The module ME110-230.3M is an input module for measuring the electrical data in a 3-phase AC power system and transmission of the measured and calculated data over RS485 network.
The device has three voltage analog inputs and three current analog inputs. The phase currents, phase voltages and line-to-line voltages are measured on inputs and digitalised. The digitalised values are used to calculate the effective (root mean square) values and other 3-phase AC power system values: powers (active, reactive, apparent), power fac-tors and phase angles.
