The HXN20-P is a current transducer produced by LEM. It's engineered for the electronic measurement of DC, AC, pulsed, and mixed currents. Like other transducers in the HXN series, it employs a closed-loop (compensated) technology based on a magnetic core. This provides galvanic isolation between the primary circuit (carrying the current being measured) and the secondary circuit (outputting the measurement signal).

Applications:

• Variable Speed Drives: Measuring current in motor control applications for precise torque and speed regulation.
• Power Supplies: Monitoring current levels in both AC-DC and DC-DC power supplies to ensure proper operation and prevent overloads.
• Battery Management Systems: Accurately measuring charge and discharge currents in battery systems to optimize performance and extend battery life.
• Inverters: Providing current feedback for controlling and monitoring inverters used in renewable energy systems and other applications.
• Uninterruptible Power Supplies (UPS): Measuring current in UPS systems to ensure reliable backup power.
• Welding Equipment: Monitoring and controlling current in welding power supplies for consistent weld quality.

Features:

• Closed-Loop (Compensated) Technology: Delivers high accuracy and excellent linearity in current measurement.
• Galvanic Isolation: Provides electrical isolation between the primary and secondary circuits, enhancing safety and preventing ground loops.
• Compact Design: Allows for easy integration into space-constrained applications.
• Fast Response Time: Enables accurate measurement of rapidly changing currents.
• Wide Frequency Bandwidth: Suitable for measuring a wide range of current frequencies.
• Low Temperature Drift: Ensures stable and reliable performance over a wide temperature range.

Additional Details:

The HXN20-P typically requires a dual power supply (e.g., ±15V DC). It has a primary current measurement range of up to ±20 A. The output signal is a current proportional to the measured primary current. For detailed specifications such as accuracy, linearity, response time, operating temperature range, and isolation voltage, consult the manufacturer's datasheet. This transducer is commonly used in industrial and automotive applications where accurate and isolated current measurement is critical.
