PMK LILCO current probe 13E0200 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 makes it suitable for high-transient-current measurements such as large-scale scientific electromagnetic pulses, EMC, pulse currents, and surge currents.

The 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 measurement 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 influence 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 setups where unwanted current (e.g., ground loops) occurs between input and output.

The BNC output of the LILCO® series current transformers makes it easy to connect to various measurement devices with only a 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 measurement instrument, low-frequency performance and I·t capability can be improved, and the output signal can be attenuated. The LILCO® series ATT10BNCS attenuator 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:

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

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

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