Three phase open loop current sensor Amphenol HCSP-3BS-0900 with analog output voltage and galvanic isolation
Product Overview
The Piher Sensing Systems HCSP-3BS is a three-phase open-loop current sensor designed for accurate measurement of AC and DC currents. Utilizing Hall effect technology, it provides a ratiometric analog output voltage signal proportional to the current flowing through the conductor. This non-intrusive sensor offers galvanic separation between power and control, ensuring compatibility with Infineon HybridPack. Ideal for automotive battery management and motor control applications, including EV motor inverters and DC/DC converters, it features press-fit contacts for solderless integration and an operating temperature range of -40C to +125C.
