Mô tả
FCA3000 is a three-channel current converter with DC outputs. It converts the values measured by a Rogowski coil into true RMS value.
FCA3000 can be used with any model or size of MFC150 Rogowski coils, according to the application. The coils can be connected directly to FCA3000 without any adapter, as FCA3000 integrates the input signal, shifting it by 90°. FCA3000 has three indipendent input channels, suitable for three transducers, and four DC outputs. The first three outputs correspond to each transducer, the forth gives the sum of the three current channels.
FCA3000 enclosure is a 9 module DIN rail for fast installation. FCA3000 can be used as current measurement interface with industrial devices such as PLC, SCADA systems, protection systems, control systems, metering equipments etc.
