Product overview


The STSW-STNRG011GUI graphical user interface is used to monitor and configure the mains parameters of the STNRG011/STNRG011A PFC/LLC controllers.

The GUI allows monitoring the controller key parameters in real-time (instantaneous power, PFC mode of operation, input voltage, VCC).

The STSW-STNRG011GUI also provides an easy and intuitive way of tuning the STNRG011/STNRG011A NVM parameters (each of them listed in the GUI).

To facilitate supply designers' activity, the STSW-STNRG011GUI embeds a comprehensive wizard to calibrate the PFC parameters. The calibration can be performed automatically (assuming AC source and DC load have GPIB remote capabilities) or semi-automatically (the GUI prompts the user for actions on the instruments).

In case an optional E²P is available in the design, the STSW-STNRG011GUI is able to decode Faults and Event history messages stored in the E²P memory. It can program also the E²P memory with a firmware patch if needed.

The STSW-STNRG011GUI requires an STEVAL-PCC020V2 interface board connected to an STNRG011/STNRG011A controller and a PC via USB.

The GUI is compatible with WindowsXP, Windows 7/8,10. No specific third-party software is needed.
