Tips: Linear DC Power Supply vs. Switching DC Power Supply

Feature	Linear DC Power Supply	Switching DC Power Supply
Working Principle	Regulates voltage using linear regulators that dissipate excess voltage as heat to maintain a steady output	Uses high-frequency switching and energy storage components (like inductors or capacitors) to regulate voltage efficiently
Efficiency	Low efficiency, as excess energy is lost as heat during regulation	High efficiency, typically 80-90%, as less energy is wasted as heat
Heat Generation	Generates significant heat due to voltage drop in linear regulators	Generates minimal heat due to higher efficiency
Size and Weight	Larger and heavier, especially at higher power levels	Smaller and lighter due to compact design and use of high-frequency switching
Output Noise	Very low noise, ideal for sensitive electronics	Higher noise, which may require additional filtering for sensitive applications
Cost	Generally more expensive due to components and simpler design	Typically less expensive, as fewer and less complex components are required
Applications	Linear DC power supply is ideal for low-power, precision applications like audio equipment, test equipment, and instrumentation	Switching power supply is suitable for high-power applications like computers, LED drivers, and power supplies for industrial systems
Design Complexity	Simpler design with fewer components	More complex design involves switching elements and filtering components

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.
