Transformer kilowatt-hour meter 1A A42 552-120 – ABB – 2CMA170518R1000 – 7392696705189: Instrument transformer meter RS485 A42 552-120 Electronic meter type, rated current (In) 1A, maximum current (Imax) 6A, rated voltage (Un) NL 57.7 ... 288V, frequency 50 ... 60Hz, accuracy class C, polarity 1-phase, version Measuring converter, energy type active and reactive power, suitable for purchase/supply, tariff design multi-tariff, tariff control internal/external, measurement type load profile, backstop, calibrated, approval Measuring Instruments Directive, pulse output electrical, pulse type S0, pulse rate 5000 ... 5000Imp/kWh (kvarh ), digital display type, REG mounting type, width in pitch units 4, design of the RS-485 interface, number of digits 7, degree of protection (IP) IP20, degree of protection (NEMA) other, AC meter for measuring single-phase 16.7 Hz networks via a Converter connection CTVT (configurable converter 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 1) and reactive energy (class 2) for import and export, power, current, voltage (LN), frequency, cos phi, power factor and apparent power. 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 resettable intermediate counter enables individual intervals to be measured. In addition, the meter records up to 4 tariffs. The energy meter measures currents and voltages up to the 16th harmonic and uses it to calculate the total harmonic distortion. Meter is calibrated according to MID and approved according to IEC. The installation width is 4 DIN modules.
