UMG 103-CBM-CH Messgerät für DIN

The UMG 103 is a universal measuring device for top-hat rail mounting in low-voltage distribution systems and is used to measure and check electrical parameters in power distribution systems. It measures harmonics up to the 25th harmonic. In addition to a large number of energy values and electrical measured values, it offers a variety of additional functions, such as the measurement of harmonics, storage of minimum and maximum values, operating hours counter and bimetal function.

Measurement data recording:

- If all profiles are activated, 400000 measured values can be saved

- Corresponds to a time range of 144 days

- Measurement data with precise time stamp

- Storage of minimum, maximum and working values

Communication:

- RS485 with line earth and 3-pin plug (A, B, GND)

- Galvanic isolation including DC/DC converter

- Clear and intuitive setting directly on the device

Technical data:

- Auxiliary voltage up to 277 V

- Measuring voltage up to 480 V

- Active energy class 0.5S (DIN EN62053-22:2003) for .../5 A current transformers

Voltage and current measurement:

- Continuous scanning of the voltage and current measurement inputs

- Overvoltage category 300 V CATIII

- Measurement of positive, negative and zero sequence system

- Knowledge of interfering factors that can damage motors, for example

- Measurement of distortion reactive power

- Detection of unnecessary current loads, e.g. for distribution boards, transformers and consumers

Installation:

- Mounting on a 35 mm top-hat rail

- System requirements GridVis 7.1.6
