Seeking a 600W, 90-265VAC, off the shelf PSU of Vout = 51V?

[treez]

Hello,
We are seeking an offline PSU 90-265VAC , that can deliver 600W when vin = 90VAC.
The PSU should have a Vout of preferably 51V, but we will accept a 48V PSU with a vout adjustor pot, that can go up to 51V.
The size profile must be within length=300mm, width = 127mm, depth = 64mm.
All we can find so far is the Meanwell HRPG-600-48, however, this cannot deliver 600W when its Vin = 90VAC.
We have also found the Stontronics PDF-800-52, a 52V, 800W PSU (datasheet attached)
The Meanwell is just not capable of giving the 600W at 90VAC.
Meanwell HRPG-600-48 datasheet:
**broken link removed**

The Stontronics PSU has a fixed output of 52V, and we would prefer 51V.
Are there any other off-the-shelf PSU’s in the world which meet our needs?, Digikey doesn’t even list the Stontronics one. Do you know if there is an off-the-shelf PSU website that we can search?

If you need reasonably large quantities, go direct to a PSU manufacturer. In projects I have worked on in the past, it was cheaper to go to Astec with a custom spec than build in-house.

Alternatively, you could maybe step up your incoming AC with an autotransformer to bring it within the 90V input range of the other PSUs.

thanks, ive just emailed Astec. Unfortunately we cant step up the incoming VAC. Its strange that it seems to go blank after 600W, then you get more PSU's above 1KW.....between 600w and 1kw there is very little.
