1. General

ACR330EGH is a kind of electrical network analyzer designed by ACREL under the IEC norm, and it has several international advanced technologies.

It can measure all the electrical data in the three phase network, including measurement of multi-rate energy and 4-quadrant energies, harmonic and quality of electrical network analysis, 4 logic inputs, 3 relay outputs and RS485 communication. Therefore ACR330EGH can be widely used in SCADA and DCS system.

2. Characteristics
1, Measuring accurately the data of three phase network, such as phase voltages, line voltages, current, active, reactive and apparent power, power factor etc..; 

2, 4-quadrant energies, including active capacitive energy, active inductive energy, reactive capacitive energy and reactive inductive energy; It can also count the energies in 8 zone times by 3 tariffs (the energies in this month, in last month, in before last month and total energy);

3, Measuring component and THD of the 2~31 ranges harmonic of current and voltage, current K-factor, voltage crest factor, waveform factor, degree of voltage and current unbalance etc.., and users can analyze the electrical network quality with these data;

4, It can be equipped 4 logic inputs, 3 relay outputs, 1 RS485 communication with MODBUS protocol in order to satisfy the demand of measurement and control in long distance.
