PQ Plus UMD 710A Digital rail-mount meter

The UMD 710A is a compact high-end power quality measuring device for mounting on the DIN rail. 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 0.2 s, as well as all usual line sizes, e.g. harmonics up to 128. Harmonious. With the 5. Connection fault currents can be measured continuously. The device represents the power quality according to EN 50160, EN 61000-2-2, EN 61000-2-4, EN 61000-2-12 and is certified according to class A. It has a large 512 MB memory. The device can be accessed via the Ethernet interface and live measured values can be viewed via the web browser via the corresponding web server. This means that Internet protocols such as NTP can also be read in and PLC systems and building control systems can be easily connected. Digital inputs/outputs and a serial RS485 interface are integrated. With the GO firmware module, oscilloscope functions for current and voltage are activated and trigger signals for limit value events are set. The PQ A software module continuously records and evaluates the voltage quality.
