Frequency meter power meter R204-2-L-U

multimeterenergy meterwith power quality and harmonic analyzer

The R204 OPC UA three-phase power meter, UL certified, is designed to accept current measurement inputs via current transformers (CTs) with current or voltage output, voltage transformers (VTs), and Rogowski sensors with voltage output up to 333 mV. It supports various insertion types, including single-phase, three-phase 3/4-wire, and Aron, and is compatible with the OPC UA Server protocol (switchable to Modbus, Profinet, or Ethernet/IP thanks to SENECA FLEX technology). The Ethernet interface enables daisy chaining to the next Ethernet device, avoiding the use of expensive industrial switches and simplifying wiring. The R204 OPC UA returns single-phase and three-phase values of the main electrical quantities: voltage, current, active power, reactive power, apparent power, frequency, period, and power factor. R204 OPC UA also offers measurement and recording of harmonics in voltage and current up to 55th order with THD (total harmonic distortion) calculation. This versatile solution is ideal for monitoring and analyzing the performance of electrical networks, as well as converting measurement signals for industrial control and automation systems.
