Universal meters - Universal energy meter

Universal meters from Janitza are available as panel mounting and DIN rail version and can be equipped with various communication protocols. Depending on the type, the meters are provided with sufficient memory to store measurement profiles.

Determine the right load

The modern measuring technology and the high sample rate also accurately measure the power of electronic loads such as frequency converters, LED lighting and charging facilities. This way there are no 'holes' in the consumption measurement and the correct load is determined. The UMG 96RM series is suitable for panel mounting while the UMG 103-CBM is suitable for DIN rail mounting.

Interfacing

Depending on the model, the Janitza Universal Meters are delivered with different bus protocols. Modbus RTU over RS485, Modbus over TCP over IP, Profibus, Profinet, Bacnet IP, M-Bus, making it possible to integrate into almost all overhead systems.
