PDF Instruction 2
The Janitza UMG 512-PRO is a high-performance power quality analyzer certified strictly according to IEC 61000-4-30 Class A standards. Designed for continuous monitoring in critical industrial and commercial electrical distribution networks, this flagship device ensures full compliance with EN 50160, IEEE 519, and EN 61000-2-4 standards. With continuous sampling at 25.6 kHz and 512 measurement points per cycle, it captures even the fastest transient events down to 39 microseconds.
Featuring advanced residual current monitoring (RCM) with 2 dedicated channels and an integrated thermistor input, the UMG 512-PRO provides comprehensive fault prevention before outages or electrical hazards occur. Its embedded web server, 256 MB internal memory, and vast communication protocols including BACnet, Modbus TCP/RTU Gateway, and Profibus DP V0 allow effortless integration into existing Building Management Systems and industrial Automation platforms.
Scope of Application
- Continuous power quality monitoring according to EN 50160 and Class A standards
- Residual current monitoring in TN-S systems and critical data centers
- Transient and fault recording in high and medium voltage switchgear
- Building management and energy automation via BACnet and Modbus Gateway
- Peak load management and power disturbance analysis in manufacturing plants
