The R203 three-phase power meter accepts current measurement inputs for CT with current / voltage output, VT and Rogowski sensors (with voltage output up to 333 mV), with single-phase, three-phase 3/4-wire insertion types and with the support of ModBUS RTU, ModBUS TCP-IP, Peer-To-Peer protocols. Like most of the "space-saving" R series products, R203 has 2 Ethernet ports that can also be used for daisy chain series connections with automatic bypass protection.

The power meter provides an output signal in voltage (0..10 Vdc), current (0/4..20 mA). R203 also offers measurement and recording of voltage/current harmonics up to 55th order with THD (total harmonic distortion) calculation. The instrument also operates like Web Server and datalogger for reading the main parameters and downloading from data and events.
