High power, low price: Power analyser with residual current monitoring (RCM)

The power analyser UMG 509 for front panel installation is equipped with a large colour graphic display with intuitive user guidance. Its comprehensive measurement functions (e.g. short term interruptions, start-up currents, transients, harmonics up to the 63rd harmonic) are rarely seen in this price class - particularly not in combination with residual current monitoring. With this the user can detect fault sources in a timely manner, e.g. before an insulation fault leads to a system failure. 

Comprehensive communication options such as RS485 (Modbus RTU, Profibus), Ethernet TCP/IP, BACnet (optional), HTTP, FTP, SNMP, SMTP, SNTP or DNS enable cost-efficient and rapid integration in existing communication architectures.

Measurement takes place via 4 separate current inputs, be it for additional measurement in the N or PE, or for the measurement of 4 single-phase consumers. The UMG 509 is equipped with a separate consumption meter per current input. The large measurement storage capacity of 256 MByte enables the logging of all measured values over a period of months, also without interim read-outs. 

The high resolution graphic display provides online graphs, FFT with harmonics displayed in bar charts, clear presentation of the monthly kWh values, alarm management / event display with date and time stamps and many other functions. 

The device-specific homepage for the measuring devices is ideal for users or target groups within a company, who do not wish to install the GridVis® software or do not require it. For access to this, the user simply requires a conventional web browser and an Ethernet connection (or a local patch cable). 

The UMG 509 utilises the BACnet protocol for use in building communication.
