6 in 1 Battery Monitor Color LCD Screen Meter Coulomb Power Voltage Ammeter Temperature Power Gauge Communication 4 Typ Features: There are 4 standard: 100A/200A/300A/500A, choose based on your needs. Real-time display voltage, current, power, capacity, energy, temperature, operating time,etc. Over-power, over-voltage, under-voltage, over-current and over-temperature protection can be realized through the reserved relay interface. Two-way current detection, detection of charge and discharge users can be very convenient to detect two-way current, without changing the direction of wiring. Memory function of power outage, after power outage can remember the ampere hour (AH) before power outage, convenient observation and measurement. Ampere hour (AH) number one key can be filled or cleared, does not affect the direct charge and discharge measurement. Specifications: Material: Plastic+Metal Diverting table head: approx 42x78x25mm/1.7x3.1x1in Shunt module: approx 49x86mm/2x3.4in 6P- blue and white line length: approx 200mm/8in Packing size: approx 13x8.2x9.2cm/5x3x3.6in Standard: 100A/200A/300A/500A(optional) Can be calibrated online, convenient for customers to correct errors in time. The LCD screen can automatically turn off and light up to reduce product power consumption. Switching voltage & current waveform display function, more intuitive observation of voltage and current change curve. The relay port can be switched to the buzzer port to realize the sound alarm function. Undervoltage capacity can be automatically reset, overvoltage capacity can be automatically filled to facilitate long-term recycling customers, automatic correction error. Package Includes: 1x Battery Monitor Note: Please allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid. Due to the difference between different monitors, the picture may not reflect the actual color of the item.
