KG140F DC 0-120V 400A Battery Monitor With Shunt Coulomb Meter Voltage Current Capacity Bluetooth App

-Shunt-based monitors provide precise measurements of current flow in and out of the battery. Very accurate estimation of the battery's state 2.4-inch color screen, larger and clearer fonts -Automatically identify the current in both charging and discharging directions -Mobile APP can connect to the meter via wireless Bluetooth to view the real-time curve and historical curve of voltage and current and support historical data export -Can upgrade the firmware of the measurement module through a mobile phone APP -Relay signal drive to control relay after configuring it can realize over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, and over-power protection -Shunt and screws are made of pure copper materials -Power consumption in standby mode is very low -Parameters of voltage, current, and temperature can be calibrated by themselves -Display and measurement modules are connected through a 3-meter communication line, and the maximum length can be extended to 30 meters, which is more convenient for installation -The communication protocol is open source, 485 communication is adopted, and secondary development can be carried out on development tools such as serial port assistant. -Suitable for a variety of batteries like lithium batteries, lead-acid batteries, lithium phosphate batteries, etc., as long as the battery is within the voltage measuring range.
