About this item

The 45 A KR Sense Current & Voltage Sensor Breakout is a compact, self‑powered module that accurately measures DC current and voltage. It uses a heavy-duty shunt resistor to detect currents up to 44.7 A (max 51.8 V) and converts this to an analog voltage via an INA‑169 amplifier. Voltage is scaled down by a precision resistor divider to suit a 3.3 V ADC range, optimized for around 13.6 V input. The design features very low zero‑current offset, making it suitable for sensitive measurements. Supplied without connectors, it supports heavy-gauge wiring and is perfect for automotive, battery-monitoring, and power management applications.
