ABB Stotz S&J Measuring Transformer Meter A42 312-100: additional details
AC meter for measuring single-phase networks 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, current, voltage (L-N), frequency, cos phi, power factor, and apparent power. Communication can occur via the integrated RS485 interface or through the infrared interface. The energy meter has 2 fixed configured inputs and outputs. The output can be used either as a pulse output or as an alarm output, with up to 25 alarm values configurable. The inputs are used to control the tariffs or to count external pulses. The resettable intermediate meter allows for measuring individual intervals. Additionally, the meter can capture up to 4 tariffs. The meter is calibrated according to MID and approved according to IEC. The installation width is 4 DIN modules.
