overview

Suitable for AC charging stations with low functional requirements, mainly low-power slow charging, and compact internal layout;

main features

DDM1778The series metering module adopts separate electrical isolation, which has the advantages of high-precision metering, high and low temperature adaptation, high stability, reverse current protection, etc. It is compact in size and can be flexibly installed in metering occasions such as small charging piles;

major function

Ø It can measure voltage, current, and power, and can store active energy for 12 months;

Ø The optional time division rate electricity metering function allows for the modification of time period rate parameters through parameter setting software;

Ø RS-485 communication interface with electrical isolation, supporting DL/T645-2007 and Modbus protocol (optional);

Ø 485The default baud rate is 2400bps, which can be modified to 1200-9600 through parameter setting software;
