HI.
I was considering to buy a Rui Deng DP 5015 / DP 50V15A https://fr.aliexpress.com/store/product/RD-DPS5020-Constant-Voltage-current-Step-down-communication-digital-Power-Supply-buck-Voltage-converter-LCD-voltmeter/923042_32821185351.html?spm=a2g0w.12010612.8148356.1.78933931XSezfe or DPS8005 programmable power supply but have no DC PSU supply for it. So I would need to buy one.
For my previous DPS3005 (30V, 5A) I use an old 20V laptop supply witch was free, but for the one I'm considering now, I don't know where to find a proper PSU supply.
What do you use ?
I've seen some https://www.ebay.fr/itm/500W-72V-6-9A-220V-INPUT-Single-Output-Switching-power-supply/222240260342?hash=item33be8d40f6:g:5WAAAOSwknJXzPsn or https://www.ebay.fr/itm/500W-60V-8-3A-220V-INPUT-Single-Output-Switching-power-supply/222241238393?hash=item33be9c2d79:g:b9IAAOSwknJXzlmE
But they're are getting quit expensive and don't fit exactly the needs (only 6.9A when the DPS5020 witch needs at least 20A !)
What do you use on your side ? Or what advice would you have ?
These little DPS programmable bench supply are very practical .
metrologist:
With the 5015, the most practical is probably a 48V switch supply. I just had one in 36V and use it fine. I plan to use also a 36V Li-ion pack for portable operation.

For DPS5020, you can use that 60V power supply, but that current is too small, you can search a more big current switch power supply, it should be ok
in fact, you can search a 60V/20A switch power supply, it should be ok ... but when you use , please lower than 60V to use , it will be safe

in fact, it depends on your need, only input voltage is on the range, it will be ok
