The module does not have a display function, and data is read via the RS485 interface. 2. 【Input Power】The RS485 interface is a passive output, requiring an external 5V power supply with a current draw greater than 100mA. The current measurement range is 50A, 100A, 200A, and 300A, depending on the specifications of the external shunt. 3. 【Various Kits】The physical layer uses the UART communication interface over RS485, with a baud rate of 9600, 8 data bits, 2 stop bits, and no parity. You have a choice of 10 different kits, sufficient to meet your various needs. 4. 【ModbusRTU Protocol】The application layer uses the ModbusRTU protocol for communication; it only supports function codes such as 0x03, 0x04, 0x06, 0x41, 0x42, etc. It can display six measurement parameters on the computer while communicating via software. It can also communicate with the buyer's microcontroller (the buyer must program it themselves). 5. 【Widely Used】The voltage threshold can be set to high and low voltage levels; when the measured voltage exceeds the threshold, it can trigger an alarm. Its high precision and better compatibility will make it widely used.
