Tips: The difference between no-load and load transformer

The main difference between no-load operation and load operation of the transformer is mainly reflected in the secondary line state. The secondary line of the transformer load operation is connected to the load, and the generated power is large.

The transformer uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for voltage rise and fall, impedance matching, and safety isolation. When the transformer is running at no load; only no-load loss, that is, iron loss and stray, is consumed, which is 6% of the total capacity, and when the load is running, it is no-load loss + load loss, that is, copper loss, which is the total consumption of the transformer.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
