PMK LILCO current probe 13G1000 precision wideband RF transformer-pulse CT 500 A/60 MHz

The PMK LILCO series precision wideband RF current/pulsed-current sensor CT features excellent droop characteristics; its bandwidth of 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 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 in 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 measuring devices 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 measuring instrument, low-frequency performance and enhanced 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:

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.^®
