Features of Owon SPE6103 Power Supply

SCPI USB/Serial Commands

USB Interface is actually as USB to UART internal so when you connect it with PC, it will show up as COM port in the device manager. You need to use a serial terminal like Hercules Serial Terminal, select the right COM Port and 115200 Board rate and use the following command to interface

Each command should end with Life feed character (<LF>)

  • *IDN?
  • *RST
  • MEASure:VOLTage?
  • MEASure:CURRent?
  • MEASure:POWer?
  • OUTPut?
  • OUTPut {0|1|ON|OFF}
  • VOLTage <value>
  • VOLTage?
  • CURRent <value>
  • CURRent?
  • CURRent:LIMit <value>
  • VOLTage:LIMit <value>
