| Artikelbeschreibung | Modular network analyzer with MODBUS rtu / 230V AC, it network / modular network analyzer class s / suitable for measuring in all levels of TN, TT & it networks for recording current, voltage, frequency, active, apparent & reactive power (per phase & total) in the frequency range of 45-65 HZ, cos phi, active, apparent & reactive energy total as well as consumption and output of active & reactive energy (4-QUADRANT measurement) in separate memory values as well as 2 tariffs, continuous true RMS measurement. Suitable for measurement in it networks up to 600V. Five comparator groups for logical evaluation (and / or, etc.) of 10 direct measured values each or resulting measured values with parametrizable lead and switch-on time as limit value switches (limit value monitoring, etc.) with a cycle of >= 200 MS. Digital drag indicator function (positive/negative) for active and apparent power as |
