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.

• Display of all 4 quadrants
• 63 measurands with high accuracy (U, I: 0,5%)
• 2 pulse or trip point outputs (S0)
• Minimal installation depth: 46 mm
• Transformer ratio programmable
