An absorbing clamp is used for the measurement of interference signals on a power supply cable. Both models meet the CISPR 14 (EN 55014) standard for the measurement of interference of household appliances, electrical tools, and similar apparatus.
The absorbing clamps measure radio noise power of the power cables which are fed through them. Consisting of a calibrated ferrite current transformer and two groups of ferrite rings and operate in a frequency range of 30 MHz - 1 GHz. The ferrite rings absorb the energy that comes through, and stabilize the impedance level.
One set of ferrite rings surrounds the lead from the transformer to the EMI meter for minimizing standing waves. The second group of ferrite rings surrounds the supply cables from the equipment under test (EuT). These rings act as an absorber of energy and an impedance stabilizer to isolate the equipment under test from the external power source. These rings are made up of two halves, which makes it easy to place the power cable from the EuT inside the clamp rings.
Before shipping each individual absorbing clamp is carefully calibrated with equipment approved by the National Institute of Standards and Technology (NIST). Data and certificate of calibration are shipped with the product.Features:
We offer two models to accommodate for a variety of power cable sizes. The CLA-050 model can accommodate power cables up to 10 mm (0.39 inches) in diameter. The CLA-150 model can fit cables up to 32 mm (1.26 inches) in diameter.
|CLA-050||10 mm / 0.39 inches|
