The S203RC-D is a complete three-phase network analyzer with high visibility display for exclusive use with Rogowski sensors. S203RC-D is suitable for voltage ranges up to 600 Vac (50 Hz or 60 Hz) and maximum currents up to 1.000 A connected to the inputs. The instrument is able to supply all the following electrical quantities: Vrms, Irms, Watt, VAR, VA Frequency, Active Energy Cosphs. For the variables listed above (except frequency) both phase values and the total three-phase value are available. All values can be acquired through serial communication either in floating point or normalized format (except frequency and Active Energy).
