LTS25-NP Current Transducer
The LTS25-NP by LEM is a high-performance current transducer designed for accurate and isolated current measurement in power electronics applications. Utilizing closed-loop Hall effect technology, this transducer offers precise monitoring of both AC and DC currents up to ±80A, making it ideal for a wide range of industrial and commercial applications.
With a compact PCB-mountable design and an isolated plastic case recognized according to UL 94-V0, the LTS25-NP ensures durability and reliability in demanding environments. Its excellent accuracy of ±0.2% and linearity error less than 0.1% guarantee precise current measurements, while its wide frequency bandwidth (DC to 200 kHz) and low temperature drift (50 ppm/K) ensure optimal performance across various operating conditions.
The LTS25-NP is widely used in applications such as AC variable speed drives, servo motor drives, static converters for DC motor drives, battery-supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), and power supplies for welding applications. Its bidirectional measurement capability and high immunity to external interference make it a versatile choice for various power electronics systems.
