Multifunction network parameter meters
Relpol's RMM series multifunctional network parameter meters are modern measuring devices designed for comprehensive monitoring and analysis of electrical parameters of single- and three-phase networks in industrial, commercial, and power installations. These devices combine advanced True RMS measurements, intelligent energy recording, and power monitoring, which enables full control over the power grid and supports energy management systems (EMS).
Description of the Relpol RMM series
The Relpol RMM series devices are designed for universal monitoring of electrical parameters in single- and three-phase networks. Each model offers advanced True RMS measurements and features characteristic of professional network parameter meters used in EMS systems and industrial automation.
Examples of Relpol models
RMM-483-05 – network parameter meter with 0.5S accuracy, monitoring of active, apparent, and reactive energy and power, Modbus RTU communication. Up to 31 harmonic THD%.
RMM-483-10-U – model with direct measurement or CT/PT measurement capability, up to 31st harmonic THD%.
RMM-683-02 – high-precision meter with 0.2S accuracy class with additional I/O modules and optional Ethernet interface, up to 41th harmonic THD%.
