Note:

When the load is a resistive load, the maximum load current of the selected SSR should be 2~3 times greater than the actual load current;
When the load is an inductive load, the maximum load current of the selected SSR should be more than 7~8 times the actual load current.
When the maximum load current is higher than 10A, a heat sink must be installed to the solid state relay, or the SSR relay should be mounted on a metal base plate with heat dissipation effect, and the thermal grease is applied between them.

Tips: Solid state relay has advantages over EMR relay

Solid state relay (SSR) is a new type of non-contact switch composed of solid state electronic components, and achieve the purpose of connecting and disconnecting circuits without contact and sparking by virtue of those electronic components (such as switching transistors, triacs and other semiconductor components). Therefore, it is also known as non-contact switch.

Compared with the previous Electromechanical Relay (EMR), the SSR has no moving mechanical parts and no mechanical actions during its operation. It has advantages over EMR, such as fast response, high reliability, long life (SSR’s on-off times are a hundred time more than those of average EMR by 106 times), no noises, shock-proof, mechanical shock resistance, good moisture-proof and mildew-proof, anti-corrosion characteristics. These features make SSR widely used in military science, chemical industry as well as various industrial and civil electric control devices.

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.
