Universal energy meter
Universal meters from Janitza are available in both panel mounted and DIN rail versions 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
Contemporary measurement technology, coupled with high sample rates, ensures precise measurement of the power consumption of electronic loads like frequency converters, LED lighting, and charging stations. 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 TCP over IP, Profibus, Profinet, Bacnet IP, M-Bus, making it possible to integrate into almost all overhead systems.

Temporary or permanent measurement?
For a company, insight into the electrical installation is a must. This can be achieved through measurements: temporary or permanent. Which one should you choose? Is a temporary measurement a logical choice? The answer is no. A temporary measurement is essentially a snapshot of the installation—just a moment in time.
From snapshot to continuous insight
Production processes, weather conditions, and seasons influence power consumption, and faults occur without warning. A permanent measurement is like a film that captures everything needed for analysis and reporting.
