content: Hi Folks,I'm in research/shopping mode for a new power supply to expand my setup to include a higher current supply (20-40A+ out) that'll allow me to test high current converters.My needs are:- LAN connected (For testing automation)- Single Output- Banana Plugs on front (in conjunction with rear terminals)- 400W+ Output (20A min. 40A would be nice)- Small form factor (I'm running out of space faster than I can make it)- Bonus: Sense (Front accessible preferred)- Budget: $1-2k New.I've been looking at Kikusui's PWR401L/MLhttps://www.kikusuiamerica.com/product/detail.php?IdFamily=0143But I'm wondering what other makes are out there that I could look at or if others have suggestions.Thanks!

content: AIM-TTI QPX750SP looks suitable. For high power you can look at server rack PSUs like TDK-LAMBDA GEN-60-25/LN.

content: It won't set the world on fire in terms of specs or features, but if you want compact and high current, I've got a BK Precision 1900B and there are a couple of older and similar models that are frequently pretty affordable on the used market (and in budget new).

These are small but quite long.I have the 60A 40V SPS5042X that will soon go to Defpom for review.Unfortunately for your needs these have zero front panel connectivity.https://siglentna.com/power-supplies/sps5000x/

The PSI-9000T looks to have some attractive features as well. The power switch on the back for the PSI is the main downside that I can see, but the form factor is what I think I'm looking for.Really appreciate highlighting some great options from everything that's out there.Cheers.
