R203 is an extremely versatile Universal Input Energy power meter with a wide range of current measurement inputs. It can handle voltage-transduced currents, direct voltages, and Rogowski sensors with voltage output up to 333 mV. This instrument offers multiple insertion modes, including single-phase and three-phase 3/4-wire types, and is fully compatible with a range of communication protocols, including MQTT, HTTP POST, ModBUS RTU, ModBUS TCP-IP, and Peer-To-Peer. Available in four versions, it features a compact design with a depth of only 32 mm, enabling daisy-chain connection with automatic bypass protection (available in R203-2-L and R203-2-H versions). The power meter is capable of providing both voltage (0-10Vdc) and current (0/4-20mA) output signals. In addition, it offers advanced capabilities for measuring and recording harmonics up to the 55th order, with THD (total harmonic distortion) calculation, enabling a complete understanding of power quality
