UMC 26 – Reactive power controller

UMC 26

The UMC 26 is a powerful front panel meter and a 1/3-phase reactive power controller and replaces all analogue meters and individual controllers. It measures 3-phase current and voltage in 4-quadrant operation in class 0.2 and thus the work in class 0.5 as well as all usual network variables, e.g. harmonics up to the 50th harmonic.

As a reactive power controller, it regulates compliance with contractually agreed cos phi ratios via disconnection/connection of capacitor stages. It can be connected via current transformers with N/5 A and N/1 A. It has a bright, large and easy-to-read digital display. It is conveniently operated via 4 function keys. It is used in 400 V networks as well as in 690 V networks.

Versions with 7, 9, 16 and 18 outputs are available as relay outputs. These can also be used as alarm outputs. It 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 connection with Modbus are integrated. The unit is parameterised and visualised with the Envis software.
