KR Sense Current and Voltage Sensor - 90A



Description Attachments

The KR Sense 90A is a compact voltage and current sense breakout board designed for precision and efficiency. It determines DC current by measuring a voltage drop across a parallel shunt resistor, which is then converted to a final analog voltage output by the INA-169. Voltage sense is achieved by scaling to 3.3V ADC range using a precision resistor divider. This particular model of the sensor can withstand a maximum voltage of 51.8 Volts at 89.4 Amps.

The KR Sense 90A offers a unique advantage in its compact size and high performance, but it's essential to note that the boards are delivered without leads or connectors. The pad sizes are large enough to accommodate 2.05mm heavy-duty leads, but careful soldering is necessary. Using smaller gauge leads can simplify the soldering process and reduce the risk of shorts.

The KR Sense 90A is compatible with the Attopilot 90A Voltage and Current Sensor Breakout, making it a versatile addition to any electronics project.

Key Features:

  • Input resistor divider scaled for 13.6V Input voltage (recommended) for 3.3V output
  • Maximum voltage tolerance of 51.8V
  • Maximum current capacity of 89.4A
  • Exceptionally low zero current offset
  • Analog current output scaled for 3.3V ADC
  • Self-powered for added convenience
