UMD 710A – Measurement technology for the top-hat rail

UMD 710A

The UMD 710A is a compact high-end power quality meter for DIN rail mounting. It measures 4-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 common mains quantities, e.g. harmonics up to the 128th harmonic. With the 5th connection, residual currents can be measured continuously. The unit maps the power quality according to EN 50160, EN 61000-2-2, EN 61000-2-4, EN 61000-2-12 and measures in class A according to EN 61000-4-30. 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 means that Internet protocols such as NTP can also be read in and PLC systems and building management systems can be easily connected. Digital inputs/outputs and a serial RS485 interface are integrated. With the firmware module GO, oscilloscope functions for current and voltage are activated and trigger signals for limit value events are set. With the software module PQ S or PQ A, the voltage quality is continuously recorded and evaluated.


The unit is used for continuous monitoring of the voltage quality in data centres, buildings or at energy suppliers. Furthermore, the UMD 710A is used with a corresponding residual current transformer for the detection of residual currents/differential currents.
