FPV&FPVX AC VOLTAGE TRANSDUCERS

Power transducer FP series power Transducer

Quick Overview

The AC current feeder is an instrument that converts the measured AC current into a DC current or voltage that is output in a linear ratio. With the corresponding indicator instrument or device, the measurement and control of current and voltage can be realized in the AC circuit of the power system.

1.Introduction:

The AC current feeder is an transducer that converts the measured AC VOLTAGE into a DC current or voltage that is output in a linear ratio. With the corresponding indicator instrument or device, the measurement and control of current and voltage can be realized in the AC VOLTAGE of the power system.

The difference between FPVR and FPV is the true rms transformation, which does not affect the measurement accuracy with waveform distortion, so it is especially suitable for areas with severe waveform distortion.

  Models and specifications:

FPV: 1 unit of avg. to rms conversion

FPVX: 3 unit of avg. to rms conversion

FPVR: Ture rms conversion

FPVT:Dual output(avg. to rms conversion)
