Available from Westek Electronics , the new Janitza, DIN-rail mounting, UMG 511 power quality analyzer provides continuous 24/7 monitoring and analysis of single and three-phase, three and four wire networks in accordance with EN 50160. 

The power quality analyzer can be used as a protective relay as well an Ethernet gateway in hierarchical analysis and control networks. The UMG 511 power quality analyzer measures 4 voltages and 4 currents thus providing complete information for 4-wire three-phase systems, including neutral conductor parameters. 

The UMG 511 power quality analyzer measures transients (from 50 µs), flicker, voltage unbalance, event detection, and harmonics from the first to the 63rd harmonic for voltage and current as well as interharmonics. 

Additionally, three-phase parameters are analyzed in positive, negative and zero phasor sequence. The display methods include phasor diagrams in terms of symmetrical components, waveforms for voltage and current, harmonic bar graph display, rms trend values over time, and numerical values.

The UMG 511 power quality analyzer is equipped with 256 MB flash memory for events and transients, 5 digital outputs and 8 digital inputs as well as an embedded webserver interface. Additionally RS 485 / Fast Ethernet 10/100Base-TX and Profibus DP V0, Modbus RTU, Modbus TCP, as well as Modbus gateway are provided.
