The PSC is an RS232 or IEEE488 interface, designed for an analog programmable power supply. The PSC sets output voltage and current and reads the voltage, current and status. The PSC also controls Remote/Local, Remote Shut Down etc. Up to 15 PSC’s can be connected to only one RS232 port or IEEE488 bus. The analog voltages can be calibrated by software. The calibration settings can be saved in non volatile memory and recalled at power on.
