PEACEFAIR PZEM017 DC Voltage Current Power Energy Consumption Meter Communication Module (#7)

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 use d for measuring DC voltage, current, active power, frequency and energy consumption. The current measure range is 50A, 100A, 200A, 300A depend 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: PZEM017 Voltage: Measuri ng Range: 0.05300V (When the test voltage is less than 7V, please use the independent power supply mode) Resolution: 0.01V Measuremen t Accuracy: 1percent Current: Measuring Ran ge: 0.02300A (Can be matched with 50A, 100A, 200A, 300A four kinds of shunt) Resolution: 0.01A Measurement Acc uracy: 1percent Power: Measuring Ran ge: 0.290kW Resolution: 0.1W Measurement A ccuracy: 1percent Energy Consumption: Measuring Range: 09999kWh Resolution: 1Wh Measurement Accura cy: 1percent Reset Energy: Use Software to Reset Over Voltage Alarm: Default High Voltage Th reshold: 300V Default Low Voltage Thr eshold: 7V Communication Interface: RS485 Interface Working Temperature: 20~60 celsius Product Size: Approx. 9*6*2.3cm3.5*2.4*0.9inch Weight: Approx. 77g~287g 2.7oz~10.1oz Register address Description Resolution 0x0000 Voltage value 1LSB correspond to 0.01V 0x0001 Current value 1LSB correspond to 0.01A 0x0002 Power value low 16 bits 1LSB correspond to 0.1W 0x0003 Power value high 16 bits 0x0004 Energy value low 16 bits 1LSB correspond to 1Wh 0x0005 Energy value high 16 bits 0x0006 High voltage alarm status 0xFFFF is alarm,0x0000 is not alarm 0x0007 Low voltage alarm status 0xFFFF is alarm,0x0000 is not alarm Register address Description Resolution 0x0000 High voltage alarm threshold(5~350V), default is 300V 1LSB correspond to 0.01V 0x0001 Low voltage alarm threshold(1~350V), default is 7V 1LSB correspond to 0.01V 0x0002 ModbusRTU address The range is 0x0001~0x00F7 0x0003 The current range 0x0000: 100A 0x0001: 50A 0x0002: 200A 0x0003: 300A Optional Kit #1 1 x DC Consumption Meter #2 1 x DC Consumption Meter 1 x RS485 to USB Cable #3 1 x DC Consumption Meter 1 x 50A Shunt #4 1 x DC Consumption Meter 1 x 100A Shunt #5 1 x DC Consumption Meter 1 x 200A Shunt #6 1 x DC Consumption Meter 1 x 300A Shunt #7 1 x DC Consumption Meter 1 x RS485 to USB Cable 1 x 50A Shunt #8 1 x DC Consumption Meter 1 x RS485 to USB Cable 1 x 100A Shunt #9 1 x DC Consumption Meter 1 x RS485 to USB Cable 1 x 200A Shunt #10 1 x DC Consumption Meter 1 x RS485 to USB Cable 1 x 300A Shunt Note: RS485 interface i s passive output, need external connect 5V power supply and the external power supply should more than 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 by your PC to be the independent power supply, otherwise it may damage your PC.
