Custom Transformers

The FF Series is engineered to meet UL/CSA/TUV/IEC standards in medical (IEC601), instrumentation (IEC1010), or audio products (IEC65). Available in toroidal, switch mode, chassis, PC-mounting or SMT formats, their power range is less than 50kW, less than 500 kHz operating frequency with input(s) or output(s) less than 600V. Products are designed to approved class B (130°C) as or class H (180°C) insulation systems, with isolation of 4kV or higher between windings.

Powerline Magnetics

Powerline transformers provide enhanced performance required by the standards Homeplug 1.0, EIA 709.2, CEA R7.3, and European CENELEC EN 50065-1. Their outstanding size and cost-optimized designs use advanced magnetic cores and materials. Magnetic cores based on VITROVAC and VITROPERM alloys yield superior electrical performance over the spectrum of transmitted frequencies. Their compact design is accomplished by exploiting the highest saturation flux density of the cores.
