The ION9000 power analyzers feature 4-quadrant measurement capabilities. They allow for the import and export of active and reactive energy, with active, reactive, and apparent energy meters per phase. Additionally, there are separate active energy meters with tariff selection via a weekly timer. The device provides voltage measurements (average and per phase), the average current value, active, reactive, and apparent power, as well as the power factor (total and per phase). It also displays average power values, frequency, minimum and maximum values of instantaneous readings, as well as maximum values for average current and power. The harmonic content includes THD I, THD U, and TDD, with harmonic analysis showing 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). The device uses a low-voltage current transformer with options for 0.333 V or 1 V and a supply voltage of 20-60 V DC. It complies with the standards EN 50160, IEC 61000-4-30, and IEC 519.
