PQM-EM current measuring extension module for PQM analyzers

In case of branching from busbars there is a need for measuring currents on all the branches. The PQM-x3x device can be completed by using the PQM-EM extension module, that allows 4x or 6x 3-phase additional current measurement channels beyond the original capabilities of the base device. Even 5 modules can be connected via an RS-485 bus, providing excellent flexibility. The collected data are available in the database under the ID and GNSS location of the base PQM.
