Janitza UMG 96RM-PN Power Quality Analyser with Profinet, 90-277V 5222090

The Janitza UMG 96RM-PN is a panel-mounted power quality analyser that delivers comprehensive measurement of voltage, current, power, energy, harmonics, THD, flicker, and unbalance in three-phase systems. Its standout capability is high-accuracy energy metering (Class 0.2S) combined with Profinet connectivity for seamless integration into industrial automation networks.

Advantages

With a 20 kHz sampling rate per channel and harmonic analysis up to the 63rd order, this device captures detailed power quality data. The 256 MB internal flash memory enables extensive data logging, while the graphic LCD provides clear on-site visualisation. Dual communication interfaces (Profinet and RS485 Modbus/RTU) ensure flexible integration, and the wide auxiliary voltage range (90-277V AC / 90-250V DC) suits diverse installations.
