Three-phase meter for measuring a three-wire or four-wire three-phase network via a CTVT transformer connection (configurable transformer ratio for current and voltage) up to a maximum of 6 A. The following values are output via a backlit display with up to 7 digits: active energy (class 0.5) and reactive energy (class 2) for import and export, power, currents, voltages (LL, LN), frequency, cos phi, power factor and apparent power (per phase and total). Communication can take place via the integrated RS485 or infrared interface. The energy meter has 4 individually programmable inputs/outputs. The output can be used either as a pulse output or as an alarm output (up to 25 alarm values). The inputs are used to control the tariffs or to count external pulses. The meter also records up to 4 tariffs. The energy meter measures currents and voltages up to the 16th harmonic and uses this to calculate the total harmonic distortion. The meter is calibrated according to MID and approved according to IEC. The installation width is 7 DIN modules.
