UMD 710MVU – Metrology for busbar in CAT IV environments for medium voltage applications


The UMD 710MVU is a compact high-end power quality measuring device for CAT IV environments for DIN rail mounting. The UMD 710MVU is equipped with an extra-low voltage input for direct connection of voltage sensors with an output signal of 3.25 V / √3. It measures 3-phase current and voltage with up to 3 tariffs in 4-quadrant operation in class 0.05 and thus the work in class 0.2s, as well as all usual mains quantities, e.g. harmonics up to the 128th harmonic and optionally the super harmonics from 2 kHz to 9 kHz. The unit maps the power quality according to EN 50160, EN 61000-2-2, EN 61000-2-4 and EN 61000-2-12 and measures according to EN 61000-4-30 in class A.

It has a large 512 MB memory. The unit can be accessed via the Ethernet interface and live measured values can be viewed via the associated web server using a web browser. This also allows internet protocols such as NTP to be read in and PLC systems and building management systems to be easily connected. 4 digital inputs/outputs and a serial RS485 interface are integrated.


The unit is used in all CAT IV environments. A suitable CAT IV power supply unit can be found in our accessories.
