UMG503 Universal Measuring Device
The UMG503 is a universal measuring device, which is suitable for measurement, storage and supervision of electrical quantities in low and medium voltage networks. The measurement is laid out for 1 and 3 phase systems with or without neutral conductor (option). One of its main features is the high accuracy class, compact design and the measurement of the harmonic voltages and currents in each outer conductor. The UMG503 is an amperemeter, voltmeter, voltmeter-change over, power meter (kW, kVA, kVAr cos), real and reactive work for four tariffs (consumption/supply), harmonic analyser and measurement transformer, clock, etc all in one unit and due to this the costs for the project, installation, wiring and storage are much lower.
Measuring Value Indication
The easy to read LCD data field in combination with the function keys, informs the user about the selected measured values (actual /lowest /highest /mean values). With the UMG503 you can indicate 3 measured values in the display and create 150 data fields individually via the supplied software PSW503.
Software
The programming and evaluation software PSW 503 is included in the contents of delivery. For online measured value collection, the visualisation and evaluation software AWS 485 Win is available separately.
