How to test the rectifier bridge is good or bad?

First of all, simply test the energization of the rectifier bridge with an electric pen, and you can test the energization function of the rectifier bridge. This is the method that general manufacturers will use before starting up.

First of all, simply test the power-on function of the rectifier bridge with an electric pen. This is the method that general manufacturers will use before starting up.

This method can only simply test the quality of the rectifier bridge, but it avoids the short circuit problem caused by insufficient power supply of the rectifier bridge in front of the computer, and avoids affecting data analysis.

The second method is to use a multimeter to test whether the rectifier bridge is good or bad.

Generally, there are two methods to test whether a rectifier bridge is good or bad with a multimeter, one is the voltage test method, and the other is the resistance test method. These two methods are simple circuits formed by adjusting the multimeter to different gears to test the voltage and resistance of the rectifier bridge

The second method is relatively more accurate.
