AMC72-DV Измеритель напряжения постоянного тока

Программируемые интеллектуальные счетчики серии AMC, использующие технологию отбора проб постоянного тока, могут прямо или косвенно измерять электрическое напряжение и ток в однофазной или трехфазной сети. Его можно использовать для локального отображения и подключения промышленного устройства управления для формирования системы измерительного контроля.

FAQ




Q: No display on power?


A: Check whether the supply voltage is within the operating voltage range.



Q: Incorrect reading of voltage,current,electricty,etc?


A: Checking that the voltage/current ratio setting are correct;

     Checking whether the wiring mode setting is consistent with the actual situation;

     Checking whether the voltage transformer and current transformer are in good condition.




Q: Abnormal communication?


A: Check whether the adress,baud rate,check bits in the communication;

     Setting are consistent with the host computer;

     Check whether the RS485 converter is normal;

     Check the connection is corrent if the resistor above 120 ohm is connected in parallel at the communication end.
