Hi guys.

I urgently need a power converter designed and built as inexpensively as possible. Future purchases guaranteed!!

**CASH WAITING!!**

I live in the UK, so if it could be designed (and built) here, it would be appreciated.

Please see here for details of the voltages required.

I can provide the 5v and 12v from a PC PSU, but need the 80v and 100v dual transformers. An all in one (5v, 12v, 80v & 100v) transformer would also be great.

I'm concerned that if I was to design this myself, it would fry my very expensive DMD board or set fire to everything in near proximity!!

Thanks in advance to every replier.

 

Hi Packrat.

We run at 240v in the UK.

It appears the amp required are fairly low, Max of 2amps??

Sorry, but I'm not too great with working with anything over 12v, so everything is worrying me a bit...

 

Thanks again, but I'm afraid your last post is complete gobbledegook to me

Unless it's simple enough for an 8 year old to understand, I'm knackered! LOL

...if you could simplify, I'd appreciate it. Thanks.

 

The UK supply is one phase of a 3ph transformer and a grounded neutral.
240v 1 phase.
No 120v.
BTW, all the voltages in the OP, are they at the DC level or AC?

Hi Max,

Pins shown on the rear of the DMD board:

Vsn
Vrw
key [blank pin]
GND
GND
Vcc
Vcm
Vsp

And how I presume they should be powered (according to the pdf)

Vsn___________-110VDC
Vrw___________+ 12VDC (- 98 VDC)
key [blank pin]
GND
GND
Vcc___________+5VDC
Vcm
Vsp___________+75VDC

 

Bear with me, I'll either find you a schematic to clarify the issue, or I'll draw one and post the drawing...

Thanks Packrat, I appreciate it.

DC voltages obtained by a linear supply transformer are calculated as AC required = DC x .707v.

You appear to be covered by those with more experience... Cheerio !!
