25-50W, DC System Power Supplies, GPIB, Multiple Outputs

Clean and reliable power for general purpose applications

These supplies combine convenient benchtop capabilities with flexible system features in a compact, multi-output package. For bench-only applications, two models are available without I/O interfaces.

  • Address benchtop and ATE applications with up to three isolated dual-range outputs in a small package
  • Utilize GPIB and RS-232 interfaces with SCPI command set (drivers available)
  • Enhance signal integrity in test systems via low-noise outputs
  • Simplify cabling with built-in measurements
  • Streamline tasks with front panel control and basic programmable features
  • Ensure DUT safety with overvoltage protection
