In the plating industry application, normally, there are two types of rectifier, which is:
1, Silicon controlled rectifier.
2, High frequency power supply.
While, what is the different between for the 2, sometimes it will cause us confused to choose them.
Here we use a table sheet to find out what exactly difference for them.
For easy to distinguish, we choose same power: 1000A 12V type rectifier. From this, I think you will know which one is what you want.

Hi. I need a help to understand , What kind of rectifier is the better for ácid high chloride zinc process for cast iron ?
Thanks!
