Tips: How to judge the quality of DC contactor?

  • Appearance: Check the DC contactor for abnormal wear, deformation or corrosion.
  • Electrical performance: Use a multimeter or rack test equipment to test the continuity of the circuit and check for damage or open circuits.
  • Mechanical performance: Check the sensitivity, operating force and reset condition of the DC power contactor switch to see if there are any problems that are too large or too small.
  • Insulation performance: Test the DC contactor to check whether there is leakage or load current drop.
  • DC contact material: The material of the contacts determines the service life of the DC power contactor. The cost of really good contacts is relatively high and is made of silver alloy. Some inferior contacts are made of copper alloy, or a layer of silver is electroplated on the copper contacts. Alloys have a very short service life.

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.
