AMC Series electric meter

AMC72L-AI3 Programmable Intelligent Electric Parameter Meters--Three phase current

Adopting AC sampling technology, can measure many single phase or three phase grid electrical parameters such as current, voltage, power, electric energy etc. directly or indirectly. It can be used for local display, and also can be connected with the control equipment to form measuring and controlling system.
Fitted with RS-485 communication port, adopting Modbus-RTU protocol. Meters can switch electric parameter signal into standard analog output, with four-channel (two-channel) switching input / two-channel switching output. Based on different requirements, by keys on the faceplate, electric parameters for transformation ratio, alarm, communication etc. can be set up and controlled.

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.
