Can the KPA500 be installed on it's side? There are feet there. I want to
install it in an RV and there is more room for wiring and fan air movement that way. A search did not turn up any answers. 73, Mark W7MLG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
The feet are there for transport. I'm betting, because the way the case
is designed, that leaving it sitting on its side is probably not a good idea. But I don't have a concrete reason, other than the weight of the transformer and the design of the case. 73, Scott N9AA On 7/8/18 1:56 PM, Mark Goldberg wrote: > Can the KPA500 be installed on it's side?

In reply to this post by Mark Goldberg
Just last week I sent the same question to Elecraft Support. The answer I got was yes, it can be, with two caveats. First, be sure to leave the 4 inches of free air clearance next to the top (top as in standard orientation), and don't set it so that the LEDs are on the floor. The orientation isn't odd, really. If it is resting on its right side the power switch will be on the rear, but very near the top edge. That's how mine will be, when it arrives this week --- I hope..

Oops. My error. I read KPA1500, not 500. Wishful thinking on my part.

To clarify - by "side" i mean the side that you would call the left or
right side of the case - that is what i'm considering to have down. Not the face or back.

I know that there are feet are on the right side of the case, but if I were to place the KPA500 on its side, i think I would create a stand so that it can sit on the left side. Why?
The big weight (power toroid) is on the left side, while the heat generators (the PA transistors) are on the right. The center of gravity would be lower, cables would be down low (especially the power cable), and the fans up high. The only heat generators on the left side are the power regulators (for +5 and +12V). They don’t generate nearly as much heat as the PA. The down side? The carry handle is on the left. That’s why a short cradle would be needed to lift the case above the handle extension. Just opinion, not an official recommendation. Mine sits nicely on its bottom feet with the KAT500 on top. That allows me to cable the two very nicely using custom cables. 73, Jack, W6FB > On Jul 8, 2018, at 8:25 PM, Jeff Blaine <[hidden email]> wrote: > > To clarify - by "side" i mean the side that you would call the left or right side of the case - that is what i'm considering to have down.

My other option is to put it a few inches above a Xantrex Prosine inverter
/ charger. On the road it will be powered by that inverter anyway, so maybe proximity is not a huge issue. I need to filter it anyway. They do have quite a bit of filtering in there already, but I could hear the birdies from the charger when it was running. It's a Sprinter based RV, not very big, and under the rear seat is where I have room and it is close to the antenna feed. 73, Mark W7MLG On Sun, Jul 8, 2018 at 8:49 PM, Jack Brindle via Elecraft < [hidden email]> wrote: > I know that there are feet are on the right side of the case, but if I > were to place the KPA500 on its side, i think I would create a stand so > that it can sit on the left side.

Actually the feet are on the left side, not the right. They are on the same end that the transformer is on and would be in the perfect position to sit standing upright.

And you are right! When developing the KPA500, we went back and forth as to which was the best side, so my memory can be a bit fuzzy there. Mine had no handle or side feet for quite a while.
There is still significant heat production on the left side since the side panel is used as a heat sink for three (I believe) TO-220 regulators. I would still get that up off carpet so that at least some air can flow through to dissipate the heat. 73!
