content: Listening to the5th videoof the highly informative and enjoyable John Kenny series, he mentions that they have new power supplies planned (obviously), and I was wondering what that could be given the current range of products (especially if the UI and form factor are related to the new E3631xA).Here is the current range as I understand it:Single output:* U800xA ($440-550): 90-150W. Backlit LCD display. Non-programmable.* E3610xA ($900): 30-40W. Green OLED display. Programmable. LXI/USB. New.* E364xA ($900-1060): 30-80W. Green LED. Programmable. GPIB/RS232. DMM form factor.* E363xA ($1250-1520): 120-200W. Green LED. Programmable. GPIB/RS232. Big.Dual/triple output:* E36320A/E36330A ($680): 40/50W. Red LED. Non-programmable.* U803xA ($1440): 375W(!). Backlit LED. Non-programmable. Big.* E3631xA ($1100-1700): 80/160W. Color LCD. Programmable. LXI/USB, opt GPIB. New.* E363xA/E364xA ($1140-1440): 80/100W. Green LED. Programmable. GPIB/RS232. BigThere might be space to replace the lowest-cost non-programmable ones (but is that a thing anymore?).The U803xA with high power is a bit by itself.I assume the E364xA/E364xA are essentially replaced by the new E3631xA?I am not sure what's left. Maybe the DMM form factor E364xA? Not sure what that niche is.All in all, I am not sure I see where they are taking their wave of new DC supplies next, especially if it's based on the new E3631xA... Given what they've done on the DMMs with the slightly-upspecced 34465A coming just a couple of years after the 34461A, anything is possible (just to add an actual off button?).Maybe hybrid switching/linear supplies like the high-power and flexible V/A TTi supplies?

content: Quote from: LaurentR on October 25, 2017, 04:49:30 amIsn't the U80xxA the replacement series for the lowest cost, non-programmable PSUs? They also have a toroidal transformer like the other new Keysight PSUs and they are very heavy with 8.3 kg, heavier than the big and old design of the E3631A.May be in a few years all Keysight PSUs will have the same or similar color LCD screen with lots of valuable information on them. And hopefully they will stay with the concept of separate knobs for current and voltage.

content: I saw there is a competition over the next few weeks to win one of these new psu.I think the black casing reminds me of Lecroy.The E36311A 80W seemed a little wussy for $1500 psu.Output Rating- 80 WOutput 1: 0 to 6 V, 0 to 5 AOutput 2: 0 to +25 V, 0 to 1 AOutput 3: 0 to -25 V, 0 to 1 A

content: Thanks @nwolanHere's a thread on the contest:https://www.eevblog.com/forum/contests/power-supply-contest!-free-e36312a/The $/watt isn't groundbreaking, but there's definitely more to choosing a power supply than just the wattage.Also, it's $1100 for the E36311a, not $1500 (USD on keysight.com as of 26-Oct).

content: The E36313A looks like a grown-up version of the ever popular DP832(at 3x the price)I am seriously considering it but even the E36313A is a bit low on power (for example, I understand the choice of ranges but it turns out to be able to output only 4A in parallel vs 6A for the DP832 @8V, which turns out to be a common use for me, emulating a 2S Lithium battery).I was wondering if there is something coming that might be a notch above the E36313A power-wise (the rest is great) - thinking again of the mild 34461A>34465A upseccing that happened in the DMMs.

content: That's a valid question, but I can't really comment other than stand by John's comments (because I don't really know).
