1. General 

AMC Series programmable intelligent three phase current, voltage meter, adopting AC sampling technology, can 

directly  measure current and voltage  of  three phase grid.  It can be used for local display,  and connecting industrial 

control device to form measuring control system. 

Meters  have  RS-485  communication  interface,  adopt  compatible  Modbus-RTU  protocol;  can  change  electric 

parameter  signal  into  standard  analog  output;  or  with  l  channel  relay  alarm  output;  or  with  4  channel  (2  channel) 

switching input/ 2 channel switching output Based on different request, by pressing related keys on instrument panel, 

parameter setting and control of transformation ratio, alarm, communication etc. can be done.
