Product Type:DC Communication Module

Product Model:PZEM-003/017

Product function:

This document describes the specification of the PZEM-003/017 DC communication module, the module is mainly used for measuring DC voltage, current, active power and energy consumption, the module is without display function, the data is read through the RS485 interface.

PZEM-003: Measuring Range 10A (Built-in Shunt)

PZEM-017: Measuring Range 50A、100A、200A、300A (the current range is depend on the external shunt specification )

 

Measurement range:

  1. Voltage
    1. Measuring range:0.05-300V. (when the test voltage is <7V, please use the independent power supply mode)   
    2. Resolution:0.01V.
    3. Measurement accuracy:1%.
    4. Current
      1. Measuring range:0.01-10A(PZEM-003);0.02-300A(PZEM-017;can be matched with 50、100、200、300A four kinds of shunt).
      2. Resolution:0.01A
      3. Measurement accuracy:1%
    5. Power
      1. Measuring range:0.1-3kW(PZEM-003);0.2-90kW(PZEM-017)
      2. Resolution: 0.1W
      3. Measurement accuracy:1%
  2. Energy Consumption
    1. Measuring range: 0-9999kWh
    2. Resolution: 1Wh
    3. Measurement accuracy:1%
    4. Reset energy: use software to reset.
  3. 1.5 Over Voltage alarm

Voltage threshold can be set, divide into high voltage and low voltage threshold, when the measured voltage exceeds the threshold, it can alarm

The default high voltage threshold is 300V, the default low voltage threshold is 7V.

1.6 Communication interface

RS485 interface.

1.7 Physical layer protocol

Physical layer use UART to RS485 communication interface.

Baud rate is 9600, 8 data bits, 2 stop bit, no parity.
