Description:

The S203TA is a complete three-phase network analyser suited for use with up to 600V AC voltage range, and current range given by the nominal range of the CTs with 5AOutput connected. The instrument provides all the following electrical measurable quantities: Vrms, Irms, Watt, Var, Va, Frequency, Cos and Active Energy.

All measurements given above (except frequency) are available both single-phase and three-phase. Measurements are read through serial communication both in floating point and normalised format (except Frequency and Active Energy).

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 MODBUS registry).The module is also distinguished by:

Communication configurability through DIP-switch or software.
RS485 serial communication with MODBUS-RTU protocol, maximum 32 nodes.
Easy-wiring of power supply and serial bus by means of the bus housed in the DINrail.
High precision: 0,2%class.
Protection against ESD discharge upto 4kV.
Power input insulation: 3750Vac towards all the other circuits.
Insulation between communication and power supply: 1500Vac.
Insulation between retransmitted output and power supply: 1500Vac.
Analogue output signal settable in voltage or current.
Possibility for connection and management by external CTs with 5A output.
All kind of insertion possible: single phase, Aron(three-phase with 2CTs), four wires(three-phase with 3CTs).
Possibility to compensate errors caused by frequency change in places where network frequency is not stable (frequency changes>30mHz).
