Acrel Amc72L-Dv Panel Type DC PV System Voltage Meter


Display: LCD Installation: Indirect Connected Accuracy: Class 0.5 Power Source: DC Meter Theory: Electronic Meter Application: Electronic Equipment, Electric Power, Telecommunications

  General

AMC series programmable intelligent meters,adopting AC sampling technology,can directly or indirectly measure electric voltage and current of single phase or three phase grid. It can be used for local display,and connecting industrial control device to form measuring control system. This series of meters have RS-485 port,adopt Modbus-RTU protocol. Analog output,alarm output,switching input/ output can be selected. Based on different request,by pressing the keys,parameters of ratio,alarm,communication etc. can be modified.

 

  Notice 

1.Voltage Input The input voltage must not be higher than the rated input voltage of the product ,otherwise PT should be considered A 1A fuse must be installed on the voltage input. 

2.Current Input Current input shall use external CT; If the used CT connected with other meters,the connection should be used in series; It is recommended to use wiring board ,do not connected with CT directly,in order to remove conveniently; Before removing product ‘s current input connection,be sure to disconnect the CT primary circuit or short the secondary circuit. 

3.Additional function wiring 7 COM of analog output and switching input represent their own common end,it is not earthing actually. Two-core shield cable is recommended for communication connection. Its wire diameter is not less than 0.5mm2 ,connecting A B respectively ,shielded layer single point to connect the earth or dangling .When wiring,the communication line shall be far away from strong current cable and other strong electric field environment.
