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. Features: It is mainly used for measuring DC voltage, current, active power, frequency and energy consumption. The current measure range is 50A, 100A, 200A, 300A on the external shunt specification. There are 10 different kits to choose, enough to meet your various need. Physical layer use UART to RS485 communication interface, baud rate is 9600, 8 data bits, 2 stop bit, no parity. The application layer use the ModbusRTU protocol to communicate, it only supports function codes such as 0x03, 0x04,0x06, 0x41, 0x42, etc. Voltage threshold can be set, divide into high voltage and low voltage threshold, when the measured voltage exceeds the threshold, it can alarm. Specification: Brand: PEACEFAIR Model: PZEM-017 Voltage: Measuring Range: 0.05-300V (When the test voltage is ＜7V, please use the independent power supply mode) Resolution: 0.01V Measurement Accuracy: 1% C
