The factory flagship product is characterized by compliance with IEC61558 standard, which makes it suitable for electronic equipment in a highly dense environment. The toroidal transformer has the ability to transmit power with high efficiency and the power / volume ratio is superior to the standard transformers. Due to its structure, the magnetic flux is concentrated in the transformer body and has very small noise effect on the electronic components in its environment. The manufacturing process is according to customer’s specifications for various voltages, frequencies, power rating and specific standards. The transformers are Class B 130ºC and are available with Class H 180ºC insulation system. These transformers are also available with UL Recognized certificates.
