DC Communication Box, DC Current Voltage Power Energy Frequency Module Meter with RS485 USB Interface

DC Communication Box, DC Current Voltage Power Energy Frequency Power Factor Communication Module Meter with RS485 USB Interface, High Precision Ammeter Voltmeter Multimeter(50A)

DC Communication Box, DC Current Voltage Power Energy Frequency Module Meter with RS485 USB Interface

Features: It is mainly used for measuring DC voltage, current, active power, frequency and energy consumption. The current measure range is 50A, 100A, 200A, 300A depend 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. Specification: Brand: PEACEFAIR Model: PZEM-017 Voltage: Measuring Range: 0.05-300V (When the test voltage is 7V, please use the independent power supply mode) Resolution: 0.01V Measurement Accuracy: 1% Current: Measuring Range: 0.02-300A (Can be matched with 50A, 100A, 200A, 300A four kinds of shunt) Resolution: 0.01A Measurement Accuracy: 1% Power: Measuring Range: 0.2-90kW Resolution: 0.1W Measurement Accuracy: 1% Energy Consumption: Measuring Range: 0-9999kWh Resolution: 1Wh Measurement Accuracy: 1% Reset Energy: Use Software to Reset Over Voltage Alarm: Default High Voltage Threshold: 300V Default Low Voltage Threshold: 7V Communication Interface: RS485 Interface Working Temperature: -20~60 Product Size: Approx. 9*6*2.3cm/3.5*2.4*0.9inch Weight: Approx. 77g~287g / 2.7oz~10.1oz

• ✅ MEASUREMENT PARAMETERS Multi-function meter can measure DC voltage, current, active power, frequency and energy consumption. The voltage measurement range is 0.05-300V (When the test voltage is 7V, please use the independent power supply mode) The current measuring range: 0.02-300A (Can be matched with 50A, 100A, 200A, 300A four kinds of shunt) The power measurement range is 0.2-90kW The energy consumption measuring range is 0-9999kWh.
• ✅ ALARM INDICATION Alarm indication: over power alarm: active power threshold can be set, when the measured active power exceeds the threshold, an alarm can be issued. The overload alarm function not only protects the instrument from being burnt out, but also serves as a safety protection against fire.
• ✅ APPLICATION LAYER PROTOCOL The application layer use the Modbus-RTU protocol to communicate.At present, it only supports function codes such as 0x03 (Read Holding Register), 0x04 (Read Input Register), 0x06 (Write Single Register), 0x41 (Calibration), 0x42 (Reset energy).etc.
• ✅ NOTE RS485 interface is passive output, need external connect 5V power supply and the external power supply should 100mA.When the input test voltage is less than 7V, it must supply 5V independent work voltage through USB port. Do NOT use the USB port bring by your PC to be the independent power supply, otherwise it may damage your PC.,if you have any problem about the product,please feel free to contaut us,we will reply you in 24 hours.
