New Multifunction Network Parameter Meters by Relpol
Relpol introduces a new range of modern multifunctional RMM meters, designed for comprehensive monitoring of electrical network parameters in single- and three-phase installations.
Devices in this line combine advanced True RMS measurements with energy recording and maximum/minimum power monitoring functions. Each model is equipped with a clear 4-line LCD display with a bar graph and Modbus RTU communication via RS-485 (and, in selected versions, Ethernet). The meters comply with EMC Directive 2014/30/EU and PN-EN standards, ensuring high accuracy and immunity to interference. The new RMM series is an ideal solution for energy management systems (EMS), industrial automation, and power infrastructure.
