The ION9000 power analyzers feature a display and offer 4-quadrant measurement. They support the import and export of active and reactive energy as well as active, reactive, and apparent energy meters per phase. There are separate active energy meters with tariff selection via a weekly timer. The device measures voltage (average and per phase), average current value, active, reactive, and apparent power, as well as the power factor (total and per phase). It also provides average power values, frequency, minimum and maximum values of instantaneous measurements, and peak values of average current and power. The harmonic content includes THD I, THD U, and TDD, with harmonic analysis displaying the measured values per phase in a bar chart, up to the 63rd harmonic on the device display and up to the 511th harmonic via software (1024 measured values per period). It features a low-voltage current transformer with 0.333 V or 1 V and a 192 mm display. Compliance standards include EN 50160, IEC 61000-4-30, and IEC 519.
