Multifunctional network parameter indicator DMM-5T-2

Application
DMM-5T-2 is a multifunctional, universal panel indicator 96x96 mm. It precisely monitors all important parameters of the electrical network - including analysis of the direction of energy flow and the distribution of voltage and current harmonics. It works in direct, semi-indirect and indirect measurement systems. It is equipped with a Modbus RTU communication interface, which enables remote reading of measured values.
