1. It is mainly used for measuring DC voltage, current, active power, frequency and energy consumption
2. The current measure range is 50A, 100A, 200A, 300A on the external shunt specification
3. There are 10 different kits to choose, enough to meet your various need
4. Physical layer use UART to RS485 communication interface, baud rate is 9600, 8 data bits, 2 stop bit, no parity
5. The application layer use the ModbusRTU protocol to communicate, it only supports function codes such as 0x03, 0x04,0x06, 0x41, 0x42, etc

Specification:
This module is mainly used for measuring DC voltage, current, active power, frequency and energy consumption, the module is without display function, the data is read through the RS485 interface.
