Yup, you can run the power supply vertically just fine.

KPA-1500 PSU mounting position
|
|
Before mine arrived a few weeks ago I put exactly that question to Elecraft Support. The reply was that there would be no problem mounting the PS vertically, so long as the air clearances are observed for the air flow -- I believe it's three inches at the top and at the rear, but the manual is pretty clear on that. I've mounted mine that way. When sitting on its side the On-Off switch is conveniently near the top-rear edge. Works FB.

Well maybe this requires a reply from Elecraft. They seem to be furnishing
conflicting information on this. I asked that question and here is the reply I received: Elecraft: Placement of the power supply can be anywhere within the 5.5 ft distance of the power supply cable and control cables, both of which are 5.5 ft. Air passing through the power supply is from left to right in a horizontal manner. This means that it will not work properly standing on its side. Seems logical that setting it on the side would restrict the air flow severely. I'd have liked to place mine vertically on its side but did not based on this. Mine sits under the desk on a riser so I did not lose foot space. I did not require easy access to the switch as I totally kill the equipment circuits in the shack at shutdown. 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 8/20/2018 9:33 AM, Dauer, Edward wrote: > Before mine arrived a few weeks ago I put exactly that question to Elecraft Support.

May I forward your note to Support, along with mine?

Interesting. I just told my friend W2irt that it was OK for vertical mounting of the power supply from the several posts on here a few months ago and I thought onewas from Elecraft. Its hard to imagine vertical placement of the power supply being a problem. It never even approaches getting warm unlike the rf deck.

Hopefully Eric or Wayne will chime in and answer this question once and for all. Since warm air has a tendency to rise, I could see where placement could be an issue.
An answer "straight from the horse's mouth" would hopefully put this issue to bed.

Peter,
If you mount the KPA1500 power supply vertically, put it on the front panel and there will be no interference with the air flow. Note that the LEDs stick out a bit from the front panel, so put the large part of the front panel on something that will be as thick or thicker than the amount the LEDs project - like a piece of wood or plastic. 73, Don W3FPR On 8/20/2018 12:09 AM, Peter Dougherty wrote: > Hi All, > My KPA-1500 arrived over the weekend and I've not gotten a chance yet to set it > up.
