GeneralDescription
ModelS203TAisacompletethree-phasenetworkanalyzersuitedfor use with up to
600Vac voltage range, and current range given by the nominal range of the CTs with 5A
Outputconnected.
The instrument provides all the following electrical measurable quantities: Vrms, Irms,
Watt, Var, Va, Frequency, Cos Active Energyand . All measurements given above
(exceptfrequency)areavailablebothsingle-phaseandthree-phase.
Measurements are read through serial communication both in floating point and
normalisedformat(exceptFrequencyandActiveEnergy).
The DIP-switches can be set for the analog retransmission of any Vrms, Irms, Watt and
Cos quantity either single phase or three-phase, or any phase chosen (by specific
MODBUSregistry).Themoduleisalsodistinguishedby:

Operatinglogic
The module measures the following electrical quantities: Vrms, Irms, Watt, Var, Va,
Frequenza, Cos and Active Energy, and provides the values in the corresponding
MODBUSregisters.
In three-phase environments, measurements given above corresponding to any phase
areavailable,otherthanthethree-phasevalue(exceptthefrequencyofcourse).
These measurements are rendered in both floating point and normalised format (except
Frequency and Active energy) between 0 - +10000 (-10000 - +10000 for VAR e Cos ).
Active energy value is stored in memory and when the instrument is switched off, the last
valuebeforeswitchingiskeptinmemory.
The module output can transmit, via DIP-switch setting, one of the following quantities:
Vrms,Irms,Watt,cos aseitheracurrentorvoltagevalue.Iftheinstrumentissetforthree-
phase measurements, it transmits automatically the three-phase value of the selected
measurement. However, via MODBUS register, the user can choose to transmit the
measurementcorrespondingtoanyphase:A,B,C.
The user can set through MODBUS the values and of the measurement toMIN MAX

Measurement and retransmission range
V range,(therefore ), then if Vrms measured is 10V, analog output willMIN=10, MAX=300
be 4mA, while if Vrms=300V outputwill be 20mA. In the intermediate points the behaviour
is linear. The retransmission values saturate at approximately 11 V for voltage output and
at22mAforcurrentoutput(analogoutputclampedat110%).
If network frequency oscillates more than 30 mHz from rated values (50 o 60 Hz), it’s
possibile to compensate errors on measurements of Power and Energy caused by these
variations.This option is selectable via MODBUS register. Vrms and Irms measurements
arenotinfluencedbythesevariations.
When the module is switched on, the appropriate setting coefficients are measured
(depending on the choice of 50 or 60 Hz frequency). All the settings made will be
automaticallyloadedwhenthemoduleisreset.

The module provides an analog output in voltage (0..10 Vdc, 0..5 Vdc) or active and
passive current (0..20 mA, 4..20 mA). We recommend using shielded cables for the
electricconnections.
(1) Passive Output already powered to connect to passive inputs.
(2) Passive Output not powered to connect to active inputs.

RETRANSMITTED OUTPUT: FACTORY SETTINGS
the device is configured by default to retransmit on the analogue output the
THREE-PHASE POWER measured on a 4-wire connection (three phase +
neutral).
The parameters are as follows:
P.tot. W = 9000 = Out 4 .. 20 mA; I TA = 5 A; V = 600 Vac
This configuration allows you to get maximum power with external TA ratio 1:1
(WARNING: the external TA is always necessary because the instrument
performs the measurement of current through not isolated internal shunt).
Clearly the power is related to a voltage of 600 V measured between phase
and neutral, in the case of lower voltage, typically 230 VAC between phases
and neutral, the output will never reach the value of 20 mA and will stop at a
maximum power of 3450 W which corresponds to 10.13 mA.
Any change of the values described above, and in particular the re-scaling of
retransmitted output it should be done using the configuration software EASY
SETUP together with the selection of output type using the DIP-switches.
