Ok, so this topic has gotten to be over my head. I really don't know what any of you are talking about when you mention creepage and double insulation, etc. Some explanation would be appreciated. But to my original post, I'm just looking for a decent SMPS that can supply +-65v, 1000w, 8-9A...

So far I'm hearing that the contenders are: (2) Hypex SMPS400, ColdAmp SPS80HV (although its a little too tall), Connexelectronics A1000SMPS, and Digiamp SMPS1000 (although I'm not sure if I can obtain it in the US). Any others I should consider? Of those listed, any red flags (in simple terms)?

Attached are screenshot with clearance distances measured on the current version. the version which you used for reference is early, version, not produced any more, but yet fully working. the capacitors used are the largest ones, 35mm footprint instead of 30mm which should be used on that particular version to meet the safety distance. The clearance distance between the transistor Drain plate and the mounting screw is also enough considering that there is a virtually airtight seal made by the insulator sheet, like Pafi mentioned in an earlier post. i believe that the manufacturers of the TO247 parts considered this aspect when they were developed.
I would not mind to test the power supply for safety by a third party organization which is not biased towards any competitor's product if looks that suspicious for any of you, and tell us the result.

The SMPS400 AND SMPS1200 are both designed for CLass II isolating. We use in the SMPS1200 Kunze isolation material >0.4mm isolating thickness.

The SMPS400 is having a safety certification (done by TUV), customer can drop us an email and we send you a copy. We're in the process to get a safety approval for the SMPS1200 and SMPS3K as well. So far we've designed two other OEM projects, the safety approval was rather easy to get.

Hi,
which model of amplifier you will need the SMPS? (A-B / D)
where it is used the amp? (home.. SUB, PA, etc.)

The Audiopower DPS-500 would meet your requirements also.

A quote from the specifications:

"+/- 68V 10A (16A repetitive peak current)"

here is the data sheet:

http://www.audiopower.it/datasheet/DPS500-52_EN1-3.pdf

I have not used one but certainly looks like a good product. Can be adjusted to 65V.

Hi,
Just for correction, I put the pdf correctly (new release).
you can use the DPS-500-S-64V in this case.
If you mean + /-68v with a 50Hz toroidal, then with these models is correct + /-64V. (700w under load burst, the drop voltage is about 2.7 V). ...just for percussion & symphony.


Regards

Hi,
Thanks for your time, I sent you an email regarding the translation of the article but this is not a translation error, it is simply deleted "NOT". thanks anyway.
now is correct.

Well, so I recreived simply a strange version, which has oversized caps.
The discussion about the sealed creepage on the MosFets is something I personally can follow by my personal horse sense. The opinion of certification institutes you will probably only find out, when you really present it there and I see you are confident about acceptance.
