SINEAX U 553 Transducer for AC Voltage

Transcription

1 With power supply RMS value measurement Carrying rail housing P/0 Application he transducer SINEAX U 55 (Fig. ) converts a sinusoidal or a distorted AC voltage into a load independent DC current or a load independent DC voltage proportional to the measured value. he transducer fulfils all the important requirements and regulations concerning electromagnetic compatibility EMC and Safety (IEC 00 resp. EN 00). It was developed and is manufactured and tested in strict accordance with the quality assurance standard ISO 00. Features / Benefits Measuring input: AC voltage, sine or distorted wave forms, RMS value measurement Measured variable AC voltage Measuring range limits 0 0 to 0 0 V Measuring output: Unipolar and live-zero output variables Measuring principle: Logarithmic method AC/DC power supply / Universal Standard version as per Germanischer Lloyd Fig.. ransducer SINEAX U 55 in housing P/0 clipped onto a top-hat rail. he output amplifier transforms the measuring signal into an impressed DC current output signal A. he electronic components are supplied with voltage H from the mains supply unit H. U~ Ueff = o u dt A H Mode of operation Input signal U~ is galvanically separated from the mains network using a transformer. he following mathematical expression is then formed using a root-mean-square value computer Ueff = u dt o Following filtration by means of an active filter, the transformation properties of the measuring transducer are determined in the succeeding characteristics circuit.
