The HSTS21 Hall Effect Split Core Current Sensor is a precision measurement device designed for monitoring AC and DC currents in industrial, commercial, and automotive applications. This versatile sensor accommodates a wide input range from 50A to 600A, making it suitable for various electrical systems and power monitoring needs. The split core design is its standout feature, allowing for quick and easy installation around existing conductors without the need to disconnect or interrupt wiring. Simply open the hinged core, place it around the wire, and secure it closed. The sensor outputs a stable 2.5V center voltage with a ±0.625V swing proportional to the measured current, providing a clear analog signal that interfaces easily with microcontrollers, data acquisition systems, and monitoring equipment. Operating on a single +5V DC power supply, the HSTS21 maintains low power consumption while delivering reliable performance. Its compact, robust construction features CE and RoHS certifications, ensuring compliance with international safety and environmental standards. The single-phase configuration makes it ideal for measuring current in individual conductors. Whether you're building an energy monitoring system, protecting electrical equipment, or developing smart power management solutions, this Hall Effect current sensor delivers accurate, non-invasive current measurement in a user-friendly package.
