FPT Series Power Toroidal Transformers


FPT Series Power Toroidal Transformers offers 44 standard models from 15VA to 500 VA. Dual 115/230V 50/60Hz rated primary and dual secondaries for series or parallel selection with class B 130°C insulation system utilized. Low radiated magnetic field. CSA and UL recognized components LR16597, E105782. Dielectric tested to UL/CSA standards. Custom sizes, ratings and terminations may be engineered for your specific application. ATC-Frost UL / CSA family recognition assures fast, trouble free approval of your equipment. Toroidal transformer designs are typically 50% lighter and much more compact than traditional EI laminated transformers. Custom toroid transformer dimensions may be varied to accommodate alternate dimensional requirements such as low profile or slim line equipment. Low stray magnetic fields compared to traditional EI laminated transformers. Low noise – toroidal construction ensures that mechanical hum” will be minimal.

Aerospace Planar Transformer for Switch-Mode Power Supplies

In this Planar Transformer mini case study, we discuss how we partnered with an aerospace customer, delivering a coupled hybrid aerospace solution that integrated a standard planar transformer with an inductor. We solved the customer's challenge of decreasing unit costs while saving design space and improving overall performance with the added benefit of reducing electromagnetic interference (EMI).

A planar transformer, the primary component used in switch-mode power supplies, offers volumetric efficiency and a lower profile over traditional wire-wound transformers because it uses printed circuit boards (PCB) for its turns.
