Modular energy meter for DIN rail mounting

Suitable for measuring in all levels of TN & TT networks as well as in IT networks with voltage transformers to record current, voltage, frequency, active, apparent, & reactive power (per phase & total) in the frequency range 45 - 65 Hz, power factor & cos phi, referred reactive & apparent energy as well as referred and delivered active energy (4-quadrant measurement) in separate memory values, continuous true effective value measurement (True RMS).


Can be expanded with a maximum of one expansion module of the type "Module 806-EC1", "Module 806-EI1" and "Module 806-ED1" that can be plugged in on the right side. A maximum of 3 expansion modules of different module types can be connected to a basic device.


Measurement of voltage asymmetry, total harmonic distortion (THD-I & THD-U) and individual harmonics up to the 31st harmonic.


Sampling rate of 8 kHz with 160 measuring points per period & output of the measured values via the interfaces (cycle >=80 ms).
