Tips: How to test a rectifier module?

To test a rectifier module, begin by performing a visual inspection to identify any signs of damage, such as burnt components or loose connections. Use a multimeter to check each diode within the module in diode mode, you should observe a forward voltage drop in one direction and no conduction in the reverse direction to confirm proper diode functionality. Additionally, measure the resistance across the input and output terminals to ensure there are no short circuits or unexpected low resistance readings.

Next, connect the rectifier module to an AC power supply and use the multimeter to measure the DC output voltage. Compare this with the expected output to verify that the rectification process is functioning correctly. For more thorough testing, apply a load to the output and monitor the voltage to ensure it remains stable under load conditions, indicating effective rectification and regulation.

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.
