Three-phase meter for measuring a three-wire or four-wire three-phase network via a direct connection up to a maximum of 80 A. The following values are output via a backlit display with up to 7 digits: active energy (class 1) and reactive energy (class 2) for import and export, power, currents, voltages (LL, LN), frequency, cos phi, power factor and apparent power, both per phase and total. Communication can take place via the integrated M-Bus interface or via the infrared interface. The energy meter has 2 permanently configured inputs and outputs. The output can be used either as a pulse output or as an alarm output. Up to 25 alarm values can be set here. The inputs are used to control the tariffs or to count external pulses. The resettable intermediate counter enables the measurement of individual intervals. The meter also records up to 4 tariffs. The meter is calibrated according to MID and approved according to IEC. The installation width is 7 DIN modules.
