The RMU 301-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, 4 MB of memory for storing measurement data, and is highly suitable for installation in busbar distribution boards, making it a reliable and durable solution for energy monitoring in, for example, data centers. Due to its high sample rate, polluting current forms such as those drawn by computer equipment are measured accurately and stably. The meter is also approved for communication with solar converters.
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. In addition, there are three current measurement inputs for current transformers with an adjustable nominal current of 5/1A.
The measuring current ranges from 0.005 to 6 A. For easy integration with other systems, the energy meter is equipped with an RS485 interface that supports Modbus RTU/slave communication. This allows the meter to be remotely read and managed, making it an ideal choice for data centers and industrial, utility applications.
