SINGLE-PHASE NETWORK ANALYSER Z203-1

The Z203-1 module is a single-phase electric-line analyzer for line voltage up to 500 Vac and line current up to 5A (35 Hz to 75 Hz). The module has an analogue output, electrical value directly proportional to selected input: voltage-type out or current-type out. The electrical value (output) is available on screw terminals and the normalized value is available on RS485 registers. A digital output is available, too, to generate a number of pulses depending on the energy increment.

Description

    It is possible to detect, with reference to the electric line and load connected to its: RMS voltage, RMS current, active power, reactive power, cos, frequency, energy.

    A FeRAM allows to recovery the energy if a black-out occurs.

    Energy counter: pulse digital output, reading on Modbus register.

    It is possible to change electrical start/end scale by Dip-switch (see table 1, for each type of retransmitted output) or by Modbus registers (every value).

    Normalized start/end scale between 0..+10000 (for RMS voltage, RMS current, active power), 350..750 (for frequency) or between 0..+10000 (for absolute values of reactive power, cos. isn’t possible to associate a normalized value to the energy quantity.
