Precautions

Main circuit uses 3-phase 3-wire input, no phase sequence is required.
SCR is high current product, please be sure to lock the (R.S.T) and (U.V.W) terminals, otherwise the terminals will heat up and the SCR will burn out.
SCR has a built-in fast fuse for over current and short circuit protection. If the fuse is blown due to overcurrent, first check the load for faults such as short circuit and partial discharge. After troubleshooting, open the panel and replace it. Be sure to replace it with fuse of the same specification. Be careful not to increase amperage of the fuse at will.
When using the load Y type wiring method, center point cannot be connected to zero line, otherwise the SCR will lose control. If 3-phase load is unbalanced, center point must be connected to zero line.

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.
