Hypex DLCP with linear PSU?

[Vermouth]

Hi, I think the PSU on my Hypex DLCP has failed, (no lights on either board).

I have a couple of HDPlex linear PSU's a 100w version and 200w version. The latter has a adjustable output so can put out 18v.

Would these be at all suitable for powering the DLCP?

Thanks in advance?

Are they both 18v?

Incidently, I still have the all in one ucd amp from hypex that has a built in osu with +/-18V out if you want to try that. Also I'd be interested in a dlco if you have a spare

Its currently in a case with a pair of UCD and a single power supply SMPS1200A180 for the amps, which seem to be fine.

Do you have any more info on the all in one UCD amp?

Here is a pic of the 200w linear power supply, it has lots of outputs, a fixed 19v which was driving a intel NUC, but the adjustable can be dialled in to 18v.

But I may look to sell, I do have a cheap UCD 6 channel 36w for testing to use as an active XO development board.

I suspect we have the same UCD - mine's a UCD32MP v3, I guess yours may be the UCD36MP. Incidentally I've never actually hooked up the power amp side of it, only ever used it for the balanced 18V outputs, that's a useful feature from mains in. And though it should make no difference, there was a level of peace of mind using a hypex psu with a hypex board.

Let me know if you'd like the UCD32 or want to just get rid of the DLCP... fair warning, I wouldn't be looking to pay much for a board that may be broken, had one broken DLCP already and spent far to long trying to wrestle it back to action

The two amps in the case currently are the UcD180HrX, with the separate power supply, but I have the UCD36MP as well that isn't connected up.

Do you know which output I would connect it to for the DLCP use?

I'm Bristol, where in the uk are you?

XLRs for power? Sound a like a trap booby trap for anyone who isn't fully aware .. careful there!

 

[nannoo]

There's a spec sheet online somewhere, I'm in oxfordshire, just a bit too much of a drive from. Bristol I'd expect!

There's an application sheet online somewhere for the ucd 3X series amps. The jumper is relatively simple, but you need to jump two pins together to turn on/take out of stanby, then the 18V is a available. As always, worth measuring first!

And quite agree, XLR isn't ideal for power outputs, but if it was for DIY sometimes you just use what's to hand! I'm a big fan of molex connectors personally.

Does anyone know if I can use an output on the SMPS1200A180?

To power the DLCP? I don't see how, the voltage is far too high. Why not just use the ucd36?

 

[Vermouth]

I can use the smaller one, but it would mean removing the 180w UcD's which power up fine, and it's all nice (ish) and neat in the case.

 

[nannoo]

I don't see any reason to remove the 180W ucd's, just remove the DLCP power unit and replace with the UCD36

 

[nannoo]

You'll need to check the pinout mind, it may be that the dlcp input header has the same pinout as the ucd header, but that's not really hypex style. They tend to go for odd engineering decisions where they can!

 

[nannoo]

Seeing as you also have the i/o board, I'd def be interested in buying the DLCP & gubbins if you keep the 180W UCD's / psu

 

[Vermouth]

I didn't clock there is a little fast blow 2a fuse in the DLCP PSU, I've ordered a replacement to see if it works.

 

[Vermouth]

The fuse didn't work.

@nannoo do you know if the UCD36 board can power the amps & the DLCP. It would be nice to simply the internals for quick speaker testing.
