PMK LILCO current probe 13E0100 precision wideband RF transformer-pulse CT 5000 A/25 MHz

PMK LILCO series precision wideband RF current/pulse current sensor CT, with excellent droop characteristics; bandwidth up to 60 MHz can accommodate 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 transformers can accurately measure large pulsed 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 enables the LILCO® series to be used in measurement setups with large potential differences, or 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 instruments, such as oscilloscopes, digitizers, network analyzers, spectrum analyzers, power analyzers, and digital multimeters, using only a standard 50 Ω coaxial cable.

By changing the input termination of the measurement instrument, low-frequency performance and enhanced 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 inner diameter (in cm) is included in each LILCO® series model number:

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