Choosing a power connector + switch for the Sigma 11

post #1 of 3

Hi Guys,

So I've got all of the parts (just waiting for the MOSFET's), and I've started planing the case (it'll be the 1455N2201, since the transformer is the Antek Inc which is 3.0” Diameter x 1.5” High). I've ordered a power connector + switch a few weeks ago, and was planing where I'll put them when I remembered I had something similar I bought a few month back.

I took it out to make some measurements, and it fits the case with the transformer + PCB inside. Only problem is, due to its size it'll leave less space inside (things get pretty dense inside once I use this one). On the other side, it does have an internal LC circuit, which I'm not sure will be needed as the Sigma is probably filtering it all anyway. Here's a couple of pics of the two options:





And the LC:


Which one would you suggest? I just have to decide which is more important, the filtering offered by the larger one, or the extra space inside with the two small ones?

In my experience, the AC line filter is entirely optional. If you have the space for it, sure, why not. But if not, no big loss. I've not been able to measure any tangible difference with or without it. Maybe my AC power is cleaner than usual? Who know...

That's just it, it fits, but it leaves very little space inside, and I don't really like all of these things getting stuffed that close to each other. Iif you say you couldn't measure the difference when using one of these, I guess it isn't needed for the Sigma11.
