Network analyzer Series ION7400 for front mounting in low and medium voltage applications without display. Mounting on DIN rail, accuracy class 0.2S. 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, communication, or contact. Current, voltage (average and per phase), current average, active, reactive, and apparent power, power factor (total and per phase) power averages. Frequency, minimum and maximum values of instantaneous values, maximum values of current and power averages. Harmonic content THD I, THD U, and TDD, harmonic analysis measurement values per phase with bar chart up to the 127th via software. Harmonics displayed on the device, up to the 63rd threshold monitoring and alarming: self-learning threshold with alarm via display or communication. 52 data loggers with 16 channels each for recording true RMS values (minute, second, or 10ms values), event logger with timestamp in milliseconds. Advanced disturbance recording function for power network oscillography in case of events with up to 256 samples per cycle for various trigger events via EcoStruxure Power Monitoring Expert with recording duration over 210 cycles or more than 4 seconds at high sampling rates. High storage depth with 512 MB. Note: I/O modules, display, and spare parts for ION7400 use the accessories of the PM8000.
