FYI to all: Of the 1,600+ UltraCap LPS-1 units sold, we have had 10 field failures--virtually all due to overvoltage input spike frying a particular regulator chip. 7 of those 10 were from people charging their LPS-1 with an HDPlex power supply. We can not cover under warranty failures caused by third-party "energizing"/charging supplies. HAPPY NEW YEARS to everyone! And thanks for making 2017 a terrific year for UpTone Audio. --Alex C.

I think the old one was 160W and all outputs shared the same -0V, the new one is supposed to be 4 seperated rails but in my 200W I can only see 3 outputs from the transformer and 3 rectifiers so I think 2 outputs share the same windings on the transformer. I suppose the electronics in your LPS-1 is rated at a 12vdc maximum but at what voltage does it fry the circuits? I have not yet connected my HD Plex 200W that will power my ISP fiberconverter, router, switch and NUC with Roon ROCK but this problem with over voltage have me a bit concerned about using it. Most of the stuff I will connect have their own DC/DC converter so perhaps they are not so sensitive to a short overvoltage input? agladstone 1 Main system TAD D1000mk2, TAD M2500mk2, TAD CE-1, Ansuz Mainz 8 C2, Ansuz Darkz D-TC, Qobuz Studio -> Roon ROCK on NUC -> Uptone etherREGEN -> dCS Network Bridge -> AES/EBU -> DAC HD Plex 200W PSU (4 rail for ISP fiber, router, etherREGEN and NUC) Second system Qobuz Studio -> Devialet Silver Phantom, Devialet Tree Link to comment

Sometimes the fixed outputs, sometimes the variable, and often failure of the HDPlex in the process. And the LPS-1 is not always the only item damaged. Since virtually all the support we provide is via e-mail (though I enjoy phone calls as a break and such are often more productive than e-mail), I have documentation of all this--plus the returned boards with burnt parts. It is not my intention to be negative about the value-oriented HDPlex units--and I understand that Larry Liu provides excellent support to his customers. I just felt the need to point out that we can not warrant the LPS-1 against damage by excessive voltage from 3rd-party supplies--and for whatever reason an HDPlex was involved in 7 of the 10 failures we have seen.

If you have further questions about this matter, please write to me. So as an FYI, I currently have 2 HDPlex 100W’s and I actually just ordered a new HDPlex 200W that will arrive tomorrow. Larry told me that the older HDPlex 100w’s do not have OVP/OCC and that the new HDPlex 200W now does (plus an EMI /RF filter). I cuirently have my LPS-1 being powered by an older HDPlex 100W at 12V, after reading this, I think I will immediately revert back to using the Meanwell SMPS with a JSGT!! I have the other HDPlex 100W powering my Brooklyn DAC, so after reading this I’m anxious to get the new improved HDPlex 200W tomorrow since I don’t want to fry anything with these older HDPlex 100W’s! I’m planning on using the two old HDPlex 100w’s on my Modem, Router, and Netgear GS105 Switch. Do you think the smartest move would be to just replace the 2 HDPlex 100W’s completely and. It even risk using them on my network equipment? I never realized that they did not have OVP/OCC! Thankfully Larry informed me of this last week when I ordered the new HDPlex 200W. Oddly his advice to me was to sell them and NOT use them! Seems like they’re actually unsafe per this information about the fried boards in the LPS-1! I guess I better start putting a JS-2 fund together fast for my DAC! Link to comment

Seems like they’re actually unsafe per this information about the fried boards in the LPS-1! A small amount of over voltage on a 12V nominal voltage rail used for powering most 12V rated devices will not matter. However, a smidgin over 12V is the highest permissible voltage input for the JS-1. It also seems likely that some of the failures may have been due to users fiddling with cables etc. with the power switched on, causing a momentary voltage spike or even failure of the HDPlex. The 19V Adjustable voltage rail being set to +5V (as some members did) with a reasonably heavy load such as a USB card etc. , would also have caused this module to get quite hot, and in some instances did cause the voltage regulator to go S/C causing >19V to be applied to the powered device, which was also irreparably damaged ! Repaired/returned modules came back with overvoltage protection fitted. How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file. PROFILE UPDATED 13-11-2020 Link to comment

Your would never regret that. About 50 Brooklyn DAC owners bought JS-2s in 2017 (I ought to write to Mytek to ask to be listed with the other LPS units on the Brooklyn page). There are qualities to the design and execution of our choke-filtered, dual-output unit that go beyond just its 5-7-amp rating and make it an exceptional performer with a real audio component such as a DAC. And the JS-2 is easily the most reliable, trouble-free product I have ever produced. We have more than 600 of them out there with only two field failures ever. In December we managed to build ahead a bit, so as of today there are 8 units ready to go at any time (though they won't last on the shelf).

I have tested my 200W HD Plex and to me it gets rather hot just runing around 0,5-1,5A on each of the four outputs and the variable set to 19V. Larry wrote that 70 degrees is ok as operating temperatur but to me that is not ok in the long term as my will power network equipment 24/7. The 19V and the variable 19.5-5V output share the same winding and rectifier so not four seperate outputs. So the 200W model do have overvoltage protection from the begining?

While it certainly is nicely made, I do not see anything about it which would give it an actual performance advantage over a good Switchcraft part. Sure it has gold plate (almost certainly thin gold flash over a nickel base) but at DC the current is going to be traveling through the base metal anyway. And the base metal is brass or bronze and not copper. I have never been able to find any DC barrel plugs made with copper, too bad, as the part seems like it could easily be made from copper... gstew 1 SO/ROON/HQPe: DSD 512-Sonore opticalModuleDeluxe-Signature Rendu optical with Well Tempered Clock--DIY DSC-2 DAC with SC Pure Clock--DIY Purifi Amplifier-Focus Audio FS888 speakers-JL E 112 sub-Nordost Tyr USB, DIY EventHorizon AC cables, Iconoclast XLR & speaker cables, Synergistic Purple Fuses, Spacetime system clarifiers.
