The UMD 96 is a powerful front panel meter* and replaces all analogue meters. It measures 3-phase current and voltage in 4-quadrant operation in class 0.2 and thus the work in class 0.5s as well as all common mains quantities, e.g. harmonics up to the 50th harmonic. It can be measured via current transformers with N/5 A and N/1 A as well as via Rogowski coils (333 mV). It has an illuminated, large and easy-to-read digital display. It is conveniently operated via 4 function keys. A PT100 sensor is integrated internally. It is used in 400 V networks as well as in 690 V networks. Optionally, the UMD 96 can also be equipped with an Ethernet interface and a web server. This makes it easy to connect PLC systems and building management systems. Digital inputs/outputs and a serial RS485 interface with Modbus are available. The unit is parameterised and visualised with the ENVIS software.
* also suitable for top-hat rail mounting with adapter
The device is used for consumption measurement in LV and sub-distribution boards.
