprehensive protection features make these power supplies suitable for a wide range of benchtop or test system applications.

  • Three independent, floating output channels for up to 100 W per channel or 300 W total
  • High power density, compact 2U half-rack form factor
  • Multi-ranging operation
  • Low output ripple and noise down to 1 mVrms
  • Combine outputs to increase voltage up to 180 V or 24 A (depending on model)
  • Advanced and easy to use list mode programming
  • Channel coupling, tracking, configurable delays
  • Direct data logging to USB flash drive
  • Thermostatically-controlled fans for quiet operation
