ION9000 power analyzers including display. Four-quadrant measurement. Import and export for active and reactive energy. Active, reactive, and apparent energy meters per phase, as well as separate active energy meters with tariff selection via weekly timer. Voltage (average and per phase), average current value, active, reactive, and apparent power, power factor (total and per phase). Average power values, frequency, minimum and maximum values of instantaneous values, maximum values of average current and power values. Harmonic content THD I, THD U, and TDD. Harmonic analysis: measurement values per phase with bar chart, up to the 63rd harmonic on the device display and up to the 511th harmonic via software (1024 measurements per period). Low voltage current transformers with 0.333 V or 1 V, supply voltage 20-60 V DC, with 192 mm display. EN 50160, IEC 61000-4-30, IEC 519.
