The ION9000 power analyzers feature four-quadrant measurement, enabling the import and export of active and reactive energy. They include active, reactive, and apparent energy meters per phase, as well as separate active energy meters with tariff selection via a weekly timer. The device provides voltage measurements (average and per phase), average current values, and displays active, reactive, and apparent power along with the power factor (total and per phase). It also shows average power values, frequency, minimum and maximum values of instantaneous readings, as well as peak values of average current and power. The harmonic content is measured with THD I, THD U, and TDD. A harmonic analysis is available, with measured values per phase displayed in a bar chart that extends to the 63rd harmonic on the device display and up to the 511th harmonic via software (1024 measured values per cycle). The device is compatible with low-voltage current transformers of 0.333 V or 1 V. Compliance standards include EN 50160, IEC 61000-4-30, and IEC 519.
