FafeicyRectifier Filtration Module, 1200W 100V 12A Double Power Rectifier Filter Amplifier, Rectification Filtration Board with Four Rectifier Bridges, Module

When I tested my module, it didn’t behave at all like it should. After about an hour of trying to figure out traces on the board and meter probing, came to the conclusion that there was a bad connection somewhere on the neutral circuit, most likely on the side of the board that you can’t see. Adding a jumper fixed the board but if I didn’t have a pretty good idea of how to build one of these myself, it would have ended in the trash.

Oh boy, where to begin...This board seems perfectly fine and the build quality looks decent. The description says 100V but what they mean is two 50V AC inputs. You cannot run 100V through this board. Doing so will let out the magic smoke and give you an awesome fireworks show. Don't ask me how I know that. I gave this board 4 stars because it seems decent, it's clearly labeled with 50V inputs (on the bottom of the board), and you can read the component's specifications if you're ever in doubt. I did deduct a star because the capacitors are rated at 25V with series pairs, which means if you run full 50V in you've got zero headroom and you're maxing out the caps' tolerance.
