https://www.amazon.com/Programmable-MPS-3033X-Adjustable-regulated-Resolution/dp/B08W28FF9D...Oh, did I mention its $299 with coupon code!? LOL
This looks to be a good option for somebody looking for a cheap lab PSU. Unlike Siglent's counterpart, it has a keypad, unlike Rigol's counterpart, it has isolated outputs. The readback accuracy isn't stellar though.
Unfortunately the coupon code seems to have disappeared -- it was there last night but it's not showing up for me now.

So far, near identical software operation as a BK Precision.
Cons:From what I can tell, the large caps are YMIN brand? Never heard of them, but they are rated for 105C.Loud relays.Initial output enable ramp after power on looks pretty janky. Subsequent output enables looks cleaner, but still a small non-monotonic section. (supply set to 32V 3.2A connected to scope only). Can anyone comment on what this should look like? My BK Precision 9031B is cleaner, but also has a step ~2V so maybe this is a characteristic that is expected to some degree?Banana posts not standard spacing. Used 0.85" instead of 0.75" (really!? ...)I know it isnt much of a checkout yet. Ill get a programmable load to really stress it out. Please let me know what testing and output I should do and capture! I know that Dave like the constant resistance 1Ω stress test.
