content: Hi, I'm new here and yes I did search the forum, but let me know if I missed anything.I am looking for a new general purpose lab power supply. Looking around quite a bit, I found the HAMEG HMP2030 which looks quite good, but has it's price (around $1700). For a little more (+$500) there's also the high-end HAMEG HMP4040. I already have a HAMEG product (analog oscilloscope, bought many years ago) and I was/am very happy with it.Link to description of the HMP series:http://www.hameg.com/h008_hmp2030.0.htmlQuestions:It looks like the HMP series came out in 2008, so it's almost 8 years old. Is this PSU outdated and something better available?Is this worth the money?Would you buy the 2030 or the 4040? The 2030 would be enough for all what I could think of right now. But I mean the 4040 is just slightly more expensive but has an additional channel and much more power. Only disadvantage is the size of the 4040.Are both quiet (silent) if not using much power?Are there any other products with similar quality available?I'm an electronics engineer, but not working in that area anymore for decades, so it will only be used for some hobby projects. Money is nota big problem, because I only want to buy such a thing once in my lifetime (unless I really need something special).

content: If your power requirements would by met by 100W, the HMC8043 is much newer design than the HMP and costs about 1/3rd less than the HMP2030.I have one and it's fantastic. I had been looking at the HMP series but the display looked like it would be very hard to read from a distance. The color LCD on the HMC has so much contrast it looks like an OLED.

content: Sounds like overkill. Should be pleanty of options around. New/Used keysight/rigol etc.https://www.eevblog.com/forum/testgear/hameg-psu/https://www.eevblog.com/forum/testgear/hameg-hmp2030-psu-new-arrival-at-least-in-my-lab/> deleted his post?You might put a WTB in buy/sell forum.

content: Thanks GlowingGhoul and nowlan. Not sure why I missed the two threads there when searching, but that was a good read too. Regarding the HMC8043, this is indeed another option now. Although I don't like the frontpanel layout (looks too complicated; the HMP4040 is much cleaner) and although it has no sense input on the front, I still like it, due it's much smaller size and weight. Although, if I look a little closer, the weight doesn't matter in the lab and the size isn't that different. I don't care much about the display brightness. So now I have one more choice:HMP4040, 285x125x365mm, 10kg, $2167, 384W, numeric input, nice frontHMP2030, 285x75x365mm, 8.5kg, $1616, 188W, nice frontHMC8043, 222x88x280mm, 2.6kg, $1189, 100W, new model(size WxHxD, price includes 8% VAT)Quality is probably superb for all and fan noise negligible, if not using much power.Overkill? Yes, maybe, but it doesn't really matter.I'll probably go with the HMC, because I don't think I'll ever need more than 100W and I prefer a model that is not already 8 years old when buying it new. It is also more transportable if I ever need that.
