PMK LILCO current probe 13 W0200 precision wideband RF transformer-pulse CT 2500 A/30 MHz

PMK LILCO series precision wideband RF current/pulse-current sensor CT, with excellent droop characteristics; a bandwidth up to 60 MHz can accommodate high transient current measurements such as large-scale scientific electromagnetic pulses, EMC, pulse currents, and surge currents.

LILCO® series PMK current transformers have a bandwidth range from mHz to >60 MHz and an input current range from mA to 20 kA, enabling the precision high-bandwidth AC current measurements required for various measurement applications. The current transformer can accurately measure large pulse or continuous input currents, while electrical shielding between input and output reduces the effect of electromagnetic fields on the output.

Galvanic isolation between input and output allows the LILCO® series to be used in measurement setups with large potential differences, or in measurement setups where unwanted currents (such as ground loops) occur between input and output.

The BNC output of the LILCO® series current transformers allows easy connection to various measurement devices with just one standard 50 Ω coaxial cable, such as oscilloscopes, digitizers, network analyzers, spectrum analyzers, power analyzers, digital multimeters, etc.

By changing the input termination of the measuring instrument, low-frequency performance and I·t capability can be improved, and the output signal can be attenuated. The LILCO® series attenuator ATT10BNCS is used to further improve these specifications while maintaining the high-frequency performance of the current transformer.

The LILCO® series inner diameter (in centimeters) is included in each model designation:

For example, 13E1000 = 13mm (0.5''), 26G0100 = 26mm (1.0''), 52GH010 = 52mm (2.0''), 58M1000 = 58mm (2.2''), 89M0100 = 89mm (3.5'')

All LILCO® current transformers are supplied with a factory calibration certificate.

The dedicated instruction manual for the LILCO series contains much valuable information on the general limitations of current transformer use and how to perform accurate measurements, all in a single document.^®
