ABB Stotz S&J Measuring Transformer Meter A44 212-100: additional details
Three-phase meter for measuring a three-wire or four-wire three-phase network via a transformer connection CTVT (transformer ratio for current and voltage configurable) up to a maximum of 6 A. The following values are displayed on a white backlit 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 occur via the integrated RS485 interface (Modbus RTU) or through the infrared interface for connecting a KNX module. The energy meter has an output that 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. The meter is calibrated according to MID and approved according to IEC. The installation width is 7 DIN modules.
