Minuzzi transformers: history, technology and models

Minuzzi has worked since 1982 in Campinas making transformers and autotransformers; the catalog models are three-phase autotransformers from 20 to 250 kVA, without the galvanic isolation of an isolating transformer.

Company typeBrazilian manufacturer of transformers and autotransformers

Transformadores Minuzzi was founded in 1982 in Campinas and reports more than four decades in the electrical sector, with national development and manufacturing.

Its portfolio separates three-phase isolating transformers, ATF autotransformers and TTS/ATS versions for photovoltaics. The active products in the Silizium catalog are described as three-phase autotransformers; this distinction changes protection, earthing and safety.

  • More than 40 years of manufacturing in Brazil
  • Lines specifically for power electronics and photovoltaics

What to check before buying

An autotransformer does not provide galvanic isolation. Confirm kVA rating, voltages, taps, frequency, vector group, neutral, inrush current, losses, thermal class, impedance and compatibility with the inverter's harmonics.

Buying Minuzzi equipment in Brazil

The equipment must be specified by an engineer and accompanied by a diagram, protections, ventilation, earthing and a record of technical responsibility. Confirm whether the application requires an isolating transformer or accepts an autotransformer, and validate the warranty of the custom code.
