Product Description:


The UMG 103-CBM is a universal three-phase energy meter designed for precise monitoring in both TN and TT network configurations. It comes equipped with an internal clock, battery backup, and 4 MB of memory for reliable data logging, making it a durable and efficient solution for ongoing energy management.

This meter supports harmonic analysis up to the 25th order and includes four voltage inputs—suitable for three-phase, four-wire systems up to 277 V and three-phase, three-wire systems up to 480 V. It also features three current inputs compatible with current transformers (CTs), offering configurable nominal values of 5 A or 1 A.

With a current measurement range from 0.005 to 6 A, the UMG 103-CBM is well-suited for detailed monitoring. The built-in RS485 interface with Modbus RTU/slave protocol enables seamless integration into broader energy management systems, making it ideal for industrial and utility environments.
