content: Hello,I am looking for a 60V 50A (more or less) power supply, the power have to be at least 1kw. Possible candidate are HP 6032A, Amrel 60-20 and so on.Europe would be better but also USA is an option if the price is good.Thanks.

content: Hi,I have a PSW 30-72 I'm not using but it's only 720W. I thought I'd still comment though as you didn't mention the GW instek series. They're pretty cost effective and a few break the kw barrier.

content: 30V in too low, I need at least 40V, better 50/60. Thanks anyway.

content: Yeah you can place PSUs in series if they have isolated outputs that can support the voltage differences from ground. For example this cheap PSUhttps://www.amazon.co.uk/dp/B0836CV4V4/ref=cm_sw_r_cp_awdb_t1_KmcJEbM529D1K(Warning I didn't check the isolation)Its probably got very poor regulation but you seem only to want power? You can also series it with a low voltage but high current PSU like mine to get full current range regulation and partial voltage regulation. If you look, high current/power PSUs like the PSW series are designed to run in parallel/series and can link multiple units together (so they have the required isolation) but I have no idea where you could get another at a cheap price.Could you give more details on your application so we can better advise?

content: Got a Lambda/EMI TCR 40S45 inbound. Might be something. Also have a Lambda 30-50 (30V, 50A) and a Xantrax XFR35-35 that could be stacked

content: I just noticed this one on ebay uk which looks like it fits your requirements - the seller doesn't have any history and I know nothing about them but ebay are generally protective of buyers.https://www.ebay.co.uk/itm/BK-Precision-Digital-Bench-Power-Supply-1-2kW-1-Output-80V-60A/333570221374

content: I thought I'd just add to my previous post that I bought a (much cheaper) EA-PS power supply off the same seller and it arrived today. It is in good condition with only very minor marks and seems to work ok though I've only checked the voltage not put it under load.So despite the lack of history and the fact that the picture is only a stock photo it is a legitimate sale.The item has been re-listed:https://www.ebay.co.uk/itm/333576227570
