Product Overview
The LEM HC5F300-S is an open-loop automotive current transducer designed for the electronic measurement of DC, AC, or pulsed currents in high-power, low-voltage automotive applications. It provides galvanic isolation between the primary and secondary circuits. The transducer utilizes the Hall effect and offers a choice of peak currents within a single housing, making it suitable for applications such as Electrical Power Steering, Starter Generators, and Converters. Key advantages include good accuracy, linearity, and low thermal drift.
