Applications

Universal measuring devices of the UMG 103 product family are mainly designed for use in low voltage distribution systems.

The UMG 103 is a measuring instrument with an effective energy class of 0.5S.

In addition to a large quantity of electrical measurement values, the UMG 103 offers a multitude of additional functions such as the measurement of harmonics, the storage of minimum and maximum values, operating hour meter, bi-metallic strip function and password protection. The interface and field bus capabilities (Modbus) enable the communication of measurement data and incorporation into a comprehensive energy management system.
