In addition to the features of the A210 / A220 this power monitoring device provides functions for system and load analysis.

The system and load analysis is done by measurement of harmonics, THD, asymmetry, comprehensive average and max./min. values.

The A230 is designed for application in high, medium and low voltage systems. Any current and voltage transformers are taken into account in the calculation of the measured values.
