The UMD 710EVU is a compact high-end power quality meter for CAT IV environments for DIN rail mounting. 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 common mains quantities, e.g. harmonics up to the 128th harmonic. 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. 4 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 firmware module PQ A, the voltage quality is continuously recorded and evaluated.
The unit is used in all CAT IV environments. A suitable CAT IV power supply unit can be found in our accessories.
