Just because a few have asked, I tried the following.

Question: Can you connect four in series?
I connected Four PSU's in series and achieved 48-49v DC..

Question: Do they work on 220-240v AC?
Connected a couple of these PSU's to 220v, and they operate fine.

Looking at your power supply set up. Very nice. How noisy are the cooling fans on this small sized unit?

[DSW]

I still have these available.

There might be some interest in these supplies on the amateur radio forums like QRZ and Eham. Only thing is when it comes to powering amateur gear they need 13.8 VDC along with the high current levels. Most rigs will operate to a point on 12v but the transmitter won't develop full output (and sometimes won't work at all) below 13.8v. Do you know if there is any output adjustment on these supplies?

You're offering a very good price on these things. I've got one sitting on the shelf I need to play with.

I had thought about the amature radio guys, but really didn't know what their requirements were. These are good quality power supplies, but may not supply their required voltage. I have not found a way to increase the voltage output.
Thanks,
