The fully compliant harmonics and flicker analyzer
The EM Test DPA 503N is a fully compliant analyzer for harmonics and flicker as per the latest IEC/EN 61000-3-2, IEC/EN 61000-3-3 and JIS C 61000-3-2 as well as IEC/EN 61000-3-11 and IEC/EN 61000-3-12:2011 requirements. The DPA 503N has six independent input channels; three for voltage and three for current. It follows the design specifications as per IEC/EN 61000-4-7:2009 (for Class A instruments) for harmonics analyzers and IEC/EN 61000-4-15:2010 for flicker meters.
Based on a real-time kernel and equipped with its own harddisk it allows to record the measuring data continuously without any gaps or overlapping. The rectangular measurement window is synchronised to each group of 10 or 12 cycles of the mains supply frequency (50Hz or 60Hz) by means of a digital PLL (Phase Lock Loop). A wide-range current input (up to 140A) avoids loss of measured data due to range switching that would occur when using different shunt resistors.
The classification of the measurement can be selected at any time, before or after the measurement has been performed. During all measurements the AC supply voltage is measured simultaneously with the current.
Compliance Test Studio 23 – the control and analysing software for harmonics and flicker
Compliance Test Studio 23 (CTS 23) is the software tool needed for the operation of the harmonics and flicker analysing system. It offers all features to control the DPA 503N and AIF 503N, to upload the recorded measuring data and for the classification and analysis. It includes analysis as per the latest standards as well as procedures following the former standard requirements. An easy Fail/Pass function allows fast analysis while detailed data is available for extended analysis and EUT evaluation purposes. CTS 23 offers a powerful documentation capability with direct export to Word, PDF and other file formats.
