PDF Instruction 1
The Janitza UMG 96RM-CBM is an advanced multifunctional power analyzer designed for continuous monitoring and measurement of electrical parameters in low and medium voltage distribution systems. Equipped with a high sampling rate of 21.3 kHz and class 0.5S active energy measurement accuracy, this compact instrument provides unmatched long-term stability and precise power quality analytics.
Featuring an onboard 256 MB measurement data memory capable of recording up to 10,000,000 values, the UMG 96RM-CBM ensures seamless data acquisition with flexible tariff configurations (up to 14 tariffs). Integrated Modbus RTU via RS485 and USB interfaces enable easy integration into building management systems (BMS), PLC, and energy management platforms such as GridVis®.
The unit incorporates a 4th current transformer input for neutral conductor monitoring, harmonic analysis up to the 40th order, battery-buffered clock, 4 digital inputs, and 6 digital/pulse outputs for comprehensive grid control and sub-metering applications.
Areas of Application
- Continuous energy management and load profile recording according to ISO 50001
- Power quality monitoring and network disturbance tracking up to the 40th harmonic
- Cost center energy allocation and multi-tariff consumption analysis
- Transducer for Building Management Systems (BMS), PLC, and SCADA control networks
- Neutral conductor monitoring via dedicated 4th current transformer input
