DC Power Supply Rohde & Schwarz HMC8042-G, 2 channel, 0V to 32V/5A, 100W, resolution 1mV/0.1mA, tracking, EasyArb, electronic fuse, FuseLink, USB stick connect, Ethernet/USB


  • Realtime voltage, current and power values
  • High setting and readback resolution
  • Low residual ripple due to linear postregulation
  • High energy efficiency, low heat dissipation and quiet fans
  • Convenient parallel and serial operation via V/I tracking
  • Overvoltage and overpower protection (OVP, OPP) for all outputs
  • FuseLink: individual channel combination of electronic fuses
  • EasyArb function for user-definable V/I curves
  • EasyRamp for simulating a start-up curve
  • Sequencing (sequenced start of channels)
  • Energy meter (measurement of energy output)
  • Data logging to USB flash drive in CSV format
