Tech Power Electronics announces the release of three new nanocrystalline current sense transformers SCTN20, SCTN30, SCTN70. They are designed for power electronic applications which require a highly-accurate current measurement.
In comparison with other soft magnetic materials, nanocrystalline alloys is the best material to be used in toroidal core for current transformers, due to its high magnetic permeability and low core losses. Furthermore current sense transformers made with nanocrystalline cores offer a reduced size and weight, as well as a larger operating temperature range from -40 to 125°C.
Its range of nanocrystalline current sense transformers is designed for a 50 – 400 Hz frequency range with a 0.2 or 0.5 accuracy class. They are available for rated currents 10A, 12A, 20A, 30A and 70A. All models are RoHS and Reach compliant. They are housed in a plastic package using UL94 V-0 materials.
