Low-profile transformers

Produzione di trasformatori a basso profilo

Low-profile transformers for printed circuits are electrical transformers that operate in alternating current and are utilised to transfer electrical power from one voltage level to another. The transformers are comprised of a magnetic core and at least two electric coils. The coils are classified according to the number of turns, those with high voltage (HV) with a greater number of turns (with fewer sections) and those with low voltage (LV) with a lesser number of turns (with fewer sections). S.V.T.I. low-profile transformers are designed and manufactured with high-quality materials, copper electrolytic conductor wire, insulators with elevated dielectric and thermal properties (classes F and H), robust and secure mechanical support elements suitable for any installation requirement.


These transformers are designed for safety applications and cover a wide range of powers. The principal characteristics of the low-profile transformers are their small size, high reliability and elevated performance, unique for their optimum degree of insulation between the primary and secondary. The standard version of the low-profile transformers provides for impregnation with self-extinguishing epoxy resin, class F insulation and protection level ideal for electrical equipment in Class II.

Upon request, thermal protection against overheating may also be applied on the primary winding, heating that can be automatically or manually reset, depending on the required applications.


The quality of S.V.T.I. electric transformers is verified across various levels: each implementation phase is checked, from the initial winding to the final test of the transformer itself. Upon conclusion of production, each transformer is tested 100%. In this way, the electromagnetic performance and safety degree is certified for each transformer. The pre-testing and final testing is carried out in accordance with applicable CEI EN 61558 - CEI 96.7 - 96.8 - CE regulations, according to the type of transformer and its utilisation.


The careful overseeing of production processes and customisation of testing with dedicated and specially-designed equipment guarantees maximum reliability for S.V.T.I. electrical transformers.

Also to note is that S.V.T.I. electrical transformers are made with automated machinery to ensure maximum reliability and repeatability of the electric tolerance parameters.


S.V.T.I. designs and develops different types of transformers, projected and customised according to the needs of the end client by maximising performance and preventing any kind of problem. S.V.T.I. low-profile transformers cover a wide range of applications with dimensional and technical characteristics that stretch from standard to more complex customisation.

S.V.T.I. supports its clients throughout the design and customisation of the single-phase transformers and single-phase autotransformers, so as to guarantee the best results in economic and technical performance terms. Precise and binding tests ensure a high degree of safety and reliability for each transformer produced, in accordance with current national and international regulations.
