AttoPilot Voltage and Current Sense Breakout – 180A

描述

AttoPilot Voltage and Current Sense Breakout – 180A 美國 SparkFun 原裝進口

這是一個小電壓和電流感應PCB。直流電流是通過測量一對並聯的1 mOhm分流電阻上的壓降來確定的，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。

PCB不帶引線或連接器。焊盤的尺寸足夠大，可以容納12號的重載導線（見數據表），但必須小心焊接。較小的儀表引線相當容易焊接而不會造成短路。

規格與特色

• 最大51.8V
• 最大89.4A
• 極低的零電流偏移
• 模擬輸出按比例調整為3.3V ADC
• 自供電
• 4 x 15 x 19毫米

AttoPilot Voltage and Current Sense Breakout – 180A

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.
