[R-390] OT:DC Power Supply for R-392

[Dave Maples]

Osamu: I don't think it would be any issue at all.  As I recall, the R-392
that I had worked just fine at 24 VDC.  That's been several years ago,
though.

If you are really concerned, you could always use two 14 VDC power supplies
in series.  I suspect the outputs are floating relative to ground, so I
think you'd be OK there; however, I really don't think you will need to go
to the trouble.

Hope this helps.

Hello All,

Sorry for the off topic.

I recently bought a fair R-392 (it will be on the ship on somewher in
Pacific Ocean yet).
But I don't have any 28VDC power supply.
I know it draws around 3 amps at 25 to 30VDC but it's really hard to find a
good
used 28VDC PS in Japan.

However, there are considerable number of 24VDC PS's with over 4 or 5 max
amps available
on used market.

So, I'd like you guys to give your advice on whether it can be run at 24VDC.

Thanks in advance,

Osamu Hazawa
