The DPA 503N from AMETEK CTS is a state-of-the-art Three-Phase Harmonics and Flicker Analyzer, designed according to IEC 61000-4-7 (for Class I) and IEC/EN 61000-4-15 standards. It fully complies with IEC 61000-3-2, IEC 61000-3-12, IEC 61000-3-3, and JIS 61000-3-2/-12 requirements. This analyzer features a wide-range current input (up to 75 A) to prevent data loss during range switching, and its versatile design allows for measurement classification selection both before and after the process. It is equipped with a 16-bit analog-to-digital converter and a built-in lumped flicker impedance. The analyzer enables continuous recording of measuring data without any gaps or overlaps due to its real-time kernel and its dedicated hard disk.

The DPA 503N is managed using .NET software (net.control) and includes USB interface for control and data transfer. This software allows for the comprehensive control of the analyzer, uploading of recorded measurement data, and conducting classification and analysis. It supports both the latest standards and previous standard requirements, featuring a convenient pass/fail function for quick analysis and detailed data availability for extended analysis and Equipment Under Test (EUT) evaluation.
