Product detail
M552 C-Tran Introduction
The M552 C-Tran is a Current Transformer complete with an integrated, fully programmable, three phase power transducer. It provides two isolated RS485 communication ports both using Modicon’s Modbus protocol.
The transducer’s accuracy is class 0.2% for voltage and current signals down to 10% Un and 10% In, class 0.3 for power measurements and 1% of reading for energy measurements. (IEC1036), 50-60Hz.
The CT is class 1%
The M552 C-Tran measures Voltages, Currents, Import/Export Power (W, VAr, VA), True Power Factor, Frequency, Import/Export Demands(Wd, VArd, VAd, Ad) and Import/Export Energy and Hours Run
All measured quantities can be obtained from the transducer, the system’s parameters can be set up remotely, important data can be saved to computer and the order of the Modbus registers themselves can be changed.
A second RS485 port can be used to drive up to 31 LCD meter style terminals.

M552 C-Tran
The M552 C-Tran is a Current Transformer complete with an integrated three phase, RMS sensing, multifunction AC power transducer.
The M552 C-Tran is fully programmable through one of its two communication ports.
The M552 C-Tran can drive a number of LCD meter terminals using its second RS485 network.
The accuracy of the M552 transducer is Class 0.2 to IEC 688 over the range 10% to 120%.
For Active and Reactive energy the accuracy is 1% of reading to IEC 1036.
The CT is a Class 1
