Description
 

Description: This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel 1 mOhm 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:

  • 51.8V Max
  • 89.4A Max
  • Very low zero current offset
  • Analog output scaled for 3.3V ADC
  • Self Powered

Dimensions: 4 x 15 x 19mm

Exactly what I ordered.  Soldered Deans connectors straight onto the board.  Works perfectly.  Very happy.

Voltage sensor October 31, 2012
Reviewer: Jean-Sebastien Briere from Parent, QC Canada  
Pour un débutant ou pour un pro, ce sensor est assez facile d'utilisation. Il est très précis et ne demande aucune grande connaissance en électronique pour l'installer a votre APM.
