PEACEFAIR PZEM-003 DC Voltage Current Power Energy Cons

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.

Feature:
It is mainly used for measuring DC voltage, cur
rent, active power, frequency and energy consumption.
Comes with built in shunt, the current measure range is 0.01-10A.
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 v
oltage and low voltage threshold, when the measured voltage exceeds the threshold, it can alarm.

1 x RS485 to USB Cable
Note:
RS485 interface is passive ou
tput, need external connect 5V power supply and the external power supply should ＞100mA.
When the input test voltage is less than 7V, it must supply 5V independent work voltage through USB port.
Do NOT use the USB port bring b
y your PC to be the independent power supply, otherwise it may damage your PC.
