The HXD25-P is a current transducer manufactured by LEM. It's designed for electronic measurement of DC, AC, pulsed, and mixed currents. The HXD series utilizes a closed-loop (compensated) technology with a magnetic core, providing galvanic isolation between the primary (measured) and secondary (output) circuits.

Applications:

• AC variable speed drives: Measuring the current in motor control applications.
• Static converters for DC motor drives: Monitoring current in DC motor drives.
• Uninterruptible Power Supplies (UPS): Measuring current in UPS systems.
• Welding power supplies: Providing accurate current feedback in welding applications.
• SMPS (Switched Mode Power Supplies): Monitoring current levels in power supplies.
• Battery supplied applications: Measuring charge and discharge currents.

Features:

• Closed-loop (compensated) technology: For high accuracy and linearity.
• Galvanic isolation between primary and secondary circuits: Provides safety and prevents ground loops.
• Low temperature drift: Ensures stable performance over a wide temperature range.
• Wide frequency bandwidth: Capable of measuring a broad range of current frequencies.
• Fast response time: Enables accurate measurement of fast-changing currents.
• Compact design: Suitable for space-constrained applications.
• High immunity to external interference: Provides reliable measurements in noisy environments.

Benefits:

• Accurate current measurement: Enables precise control and monitoring of electrical systems.
