R203-E

3-PHASE ENERGY POWER METER

WITH 2 ETHERNET PORTS AND ETHERNET/IP PROTOCOL

The three-phase energy power meter R203-E accepts current measurement inputs for CTs with current/voltage output, TVs and Rogowski sensors (with voltage output up to 333 mV), with single-phase, three-phase 3/4-wire, Aron and Ethernet/IP protocol support. Thanks to the Ethernet interface, a daisy chain connection to the next Ethernet device can be realized, avoiding expensive industrial switches and simplifying wiring. The R203-E returns single-phase and three-phase values of the main electrical quantities: voltage, current, active, reactive, apparent power, frequency, period, power factor and harmonics. The configurable analog output in voltage or current al-lows the analyzer to also be used as a measurement converter. The R203-E also offers measurement and recording of harmonics in voltage/current up to 55th order with THD (total harmonic distortion) calculation.

Highlights

• Universal input in voltage, current, TA with A/mV output, TV, Rogowski sensors
• Optimized display on Surprise Smart Display
• Full scale input: 600 Vac (voltage), 5A (TA), TA with voltage output, Rogowski (250 mV)
• Output: mA/V
• Accuracy Class: 0.2% for voltage/current; 0.5% for power
• Operating temperature: -25..+75°C
• Ethernet Daisy Chain connection
• Configuration: EDS, Web Server
