High-precision wide-band current transformers for galvanically isolated AC current measurement from sub-Hz to 60 MHz, with ultra-low droop and high I·t capability up to 24 A·s..
The LILCO® Series by PMK offers ultra-precise, galvanically isolated current measurements across a wide frequency spectrum—ideal for power electronics, EMC testing, pulse measurements, and other demanding lab environments.
With a bandwidth ranging from 0.004 Hz to over 60 MHz, the LILCO® series supports everything from ultra-low frequency monitoring to RF current analysis. Its exceptionally low droop characteristics enable long-duration pulse integrity, while its high DC saturation threshold ensures minimal distortion even under intense current loads.
Each model provides BNC connectivity, making it directly compatible with oscilloscopes, digitizers, power analyzers, and other standard test equipment using a 50 Ω coaxial cable.
For setups involving large ground potential differences or risk of ground loops, LILCO® provides complete galvanic isolation between input and output, improving measurement reliability and safety.
With models supporting up to 25 kA current, customizable form factors, and optional accessories like the ATT10BNCS attenuator, LILCO® transformers ensure top-tier measurement performance across multiple industries.
All models come with a factory calibration certificate and a comprehensive user manual that offers guidance on maximizing measurement accuracy.
