Working voltage: 0.05 ~300VDC 2. Test voltage: 0.05 ~300VDC 3. Rated power: 10A/3000W 4. Measurement accuracy: 1.0 grade Function and Display format 1 Voltage 1.1 Measuring range:0.05-300V. (when the test voltage is ＜7V, please use the independent power supply mode) 1.2 Resolution:0.01V. 1.3 Measurement accuracy:1%. 2 Current 2.1 Measuring range:0.01-10A(PZEM-003);0.02-300A(PZEM-017;can be matched with 50、100、200、300A four kinds of shunt). 2.2 Resolution:0.01A 2.3 Measurement accuracy:1% 3 Power 3.1 Measuring range:0.1-3kW(PZEM-003);0.2-90kW(PZEM-017) 3.2 Resolution: 0.1W 3.3 Measurement accuracy:1% 4 Energy Consumption 4.1 Measuring range: 0-9999kWh 4.2 Resolution: 1Wh 4.3 Measurement accuracy:1% Reset energy: use software to reset. 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. Communication interface RS485 interface. Communication protocol Physical layer protocol Physical layer use UART to RS485 communication interface. Baud rate is 9600, 8 data bits, 2 stop bit, no parity. Other instructions 1 RS485 interface is passive output, need external connect 5V power supply and the the external power supply should ＞100mA. 2 When the input test voltage is less than 7V, it must supply 5V independent work voltage through MICRO USB port； Note: Do not use the USB port bring by your PC to be the independent power supply, otherwise it may damage your PC ! Working temperature -20’C ~ +60’C 100% new brand high quality 1 x PZEM-003 Module
