    HTB50-P/SP5 Current Sensor – Precision Measurement, Compact and Reliable


    HTB50-P/SP5 Product Overview

    The HTB50-P/SP5 is a high-performance Hall-effect open-loop current sensor from LEM, a world-renowned manufacturer of electrical transducers. Founded in Geneva, Switzerland in 1972, LEM has been focusing on Hall-effect based current sensing and is a global leader in the field.

    The HTB50-P/SP5 is designed for electronic measurement of DC, AC, pulsed, and mixed currents, providing complete electrical isolation between the primary (high power) and secondary (electronic) circuits. It belongs to LEM’s HTB series, which includes seven models with the same compact design. The sensor occupies only 4.3 cm² of PCB area and features a 16 mm diameter aperture.

    HTB50-P/SP5 Key Highlights

    Hall-Effect Open-Loop Technology – Accurate and Reliable

    Using Hall-effect open-loop principle, the output is a voltage signal that faithfully follows the primary current waveform. Accuracy and linearity are both better than ±1%, ensuring true and precise measurement.

    2500V High Electrical Isolation – Safe Operation

    The sensor provides 2500V isolation between primary and secondary circuits, fully separating high-power and low-power sections for safe system operation.

    < 3 µs Fast Response – Capture Transient Currents

    With a response time of less than 3 μs and a bandwidth from DC to 50 kHz, the HTB50-P/SP5 accurately captures fast-changing current signals, meeting the needs of high-performance applications.

    Compact Design – Saves PCB Space

    The sensor has a small footprint of only about 4.3 cm² on a PCB and a height of 34 mm, ideal for space-constrained embedded designs.

    Low Power Consumption – Green and Energy-Efficient

    Consuming less than 15 mA, it is well suited for battery-powered or low-power systems.

    Wide Temperature Range – Performs in Harsh Environments

    Stable operation from -25℃ to +85℃ ensures reliable performance in demanding industrial conditions.

    UL 94-V0 Enclosure – Flame-Retardant and Safe

    The insulated plastic case is UL 94-V0 rated, meeting stringent safety standards.


    HTB50-P/SP5 Typical Applications

    The HTB50-P/SP5 is widely used in industrial, energy, and automation applications, including:

    AC variable speed drives and servo motor drives – accurately monitor motor current for precise control

    Static converters for DC motor drives – ensure stable operation of the converter

    Switched mode power supplies (SMPS) – real-time current monitoring for reliable output

    Uninterruptible power supplies (UPS) – detect input/output current to maintain power continuity

    Battery powered equipment – low power consumption makes it ideal for portable devices

    Power supplies for welding equipment – precisely measure welding current for quality control

    Variable speed drives for home appliances and air conditioners – widely used in consumer electronics


    Why Choose the HTB50-P/SP5?

    Advantage

    Explanation

    Single design covers wide current range

    HTB series spans 50A to 400A with the same footprint, easy to upgrade or substitute

    High immunity to external interference

    Hall-effect open-loop design provides good rejection of external electromagnetic noise

    Easy installation

    50A and 100A versions are available with optional primary busbar for easier connection

    Trusted brand

    LEM has decades of experience in electrical sensing – proven quality and global recognition
