PEACE Voltage Meter PZEM-017 DC Voltage Meter with Modbusrtu Protocol for Power Management (PZEM-017 - 50A - USB)

1. It is mainly used to measure DC voltage, current, active performance, frequency, and power consumption. 2. The current measurement range is 50A, 100A, 200A, and 300A. 3. There are 10 different kits to choose from, sufficient to meet your various needs. 4. It uses the physical layer for the communication interface, with a baud rate of 9600, 8 data bits, 2 stop bits, and no parity. 5. The application layer uses the Modbusrtu protocol for communication. It only supports function codes such as 0x03, 0x04, 0x06, 0x41, 0x42, etc. Technical Specification: This module is mainly used to measure DC voltage, current, active performance, frequency, and power consumption. The module has no display function; data is read through the interface. Features: It is primarily used to measure DC voltage, current, active performance, frequency, and power consumption. The current measurement range is 50A, 100A, 200A, and 300A, based on external shunt technical specifications. There are 10 different kits to choose from, sufficient to meet your various needs. It uses the physical layer for communication, with a baud rate of 9600, 8 data bits, 2 stop bits, and no parity. The Modbus protocol uses the application layer for communication. It only supports function codes such as 0x03, 0x04, 0x06, 0x41, 0x42, etc. The voltage threshold can be adjusted, divided into high and low voltage thresholds; if the measured voltage exceeds the threshold, an alert can be triggered.

Note: The interface is a passive output, requiring external connections with a 5V power supply. The external power supply must be >100mA. If the input test voltage is less than 7V, an independent working voltage of 5V must be provided via the USB connection. Do not use your PC's USB connection as an independent power supply, otherwise it may damage your PC.
