Product description

The multifunctional measuring relay UG 9400 of the VARIMETER PRO series allows easy parameter setting, monitoring and diagnosis via a Modbus RTU interface. The measuring relay simultaneously monitors up to 9 different measured variables such as voltage, voltage asymmetry, current, cos phi, active, apparent and reactive power as well as frequency and phase sequence. The measurement in three-phase and single-phase networks is very easy and without much wiring effort.
