Product information "Helvatron Multifunctional network analyser with TCP/IP & Modbus TCP UMD 97EL"

The UMD 97EL is a powerful front panel meter (96x96mm) and replaces all analogue measuring devices. It measures 3-phase current and voltage in 6-quadrant operation in class 0.2 and thus the energy class 0.5s as well as all common mains variables, e.g. harmonics up to the 50th harmonic. It can be connected via current transformers with N/5A and N/1A. With the PQ S module, the universal measuring device maps the power quality in accordance with EN 50160, EN 61000-4-30, EN 61557-12, EN 62053-22. The UMD 97EL is conveniently operated via 5 function keys. A PT100 sensor is integrated internally. It can be used in both 400V and IT networks. It has a large 512 MB memory. The device can be accessed via the Ethernet interface and the mini-USB port on the front. The UMD 97EL has one digital input and 2 digital outputs. The measuring device can be extended with the PQ S and GO firmware modules for analysing the network.
