    HX25-P Open-Loop Hall Effect Current Sensor

     

    HX25-P Precise Current Detection Empowers Industrial & Energy Applications

    The HX25-P is a high-performance open-loop Hall effect current sensor from LEM, a globally recognized leader in sensor technology. With a nominal current rating of 25A RMS and an extended measuring range up to 75A, it is specifically designed for drives, power supplies, renewable energy, welding, and many other applications. Thanks to its outstanding performance and high reliability, the HX25-P has become the ideal choice for measuring DC, AC, and pulsed currents in industrial environments.

     

    HX25-P Key Advantages

    Galvanic Isolation for Safety & Reliability

    The HX25-P uses the open-loop Hall effect principle, providing 3000V galvanic isolation between the primary and secondary circuits. This effectively protects downstream electronics and operator safety.

    Wide Measuring Range for Versatile Operation

    With a nominal current of 25A and an extended measuring range up to 3 times the nominal value (75A) , the HX25-P easily handles momentary overloads and inrush currents.

    Low Power Consumption – Green by Design

    Maximum supply current is only 15mA, making it extremely power-efficient – ideal for battery-powered and energy-sensitive applications.

    Ultra-Fast Response to Capture Transients

    A 3µs fast response time accurately captures rapidly changing current signals, meeting the demands of high-frequency dynamic measurements.

    Compact & Space-Saving Design

    The HX25-P comes in a compact modular package, occupying only about 2.93 cm² of PCB area and weighing only 8g. It is perfect for space-constrained circuit designs. The insulating case meets UL94-V0 flammability rating.

    HX25-P Typical Applications

    With its excellent overall performance, the HX25-P is widely used in:

    Switched-mode power supplies (SMPS) – precise output current detection for closed-loop control and overcurrent protection

    Variable frequency drives – real-time motor current monitoring for improved drive control accuracy

    Uninterruptible power supplies (UPS) – battery charge/discharge current monitoring to ensure power security for critical loads

    Renewable energy systems – current monitoring in photovoltaic inverters, wind power converters, etc.

    DC motor drives – precise speed and torque control

    Welding equipment – real-time welding current monitoring and control
