The UMG 103-CBM is a three-phase universal energy meter designed to perform accurate measurements in both TN and TT networks. The meter is equipped with a clock, a battery, and 4 MB of memory for storing measurement data, making it a reliable and sustainable solution for energy monitoring.
The energy meter can measure harmonics up to the 25th order and has four voltage measurement inputs for three-phase four-wire systems up to 277 V and three-phase three-wire systems up to 480 V. Additionally, there are three current measurement inputs for current transformers with an adjustable nominal current of 5/1A.
The measured current ranges from 0.005 to 6 A. For easy integration with other systems, the energy meter features an RS485 interface that supports Modbus RTU/slave communication. This allows for remote reading and management of the meter, making it an ideal choice for industrial and utility applications.
