Tips: Variable Frequency Drive vs Soft Starter
Conventional soft starters control AC motor in soft starting by reduced voltage during starting period. But it also causes a significant reduction in starting torque which will prolong acceleration times. Reduction in mechanical stress is achieved at the expense of increase in electrical stresses. Variable frequency drive (VFD) applies V/Hz method for AC motor speed control to make the motor starting from zero speed to required speed “slowly” (can be set as short as 1s according to practical application demand), and maintain a constant torque in the starting period. Therefore, the VFD controls the motor accelerating smoother than soft starter with lesser electrical stresses. This is especially important in the applications where need high starting torques.

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.
