This interface enables RS232 communication with analog programmable power supplies. The interface is available as a factory built-in option or as an external PSC module. This page covers both versions. 

The RS232 interface sets both output voltage and current and is able to read voltage, current and status. The interface also controls Remote/Local, Remote Shut Down and more. Up to 15 PSCs can be connected to only one RS232 port. The analog voltages can be calibrated by software. The calibration settings can be saved in non-volatile memory and recalled at power on.


  • Programming and monitoring of voltage and current
  • Up to 15 PSCs on one BUS
  • Software calibration
  • Isolated digital user in- and outputs
  • Factory installed or as external module


  • Monitoring status outputs: ACF, DCF, CC-mode, Over Temp, PSOL etc.
  • Two isolated user inputs and outputs (external modules only)
  • Software calibration for off set and full scale


  • Programming and monitoring resolution: 14 bit
  • Linearity error: +/- 2 LSB (prg.), +/- 1 LSB (mon.)
