content: Hi Guys,My first post, hi all! I work mainly on uC programming with a passion for audio electronicsIt looks like a new Keysight power supply is announced today with release in November 2022It would be great if it is a 4 quadrant supply like a Kepco thing.A waveform generator is present too. Great if it would be possible to superimpose a waveform on the DC.In the video it looks also it has some oversized connection terminals. Maybe some models >100V DC?Does anybody have more information?

content: I wonder if Keysight thought the Envox BB3 was such a capable unit that they should copy it, put it in a posh case for 10x the price with less support and everything useful as an "optional upgrade".May I politely suggest that if you are looking for something with these capabilities at a very affordable price check out the BB3. Max 80v (series) 10A (parallel) and yes it can superimpose the arbitrary signal on top of a DC voltage.It has fantastic development software (free!) where you can design your own GUI and scripts, all open source.I admit the case is not as slick as the Keysight but the tech support is the best I have known in nearly 50 years in the business.I now have 3 of these in my workshopshttps://www.envox.eu/eez-bb3/https://www.envox.eu/studio/studio-introduction/

For new power supplies, there are *much* better options - Siglent, Rigol etc for the consumer/hobbyist market. At work, I very much like various models from Chroma - full featured, durable and with very good manufacturer support.For personal use, I use a couple of Power Designs TP340As as well as a C500. Kikusui linear supplies are also *highly* recommended.Hal

content: Quote from: 2N3055 on September 18, 2022, 10:24:06 pmI agree. It is nice to see though that Keysight brings this old concept back to life. In the HP days they used to have a whole bunch of these kind of supplies that have a power limit. It makes a PSU much more versatile. I have a pair of HP6012As which are excellent for when a lot of current or high voltage is needed (and the power limit is kind of a conservative estimate). Still, I would like some more modern metering though.

content: Can you charge a battery with it?Don't see mention of it in the datasheet or app notes, no precautions etc. unlike the EDU36311A which requires a lame output diode.Regen, backspin, large capacitive load, battery potential etc.- unexpected voltage at the output terminals does happen.I expect a power supply to be robust and cope with any load. Not crowbar it and don't take the backfeed and auto-destruct.I can't get excited about a product, no right to repair- access to a service manual or at least a power-section schematic, that can get damaged with a common use, and asking Keysight Support over their shortcomings I've been through that and don't waste time taking blame for their own engineering omissions.Can these new power supplies withstand voltage at the output terminals (4-wire sense as well), when powered off, or the output disabled, or above the setpoint? Yes the OVP function is obviously not enabled when working with these type of loads.

Or the pass transistor array etc.While charging, pull the power cord as if a mains failure occured. Or with the power supply off, connect a battery to the output terminals. Many PSU's I've seen killed that way or worse as batteries can punch harder. Here we have a ton of firmware with devs not knowing about this issue.I noticed press releases pulled a couple weeks ago, not sure what that is aboutI did see: E36155A USD $3,845 60V 40A, E36150ADVU USD $532

content: The E36300 User Guide has a paragraph (see clipping below) about this (talking about OVP) where they recommend a diode to avoid backfeed and even putting the sense wire on the PSU side of the diode, which may make sense to keep sense and terminal within range but makes the sense input a lot less useful.OTOH, the TTi QSP series, which is a hybrid very much like the Keysight supply of this thread (including the very similar and much cheaper QPX750SP mentioned above) claims:"Output will withstand an applied forward voltage of up to 70V. Reverse protection by diode clamp for reverse currents up to 3A"So it seems that that particular series of supplies can survive a battery backfeed.I also looked at the Electro Automatik PSI 9000 DT Series (recommended as a high-power supply on this forum). The situation is not entirey clear. They have a section on battery charging. They clarify that they don't have reverse-polarity protection but they don't recommend an external diode for backfeed.

That's similar to warning people not to use float scopes every time someone suggests doing that.N.B. as someone that was very appreciative of HP support policies, and who worked happily for HP for 13 years and loves HP kit, the Keysight attitude pains me. I think it deserves to be mentioned when appropriate.

You have to keep in mind that this could be single incidents related to people's attitude and/or the question being asked. And even if Keysight doesn't give direct support, you can always get in touch with the dealer that sold you the equipment. IMHO there is a lot of parroting from some very vocal people and very little substance. No need to pollute other threads with stories that could even be classified as 'fake news'.

For the Aim TTI PSUs it seems you need to use PC software for the more advanced functions while the Keysight PSUs allow to do all the programming on the PSU itself. Personally I'm a great fan of test equipment that can be used to the fullest extend without needing PC software. Recently I needed some voltage sequencing and that is easy enough to configure on the Keysight E3631x series PSU.

content: The Keysight (Australia) Terms of Sale document from their ebay store basically says "When you buy from us you agree that you are not using the equipment for personal, domestic, or household use. If you are using our equipment for those uses, we cancel any software licenses and void the warranty". Support isn't mentioned, but the implication is obvious. The same section is present in documents from other countries including the U.S. and Canada.https://www.keysight.com/au/en/assets/ndx/9018-60025/exhibits/9018-60025.pdfSee section 7(j) on the third page.One reason that it seems to be getting mentioned alot is that it's new and bizarre.

Still, I don't think this language is uncommon ("we only sell to business customers", "only suitable for professional use", etc). But many companies seem to have a "don't ask, don't tell" policy in practice. Basically, as long you don't explicitly state that you are buying for personal use or ask for clarification like you did, they just ignore it.This is clearly about consumer protection laws (return policy, warranty, dispute resolution, but also additional safety or EMC regulations that may apply).

content: I think Keysight needs to formally explain and clarify their policy. Otherwise that steaming turd will continue to stink up the forum.Saying it's "legal" doesn't cut it. They make specific educational market goods to be used by students, sell to the school - yet won't sell to hobbyists/sole proprietors/students?The only explanation I can come up with is Keysight attempting to close backdoor sales to hostile countries, after the$6.6M finefor export violations selling test equipment (radar analysis software) to the commies.OK you now want total control of your sales channels, but the mob will always find ways around that. IDK if there's more paperwork and traceability.This new DC power supply family can't really be an instrument of war, nor a bench multimeter - so why else discriminate against the small fish?

content: I don't underestimate a user family and support yet, as a hobbyist, I wouldn't put all my eggs in one basket with regard to equipment manufacturers.I'm in a function gen, an insulation tester/dmm, and another dmm with Keysight and that seems about the right amount for me.

Quite possible that this made the legal department realize that they were potentially selling directly to consumers and they went "wait, what, are you !@#$% mad, you can't do that".
