Astron Power Supplies Questions
Hi guys
I'm looking to pick up one of these for a couple receivers. Now I seem to have run into a concern. I did some research and found several models that don't offer crowbar overvolt protection. The RS-3a, RS-4a, 5a, and 4L and 5L. But, I see they have a primary fuse on back. Now take the RS-10a. It has crowbar protection, but no fuse for a primary overvolt. So I figured if they have crowbar, they don't need a fuse. But now I have found Astron models with crowbar but some use a fuse while others don't. So what's the story here? Which one is best? One that uses both a fuse and has built in crowbar protection or it doesn't matter as long as they have crowbar? Why do some use both then? Why do some not use a fuse at all? That doesn't seem to make sense. Thanks for replies Lucky |
