Large measurement data memory 
for even more data security 
Qualified statements on energy consumption and 
power quality cannot be achieved with measurements that are restricted just to the point of common coupling (PCC). If one wishes to discover fault 
sources or energy wasters, it is necessary to acquire data at several points across the grid, i.e. the 
resolution of the measurement is critical. But this is 
often a question of space and cost. 
The new UMG 103-CBM is the ideal solution for 
this task. The extremely compact and affordable 
universal measurement device requires a width of 
just 71.5 mm on the mounting rail and so fits conveniently into any installation distributor. Along 
with a large number of energy values and electrical 
measured values it offers a multitude of additional 
functions such as the measurement of harmonics, 
saving of minimum and maximum values, operating hours counter and bi-metallic strip function. It 
can be operated both as a Slave to a higher-level 
device, such as the UMG 604E for example, or directly connected with a PC. 
A wide variety of application areas is opened due 
to the clock, battery and memory. It is suitable for 
the measurement and checking of electrical characteristics, the energy consumption and for monitoring the power quality, e.g. harmonics. Suitable 
applications include energy distribution systems, 
cost centre accounting and threshold value monitoring and it can also be used as a measured value 
transducer for building management systems or 
PLCs
