Tips: How do I protect my circuits from overvoltage when using a variable DC power supply?

To protect circuits from overvoltage when using a variable DC power supply, employ a voltage regulator or a crowbar circuit. A voltage regulator maintains a stable output voltage, preventing it from exceeding a predetermined level. Adjustable voltage regulators like LM317 allow you to set the desired output. Alternatively, a crowbar circuit involves a zener diode and a thyristor. The zener diode monitors voltage; when it exceeds a threshold, it triggers the thyristor to short the circuit, blowing a fuse or triggering a circuit breaker. Properly sized fuses and transient voltage suppressors can offer additional protection. Regularly check and calibrate your equipment, and consider using an overvoltage protection module. These measures safeguard your circuits against potential damage due to fluctuations in the variable DC power supply.

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.
