CT Series

CT series nanocrystalline tape based cores intended for use in electronic wattmeters are manufactured of NANOPERM® made nanocrystalline tape.

High linearity combined with low losses and variable permeability values permit to successfully use nanocrystalline tape based cores for electronic wattmeters (electric energy counters).

  • For household counters according to requirements of IEC 1036 (low permeability, operation with high direct currents)
  • For industrial solutions according to IEC 687

Electromagnetic parameters of Magnetec’s nanocrystalline cores are characterized by a high linearity in wide temperature range and have extremely low value of magnetostriction what excludes possible problems associated with mechanical tensions on winding.

Outer Protective Coating:

  • Epoxy coating (UL-listed Material, File-Nr. E34947)
  • Plastic protective casing (UL-listed Material, File-Nr. QMFZ2 E41938)

It is possible to make cores with dimensions required by Customer.

Low permeability (1.600 < μ < 3.400). For high direct currents.
