1. Introduction

the AC currentfeeder is an instrument that converts the measured AC current into a DC currentor voltage that is output in a linear ratio. with the corresponding indicatorinstrument or device, the measurement and control of current and voltage can berealized in the AC circuit of the power system.

the differencebetween FPAR and FPA is the true rms transformation, which does not affect themeasurement accuracy with waveform distortion, so it is especially suitable forareas with severe waveform distortion.

  Modelsand specifications:

FPA: 1 unit of avg. to rms conversion

FPAX: 3 unit of avg. to rms conversion

FPAR: Ture rms conversion

FPAT:Dual output(avg. to rms conversion)

2. Order form

Input & Output parameters

Note:

     1. FPA/FPV can be dual output;

     2. "*" auxiliary power supplyoptional PD1: DC 110V, PD2: DC 220V.

Whensigning the order contract, the required model and specifications should bespecified in detail. the selected model and specifications should be filled inwith the code in the following format.
