In industrial automation and power electronics systems, the accuracy and reliability of current measurement directly affect overall system performance and safety. The HX 10-P/SP2 current sensor from LEM, a global leader in electrical measurement technology, provides you with a precise, stable, and easy-to-integrate current sensing solution.

HX10-P/SP2 Product Overview

The HX 10-P/SP2 is a high-performance current sensor based on open-loop Hall effect principle, specifically designed for electronic measurement of DC, AC, pulsed, and mixed currents. It provides galvanic isolation between the primary (high-power side) and secondary (electronic circuit side), ensuring both measurement accuracy and system safety. With a rated current of 10 A and a measuring range up to 30 A, it adopts a compact PCB-mount design, making it an ideal choice for current monitoring in various industrial equipment and power supply systems.

HX10-P/SP2 Key Advantages

Precise Measurement, Reliable Operation
Linear accuracy and precision reach ±1%, with a response time of only 3 µs and a frequency bandwidth of DC to 50 kHz. The sensor captures fast-changing current signals, ensuring every reading is accurate.

Wide Operating Temperature, Strong Environmental Adaptability
Operating temperature range covers -25°C to +85°C, suitable for various industrial environments from severe cold to high heat – whether outdoor substations or high-temperature equipment rooms, it performs reliably.

Galvanic Isolation for Enhanced Safety
Galvanic isolation test voltage of 3000 V between primary and secondary, plus a UL94-V0 rated flame-retardant housing, provides a reliable safety barrier in high-voltage applications.

Compact Design, Easy to Integrate
Weighing only 8 grams and requiring just 2.93 cm² of PCB mounting area, its small footprint offers great design flexibility for space-constrained equipment. Through-hole mounting supports automated assembly, significantly improving production efficiency.

Low Insertion Loss
Minimal impact on the measured circuit, ensuring system performance remains unaffected.

Wide Supply Voltage Compatibility
Supports ±12 V to ±15 V dual power supply as well as +12 V to +15 V single power supply, meeting different system power architecture requirements.
