Consider that, hv (lme) is the output of this Aux SMPS, this output is in any case under controllers (onboard or external) and works only with constant loads.
sorry, I was busy, I did not read well the point (2).
in this case, there is no variation. (variable load on aux,not produce variation on power DC).

this is the only way its going to work. actually no i've had my hands/head a bit full, but anything else would be a big waste of money, particularly for us outside EU. i'll drop him a note now, though hes watching the thread its probably best by PM.

Hi Guys,
Think all know, just put on thread a standard version of DPS-600 suitable for this good Wire Amp.

Is better I finish datasheet instead put some features.
Just Important ..this model not work at 110Vac.
Some note on pic, as dimension, screw etc.

regards

Only you can answer those two questions

How many amps are you building and how much power output do you want?

Regards,
Owen

well that depends, since AP2 has said there will not be a 110v version, so if you dont have access to 220-240v mains or a stepdown transformer, it seems these people are out of luck in this case.

see above, this is the more pressing question, do you have 220-240v available?

I think initially this might be a good idea mate, just get these ones that are already suitable for 220-240v out there instead of getting bogged down in changes since we can manage the dps600 as is with some simple additional circuit to raise bias after initial lower setting. so do I remember correctly that you have enough in stock to cover the order as it stands (there will probably be a few less than 26 given the 110v only.

Well that certainly limits my options if the DSP600 doesn't support 110v

it would seem so i'm afraid. if there is enough demand they will probably make a 110v, but available stock does not. to be fair that was stated from the start and part of the reason opc took some time getting the testing done as he could only do it at work. but probably there will be increased demand after more get out there and you may even get a better supply with updates. so maybe just go with a linear supply using parts you may have on hand (I can probably even send you some caps mate) and watch this space I guess.

to do the 110v version there will be a whole new set of EMC testing that is needed, part of the reason Owen backed out of supplying them I presume. the dps500 on the other hand may be available in 110v, but dont quote me on that

Hi,
The standard version is in stock. For this model, the GB can help you get a small discount to the already low price (see dps-600/DA).
One note is that this version (will update and present only on site but not online shop), the reason is that this model is used in other areas (no audio), due to the weight and size, and the very low EMI emission / RFI.
This ensures a continuous production of the standard version.
As discussed earlier with Owen, it would be possible to 110V model.
This, however, has two limitations. only 105-125Vac or 230Vac and output voltage up to 50V (+65 lme). other than that, must be rebuilt compatibility (EMC) (SMPS have this certification), I do not think it can be addressed at this time, but if some company is interested, I think you can change everything.
I think the standard version allows to create a monoblock with new design, very compact for powers up to 400Wrms (4R) in class AB with new performances on audio, this is not little.

Regards
