Three-phase meter for measuring a three-wire or four-wire three-phase network via a direct connection up to a maximum of 65 A. The following values are displayed on a seven-segment display with up to 7 digits: active energy (Class 1) and reactive energy (Class 2) for import and export, power, currents, voltages (L-L, L-N), frequency, cos phi, power factor, and apparent power, both per phase and total. Communication can be established via the integrated M-Bus interface or through the infrared interface for connecting a KNX module. The energy meter has 2 fixed-configured inputs and outputs. The output can be used either as a pulse output for active or reactive energy or as an alarm output. Up to 25 alarm values (thresholds with time delay) can be set here. The inputs are used for tariff control or for counting external pulses. The resettable intermediate meter allows for measuring individual intervals. Additionally, the meter can record up to 4 tariffs. The meter is calibrated according to MID and approved according to IEC. The installation width is 4 DIN modules.
