Any have a 48V p/s they don't need?

[Tom Keddie]

Was looking on ebay but thought I'd try here first. I'm looking for
48VDC from 110V, 250W or more.

I might try the hackery tonight, 48V is a bit esoteric though.

Thanks,
Tom

48V is used in Telco equipment. It's being phased out mostly but you'll still find the external supplies for high end POE injectors (rather than the 24V used on the low end injectors).

I have a 48V 2A power supply so 96W. What do you need it for?

[Tom Keddie]

I have some ATCA (telco) cards that belong in chassis but I have more cards than chassis that I want to power up.  A 2 slot chassis is using 2.6A at 110V, empty chassis about 0.5A so I think I need about 120W per card.

I could bypass the onboard 48V->12V DC-DC but it is mounted on the PCA with multiple 10ga pins that aren't going to desolder peacefully (unless people think it would be safe to apply power behind an unpowered DC-DC without removing it - seems too risky to me).

Thanks, I think 2A is a bit close to the wind given the above.

Cheers,
Tom
