PDF Instruction 1
PDF Instruction 2
The Janitza UMG 96-PQ-L-LP is an advanced, modular power analyzer optimized for precise energy management and power quality analysis in compact distribution systems. Equipped with dedicated low-power current inputs supporting 333 mV transformers and passive Rogowski coils (such as 100 mV/1 kA), it removes the need for bulky converter terminals, significantly saving cabinet space and reducing installation costs.
Featuring high-resolution signal processing with 280 sampling points per wave, the device captures harmonics up to the 65th order and records full-wave events with 20 ms RMS resolution. Its intelligent 64 MB memory partitioning allows storing long-term energy trends up to 15 years alongside high-resolution short-term PQ events without data loss.
Integrated RS485 and optional Ethernet module enable seamless Modbus RTU/TCP gateway functionality. The device offers 50 configurable comparators, color graphic display with oscilloscope waveform visualization, and RCM residual current monitoring capability for complete network transparency.
Application Scope
- Energy management systems compliant with ISO 50001 standards
- Retrofit installations using flexible passive Rogowski coils
- Continuous power quality monitoring up to the 65th harmonic
- Residual current monitoring (RCM) and temperature supervision
- Sub-metering and cost-center allocation with Class 0.5S precision
- Compact switchboard panels with space-constrained DIN layout
