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 (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 (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 (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 .

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
