KG-140F 400A Multifunction Power Indicator Voltage Ammeter Power Display Battery Coulometer Product Selling Points 1: 2.4 inch colour screen, bigger and clearer font, beautiful appearance 2：Automatically identify the current in both directions of charging and discharging. 3: Adopting current*working time to calculate the capacity of charging and discharging, which is more accurate than calculating the remaining power through voltage. 4: Mobile phone APP can connect to the meter through wireless Bluetooth to view data and set parameters. 5：Mobile phone APP can upgrade the firmware of measurement module. 6: Mobile APP can view the real-time curve and historical curve of voltage and current, and support the export of historical data. 7：Shunt and screws are all made of pure copper, the power consumption is very low in standby mode. 8：Configuration of the relay can achieve over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, over-power protection (the delivery list does not contain relays) 9: Voltage, current and temperature parameters can be self-calibrated. 10: The display and measurement module are connected by 3 metres telephone line, and the maximum length can be extended to 30 metres, which is more convenient for installation. KG-F series colour screen wireless for bluetooth battery coulometer is a professional monitoring battery power meter, at the same time can monitor the battery in the charging and discharging process of voltage, current, power, ambient temperature, electrical energy, real-time display of how long the battery can be fully charged, how long the remaining battery power can still be used, KG110F measuring current range is 0-100A, KG140F measuring current range is 0 KG110F measuring current range is 0-100A, KG140F measuring current range is 0-400A, KG160F measuring current range is 0-600A, for the full state voltage 0-120V, lithium batteries, lithium iron batteries and other batteries can be used. Voltage measurement range (external power supply): 0-120V Voltage measurement range (self-powered): 10-120V Voltage resolution:0.01V Current Measurement Range:0~400A Current resolution:0.01A Relay: No relay provided, need to configure your own List 1*Display module 1*Measurement module 1*Sampler 1*Temperature sensor 1*3P green terminal block 1*3 metre communication cable 1*3P cable 1*4P cable _x000D_
