Overview

The type of operating principle of these meters are the transducer type and also the meter divide into the balanced power factor meter and the unbalanced power factor meter.

Model

Features

ㆍOperating voltage range : rated voltage ±10%

ㆍFor other voltage and/or current ratings higher then listed in specification use external C.T and/or external P.T with a 110V/5A instrument.

ㆍThe instrument of D-P□□□T Type is self contained with the Transducer Box.

ㆍRating voltage of 3phase 4wire is at phase voltage.(/√3)

ㆍThe meter do not operate when load current is under 10% of rated current.
    And if the circuit current is less than a 1/3 of the dating (or less than 1.66A if the rating is 5A) the error of P.T meter may have happened more than that of rated current.

ㆍStandard scale : Lead 0.5~1.0~0.5 Lag
