Relpol’s New Multifunction Power Network Parameter Meters
Relpol’s New Multifunction Power Network Parameter Meters
Relpol introduces a modern series of RMM multifunction meters to its product range, designed for comprehensive monitoring of electrical network parameters in single-phase and three-phase installations.
Devices in this line combine advanced True RMS measurements with energy logging, as well as maximum and minimum power monitoring. Each model features a clear 4-line LCD with a bar graph and Modbus RTU communication via RS-485 (selected versions also offer Ethernet). The meters meet the requirements of the EMC Directive 2014/30/EU and relevant PN-EN standards, ensuring high accuracy and strong immunity to interference. The new RMM line is an ideal solution for energy management systems (EMS), industrial automation, and power infrastructure applications.
