basic information
The CT6904 series, with its flat frequency characteristics over a wide bandwidth, accurately measures not only the fundamental wave but also the current at the switching frequency. It enables high-quality measurements for the increasingly in-demand SiC and GaN inverters, as well as for loss measurements in reactors and transformers. Its unique shape allows for stable installation and facilitates the shortest wiring for measurement conductors. *Please choose between the "CT6904" with a rated capacity of 500A and the "CT6904-60" with a rated capacity of 800A. *It delivers the best performance when combined with the power analyzer PW6001. Additionally, the "phase correction function" included in the power analyzer PW6001 makes it easy to perform measurements on reactors and transformers with high current, high frequency, and low power factor.
