描述

AttoPilot Voltage and Current Sense Breakout – 45A 電壓和電流檢測感測模組 美國 SparkFun 原裝進口

這是一個小電壓和電流感應PCB。直流電流通過測量一對並聯分流電阻上的壓降來確定,然後由TI INA-169轉換為最終的模擬電壓輸出。電壓檢測通過精密電阻分壓器縮放至3.3V ADC範圍來實現。

規格與特色

  • 輸入電阻分壓比例為13.6V輸入電壓(推薦)
  • 最大51.8V
  • 最大44.7A
  • 極低的零電流偏移
  • 模擬電流輸出按比例調整為3.3V ADC
  • 自供電
  • 4 x 15 x 19毫米

原廠技術文件與範例

AttoPilot Voltage and Current Sense Breakout – 45A

This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel shunt resistors, then converted to a final analog voltage output by the TI INA-169. Voltage sense is accomplished by scaling to 3.3V ADC range by a precision resistor divider. The PCB is supplied without leads or connectors. The pad sizes are large enough to accommodate 12 gauge heavy duty leads (see datasheet) but care must be exercised in soldering. Smaller gauge leads are considerably easier to solder without creating shorts.

FEATURES

  • Input resistor divider scaled for 13.6V Input voltage (recommended)
  • 51.8V Max
  • 44.7A Max
  • Very low zero current offset
  • Analog current output scaled for 3.3V ADC
  • Self Powered
  • 4 x 15 x 19mm
