KR Sense 45A Current and Voltage Sensor

Description:

This is a small voltage and current sense breakout board. DC current is determined by measuring a voltage drop across a�parallel shunt resistor, 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.

This product is compatible with the Attopilot 45A Voltage and Current Sensor Brakout.

This breakout board is supplied without leads or connectors. The pad sizes are large enough to accommodate 12 gauge heavy duty leads 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) for 3.3V output
• 51.8V Max
• 44.7A Max
• Very low zero current offset
• Analog current output scaled for 3.3V ADC
• Self Powered

Calculations:

Input Voltage can be derived from Vout. Vsource = Vout * 0.2423

Input Current can be derived from Iout. Isource = Iout * 0.0732
