Power Meter S203TA

The S203TA module is a three-phase network analyzer for electric-line voltage up to 600Vac and electric-line current up to the current transformer rated current (50 Hz or 60 Hz). The module has an analog output, electrical value directly proportional to selected input: voltagetype output or current-type output. The electrical value (analog output) is available on screw terminals and the normalized value is available on RS485 registers.


It is possible to detect, with reference to the electric-line and load connected to its: RMS voltage, RMS current, active power, reactive power, apparent power, cos, frequency, energy (for each measure: phase A, phase B, phase C and three-phase values are available, except frequency).

Normalized start/end scale between 0..+10000 (for RMS voltage, RMS current, active power, apparent power) or between ± 10000).

It is possible to reset the energy values.

It is possible to manage connections for high power devices using current transformers (with secondary current=5Arms)

It is possible to connect the module using single-phase insertion, ARON insertion (three-phase without neutral), 4-wires insertion (three-phase with neutral), single-phase without CT insertion. It is possible to configure the module (node) address and baud-rate by Dip-Switches. It is possible to configure electrical-line frequency, output (electrical value), single/three phase application, rescaled-input type, insertion-type and maximum current by Dip-Switches.
