PQ Plus UMD 913 Digital rack-mount meter
The UMD 913 is a powerful, multi-functional, high-precision measuring instrument for panel mounting. It is Class A certified. It measures 4-phase current and voltage in 4-quadrant operation, in class 0.05 and thus the work in class 0.2 s. No matter what happens in energy systems, thatNetwork analyzers UMD 913 register even the smallest faults or changes. All parameters of the electrical power supply are recorded without gaps and precisely. Detailed quality evaluations make even the smallest deviations visible and provide information on the causes of the faults. The exact time synchronization of the measuring systems by means of GPS or NTP enables the merging of measured data for a comprehensive monitoring of the entire supply network. For the analysis and documentation of the power quality according to self-defined or international standards such as EN 50160, EN 61000-2-2, EN 61000-2-4 or EN 61000-2-12 UMD systems permanently record all network parameters. High storage capacities and effective compression methods allow long-term recordings of up to several years. In addition to the continuous recording of all parameters relevant for power quality, the integrated fault recorder module allows event-triggered recording of transient processes with sampling rates of up to 28.8 kHz. It comes individually or nationwideUsed in conjunction with the key points of all voltage levels. The measured value monitoring is comprehensive, complete and fully automatic.This text is machine translated.
