A new family of transformers

A new family

Planar power transformers

Twenty years ago, Sirio leveraged its expertise in transformer design and manufacturing to create a family of high-frequency power transformers. After months of research and laboratory testing, we are ready to launch our new series of low-profile power transformers. The new planar line offers new options for specific applications requiring compactness, efficient cooling, and higher operating frequencies. The traditional family remains fully available and supported, while new products focus on specific requirements, covering additional applications.

Our 10 kW planar transformer is the first of the new series, designed to set the standard for high performance, compact design, and long-term reliability. Developed and tested in-house with extensive laboratory validation.

A new laboratory for research

since 2023

A new laboratory for research and innovation

Great news in 2023 at Sirio Elettronica: a new research laboratory is already up and running at the production complex via Volta 2.

Lab area: approx. 150 m2.

Our purpose is researching innovative types of transformers that will be used in high frequency converters. The new concept should, at the same time, offer higher efficiency and reduce manufacturing costs through new fully-automated production systems. Currently, the laboratory equipments allow to test new prototypes operating in switch mode converters up to 250 kHz, power rating of 15 kW.

Furthermore, our intention is to extend the power of the converters up to 50 kW.

Sirio 3: new production site

2020: Sirio 3

Sirio 3 plant has been completed: the new production complex is located in via Volta 2, Bresseo di Teolo (Pd), next to the production site of Sirio 2.

Sirio 3 is a three-floored building. The ground floor, where a brand-new vacuum casting system has been recently installed, is used for manufacturing and for all finished goods warehouse: all shipments take place now from the new stock department.

The second floor is completely dedicated to the Final Inspections department in which Sirio components are 100% tested.

The first floor is ready to set-up new production lines.

Move of Sirio India to Moti Nagar

Starting from January 2020, Sirio India has moved to the production site, located in the industrial area of Moti Nagar (New Delhi), tripling its previous production area. The machines and plants were either renewed or replaced.

Such investments have led to an increase of the production efficiency and to a higher product quality.

Impregnation with vacuum and pressure

In order to improve the impregnation process of components, the company has implemented a vacuum casting plant with a pressure autoclave.

After impregnation, the componentsare now placed in a high pressure chamber in order to improve the penetration of the casting compound inside the windings.
