RS485 ModbusRTU DC Power Meter | Precision Machined DC Energy Monitor Module for Voltage Current Consumption with 50A 100A 200A 300A Shunt (PZEM-017)
- Flexible RS485 Modbus-RTU Communication: Features a UART to RS485 interface (9600 baud) using Modbus-RTU protocol (function codes 0x03, 0x04, etc.) for easy integration into monitoring systems, SCADA, or data logging setups.; Comprehensive DC Power Monitoring: Accurately measures DC voltage (0.05-300V), current (0.02-300A with shunt), active power (0.2-90kW), and energy consumption (0-9999kWh) with 1% Precision Machined for precise system analysis.; Multiple Kit Options with Shunts: Choose from 10 different kits, including options with 50A, 100A, 200A, or 300A external shunts and an RS485 to USB cable, to meet various current measurement and connectivity needs.; Programmable Voltage Alarm & Data Registers: Set high and low voltage alarm thresholds via software. Easily read real-time data (voltage, current, power, energy) and device parameters through defined Modbus register addresses.; Compact & Reliable Design: Compact module (approx. 9x6x2.3cm) operates in a wide temperature range (-20~60°C). Note: Requires an external 5V (>100mA) power supply for the RS485 interface; use independent power (not PC USB) when test voltage is below 7V.

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 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.
