▼Chapter 2Universal measuring instrumentUMG 103 universal measuring devicefor DIN rail mountingThe UMG 103 is a very compact universal measuring instrument formounting on DIN rails. The compact dimensions even enable installationin limited spaces such as in installation sub-distribution boards.Installation and connection costs are significantly reduced by mountingthe instrument on a 35mm DIN rail.In order to make use of the extensive functions of modern measuringinstruments, the interconnection and central analysis of data plays animportant role. This is the reason for not using a display; two LEDs showthe current operating status. The communication of measurement datatakes place through a very fast RS485/Modbus interface.The UMG 103 performance level is usually sufficient for sub-measurementsin connection with higher performance power analysers such as the UMG 604 or the UMG 508 applied in more complexenergy management systems. In this case, the UMG 103 serves as data measurement point which takes the measurement data andpasses it on to a higher-level point (master device). Using power analysers such as the UMG 604 with an integrated Modbus/Ethernetgatewayand integrated web server, data are brought onto the Ethernet level or are visualised on the homepage. Some examples ofapplications are cost centre management systems in office buildings, monitoring feeders to sub-distribution panels, motor control centresor in IT and data centres.▼Main features Measurement in TN and TT networks 3 voltage measurement inputs (300V CATIII), 3 current measurement inputs Continuous scanning of the voltage and current measurement inputs High measurement accuracy, effective energy class 0.5; U/I, 0.2% Harmonic analysis up to the 25th order Including GridVis software RS 485 (Modbus RTU, slave) Mounting on 35mm DIN rail Suitable for integration in installation distribution panelsApplicationsThe UMG 103 is intended for the measurement and calculation ofelectrical parameters such as current, voltage, power, consumptionor harmonics etc. in building installations, on distribution panels,on circuit breakers and on server racks. The UMG 103 is fixed intocabinets or small installation distributors in any installation position.The measurement values can be read out using the serial interface.The highest, lowest and energy values are recorded every twoseconds in a non-volatile memory. The voltage measurementinputs are designed for the measurement in low voltage networksin which nominal voltages up to 300V against ground andsurge voltages up to over voltage category III can occur. TheUMG 103 is mainly suitable for measurements in low voltagenetworks because it takes the supply voltage from the measurementvoltage and a voltage converter would be thereforenecessary for HV grids.13
