Single-Phase Transformers
TEFMA Elettromeccanica in Veggiano designs and manufactures single-phase transformers that operate with a single-phase power supply circuit. They receive power from a single-phase power source, such as that supplied by household outlets.
Usually equipped with two windings, one called "primary" and the other "secondary," single-phase transformers play a crucial role in power distribution. The primary winding is connected to the single-phase power source and receives the input voltage, while the secondary winding provides the transformed voltage at the output to power connected devices. Widely used in various applications, including electronic equipment, power supplies, control devices, and electric lighting, single-phase transformers are available in different sizes, power ratings, and configurations to suit specific application needs. Contact us to discover all possible configurations and find the ideal solution for your project.
