Tips: Soft starter is better than VFD regarding Harmonics effects
Motor soft starter does help in reducing inrush currents, most soft starters come with an adjustable kick current to overcome the initial inertia needed. Once up to speed it does switch over to being across the power grid. Be careful here if you ever expect to start ATL, the manufacturers generally reduce the size of the bypass contactor. Harmonics are nasty as well running through the SCRs during the start sequence. Variable frequency drives (VFD) come in a variety of front ends from 6-pulse, 12-pulse, 18-pulse, and active front ends. Harmonics are present in all variable speed drives applications so be aware of these and their effects.

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.
