1.1  개요 

MPM 330 Power Meter는  3상  전기의  계측을  정확하고  신속히  측정  할  수  있도록  MPU를  채택하여  설계되어 

있다. MPM 330은  다음의  전기량  계측  항목(2.2측정항목)을  수용하고  있으며,  전면부의  FND  혹은  통신방식을 

이용  계측  항목을  표시  할  수  있다.  또한  Galvanic Isolation  처리가  되어,  외부  써지나  노이즈에  강하게  설계 

되어  있다. 

       

1.2  통  신 

  통신은  2 Wire  방식의  Half Duplex RS-485  통신  모듈을  가지고  있다. RS-485는  멀티드롭  방식  이며,  하나의 

통신라인에  99개의  장비까지  연결이  가능하다.  거리가  100m  이상일  경우  종단저항  120  오옴  설치를  권장한다.   

 

1.3  제어용  전원 

  AC, DC  겸용으로  내부에  스위칭  Power Supply가  내장되어  있어  전원  인가  시  매우  안전하다. 

☞  AC전원  입력  범위  : 90Vac ~260Vac    50~60Hz 

☞  DC전원  입력  범위  : 110Vdc ~300Vdc 

 

1.4  전압  입력  및  전류  입력  사양 

전압  입력  :  상  전압      – 270Vrms 

선간  전압  - 470Vrms   

전류  입력  : 5A     

☞  참고  :  입력  전압  최대치의  10%와  입력  전류  최대치의  50%가  초과  하여도  기기에  직접적인  문제는  없으나 

정확한  전기량  측정이  불가  하므로  주의해야  한다.  또한  Galvanic Isolation  처리가  되어  외부  써지나  노이즈에 

강하게  설계되어  있다. 

 

1.5  정밀도 

☞  전압 

          : 0.3 % 

☞  전류 

          : 0.3%     

☞  유효전력            : 0.5 % 

☞  피상전력            : 0.5 % 

☞  무효전력            : 0.5 % 

☞  역률                    : 0.5 % 

☞  주파수                : 0.5 % 

☞  유효  전력량      : 1.0 %
