Tips: Characteristics of RDDLZ isolation transformer at the AC power input
- If the third harmonic and interference signal of the Grid is severe, use isolation transformer to remove the third harmonic and reduce the interference signal.
- The use of isolation transformers can generate a new neutral line to avoid the abnormal operation of equipment caused by unfit neutral power line.
- The current waveform distortion(such as third harmonic) caused by nonlinear load can be isolated without affecting the Grid.
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.
