Transformers for DIN rail mounting are most often used in industrial machine control installations or in circuit status signalling. This is because nowadays the majority of electrical devices required to build such systems favour precisely this method of mounting. As...

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...

What is intermittent duty of a transformer? The rating required for a transformer operating in an “intermittent” manner in identical, defined cycles is determined from the following formula: S = √ (tp/(4tc) x Sodb where: S – transformer rating tp...
