Voltage transformers
The voltage transformer is a device used to convert, change or adjust the voltages supplied to its primary winding to other lower output voltage values in its secondary winding.
Thanks to their high precision and accuracy, these transformers perform a very important function when monitoring parameters in unstable circuits.
There are two types of transformers: measuring and protection.
According to their applications:
- They can be low voltage transformers, which are used to reduce the voltage of power supplies or for safety functions.
- Measuring and protection transformers, used to reduce voltage or current levels so that they can be measured with conventional voltmeters and ammeters or to protect against excessive current or voltage.
Step-up/step-down transformers:
They can change the magnitude of the alternating voltage (the current does not match the power), increasing or decreasing it. They are often used in electrical and electronic systems, such as those in household appliances and computers. Therefore, they are used to adapt the voltages to those in use.
Variable transformers:
Variable transformers, unlike fixed transformers, allow any specific voltage to be supplied and easily changed when necessary. Using the same iron core, we can obtain different voltages by using different additional secondary coils. Our variable transformers are ruggedly built and come in a wide variety of sizes with different values.
Transformers also have the ability to produce higher output voltages than their input voltages.

The most common applications are:
- Power transformers.
- Distribution transformers.
- Autotransformers
- Voltage regulators.
- Protection relays.
Main sectors:
- Industrial sector.
- Electrical Industry.
- Steel and metallurgical industry.
- Construction
