PDF Instruction 2
The Janitza UMG 96-PQ-L is an advanced modular network analyzer designed for comprehensive power quality analysis and energy management. Equipped with active energy measurement accuracy of class 0.2S and 64 MB onboard flash memory, this device guarantees detailed recording of full-wave events, voltage dips, and harmonics up to the 65th order over extended operating periods.
Featuring integrated residual current monitoring (RCM) and direct temperature measurement capabilities, the analyzer ensures proactive system safety and equipment protection. Its high-resolution color graphic display allows intuitive local visualization of phasor diagrams, oscilloscope wave shapes, drag indicators, and real-time status alerts.
With full support for IEC 61000-4-30 Class S standards, standard-compliant assessment according to EN 50160 and IEEE 519 is achieved effortlessly. Integrated Ethernet and RS485 communication interfaces with Modbus Gateway function ensure seamless integration into industrial automation networks and GridVis energy management software.
