EM TEST DPA 500N Digital Power Analyzer for Harmonics & Flicker Testing
Description
EM TEST DPA 500N Digital Power Analyzer 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 requirements. It follows the design specifications as per IEC/EN 61000-4-7: Ed.2.1 (2009) (for Class I instruments) and IEC/EN 61000-4-15 (2010).
Based on a real-time kernel and equipped with its own hard disk it allows to record the measuring data continuously without any gaps or overlapping. The rectangular measurement window is synchronized 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 50A) avoids loss of measured data due to range switching that would occur when using different shunt resistors.
The built-in flicker impedance, which is automatically selected when doing flicker measurement, makes the DPA 500N a complete single-box unit for both harmonics and flicker analysis.
