A choke is simply an inductor with a magnetic core that prevents sudden changes in the electric current. It can also be used to limit alternating current without the power losses that would occur if the limiting element were a...

A transformer is used to convert an alternating voltage of a given value into an alternating voltage of a different value, while maintaining the same frequency. A special case is that of transformers which do not change the voltage values,...

The basic information on how a transformer works was explained in the previous article. It is worth developing a few further concepts and relationships, however, in order to understand the functionality, operating principles and construction of this type of device...

Questions often arise about isolating transformers. Isolating transformers are those transformers in which the output voltage is most often equal to the input voltage. They provide galvanic isolation between the primary and secondary windings. Isolating transformers are used wherever protection...

One of the key aspects of insulating buildings is cutting the expanded polystyrene correctly. It is essential that the cut boards fit precisely against one another. Mechanical cutting, for example with a saw or a knife, causes large quantities of...

Safety isolating transformers provide, in accordance with standard PN-EN61558-2-6, protective separation of the primary and secondary windings. They are intended to supply circuits with a safety extra-low voltage. Furthermore, the secondary voltage under no-load conditions must not exceed 50V AC...

In response to the needs of our Customers, we have prepared a complete overview of Breve controllers. The overview lists all the functions of our devices and indicates their applications. Selecting the best controller is now easier than ever before....

Electronic controllers allow stepless control of fans. The ARES design from Breve is based on a microprocessor, which makes fan control more linear, more convenient and more precise. The ARES controller is distinguished by: a compact design; a high level...

An autotransformer is a device used to change the voltage level. Its fundamental feature is that it provides no galvanic isolation of the secondary side from the primary side. This is undoubtedly a drawback of such a design, however in...
