Máy kiểm tra điện Pzem-003 Dc 0-300V với điện áp Modbus Rs485 và máy đo dòng điện có độ chính xác cao Kilowatt-giờ [B/5]

Features: 1. This module is mainly used to measure DC voltage, current, active power, frequency and energy consumption. The module has no display function, and the data is read through the RS485 interface. 2. The RS485 interface is a passive output, which requires an external 5V power supply, and the external power supply should be greater than 100mA. = 3. The physical layer uses UART to RS485 communication interface, the baud rate is 9600, 8 data bits, 2 stop bits, and no parity. 4. Durable material: This product is made of high-quality materials, durable, long service life, firm and stable in use. 5. The voltage threshold can be set, divided into high voltage threshold and low voltage threshold. When the measured voltage exceeds the threshold, an alarm will be issued. High precision, good compatibility and wide application range. Description: This module is mainly used to measure AC voltage, current, active power, frequency, power factor and active energy. The module has no display function, and the data is read through the RS485 interface. Specifications: model: PZEM-003 Voltage measurement range: 0.05-300V Current measurement range: 0.01-10A Power measurement range: 0.1-3kW Measurement accuracy: 1% Package Included: 1 * Voltmeter (without battery) Notes: 1. Please allow 0-1 inch error due to manual measurement. Thanks for your understanding. 2.
