LEM HX25-P
HX25-P
The HX25-P by LEM is a precise current transducer for measuring AC, DC, and pulsed currents up to 25 A RMS, with a peak range of 75 A. Using open-loop Hall effect technology, it provides galvanic isolation between the primary and secondary circuits. The device operates with a dual supply voltage of ±12V to ±15V and has a compact footprint suitable for PCB integration.
The HX25-P is designed for stable performance in electrically noisy environments, with low power consumption and an extended measuring range up to three times the nominal current. Its insulation voltage of 3000 V and plastic casing rated UL94-V0 support long-term reliability and compliance with safety standards.
This transducer is suitable for various industrial and commercial applications, including Switched Mode Power Supplies (SMPS), AC variable speed drives, Uninterruptible Power Supplies (UPS), battery-powered systems, and DC motor drives. Its combination of accuracy and compact size makes it suitable for systems requiring reliable current measurement.
