Product description

MEg44 Description
The MEg44 class S monitor measures three voltages and three currents of the DTS transformer
at LV level. It provides the functions of recording, electricity meter and analysis of
voltage quality, all performed simultaneously. Methods of measuring voltage quality meet
the requirements of EN 62586-2:2014.
In the recording function, the MEg44 monitor processes all measured quantities, evaluates
powers, energies and harmonics up to the 64th order. In the function of voltage quality analyser,
the monitor evaluates all parameters for measured three voltages and three currents, as
stipulated by the standard EN 61000-4-30:2015. When recording events, the monitor, aside
from recording the course of URMS1/2 and IRMS1/2, makes an oscillographic record of all measured
values of voltage and current.
The voltage measuring inputs are designed for direct voltage measurement at the LV level.
The current inputs are only designed for indirect measurement by means of instrument current
The monitor is equipped with three communication interfaces. The serial USB interface
is designed for local parametrisation devices and for downloading of measured data. The
Ethernet and RS485 interfaces are intended for connecting to local networks and for remote
downloading of data.
The MEg44 monitor is powered by 12 VDC from MEg101.4 or MEg101.5 uninterruptible power
supplies. It is possible to connect uninterruptible power supplies utilizing HBUS.
MEg44 monitor can be also connected to the MEg202.3 communication unit, which enables
remote transmission of parametrised and measured data via mobile network utilizing GSM /
The MEg44 unit is installed in a 108 × 90 × 63 mm polycarbonate, self-extinguishing box,
equipped for DIN rail mounting. Measuring category CAT IV / 300 V and safety class II qualified.
Information about SW.The MEg44 PQ monitor package includes a CD with user programs. Parametrization of measurements, reading of measured data.
