edwardsean Posted June 26, 2020 Share Posted June 26, 2020 Hi. This is a basic question but do you need to turn off the unit before switching the voltage. I'm comparing two devices, with different voltage requirements. I'm been turning off the LPS1.2 while I turn the dial for fear of damaging the unit. However, i need to go back and forth as quickly as possible, and turning it off means waiting for the caps to charge. Link to comment
ray-dude Posted June 26, 2020 Share Posted June 26, 2020 I'll let Alex answer the direct question, but as someone that has generated the magic "Oh Shit!" white smoke one too many times, I've developed the discipline of checking the voltage of variable supplies with a multi-meter before plugging them into a new device. There is definite risk to moving quickly when switching supply voltages and devices quickly!

Hi Edward: Technically you do not have to power off the UltraCap unit before changing output voltage setting--though we prefer you do. But not doing so won't accomplish what you want anyway: Changing the setting of the blue output voltage switch puts the LPS-1.2 into a full reset and you'll have to wait. There are lots of states of voltage status that get checked and certain things must discharge--all in the name of self preservation by the UltraCap. It's prime directive is to survive!

Popular Post edwardsean Posted June 26, 2020 Popular Post Share Posted June 26, 2020 Thank you Alex, That makes sense and, of course, I'm relieved that such a feature is in place. However, that is also worrisome. The prime directive doesn't seem to make any allowances, ala Asimov, to not harm the human owner! At this point in my home, the machines far outnumber the humans. atxkyle and Superdad 2 Link to comment

JD123 Posted July 4, 2020 Share Posted July 4, 2020 Sorry if this has been asked before but have bought an LPS 1.2 to power a qutest and wondered if this was the correct adapter https://thepihut.com/products/microusb-to-5-5-2-1mm-dc-barrel-jack-adapter?variant=27740116753¤cy=GBP&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gclid=EAIaIQobChMIwtT1i7Wz6gIVCbrtCh0iFwjSEAQYAyABEgLdsfD_BwE Any help much appreciated Link to comment

Uptone use 2.1 mm, so that’s correct to. You may consider this. 😀 Link to comment

I know because that is the exact one we stock—to toss in free upon request—for UltraCap buyers with Qutest. pl_svn 1 UpTone Audio LLC Link to comment
Steffenegede Posted July 19, 2020 Share Posted July 19, 2020 Hi, I'm getting a kingrex uc384 converter that's supposed to draw 7.5v 200mA. I'm already using a lps 1.2 to power a microrendu so I thought maybe, if I'm lucky, the lps 1.2 would be able to power both? I guess there's only one way to find out, but would it be safe to try? I've fried a psu while powering two devices a while back.. so thought I'd ask before trying 😉 Link to comment
roman410 Posted July 19, 2020 Share Posted July 19, 2020 The power consumptions your microrendu and kingrex uc 384 converter it is way below the current capability of lps-1.2. You should be ok to powering both device's. I am using my single lps-1.2 to powering microrendu, singxer F-1 usb to spdif converter, wyred for sound remedy digital recklocker and 5 ldovr lt3045 boards with good success.

Haimsh Posted July 25, 2020 Share Posted July 25, 2020 Ok. I understand. I read in IFI PRO IDSD manual: “We strongly recommend the use of the included iPower Plus 15v. It offers the latest in power supply technology and is better and cleaner than any battery or aftermarket linear power supply”. What do you think? Will I hear significant improvement if I purchase and connect Js-2? Link to comment

bernardl Posted August 12, 2020 Share Posted August 12, 2020 My 1.2 is very hot when running. I have measured 58 C today with a Seek Thermal i have designed a heat sink that should improve things a bit but I would first like to understand whether the current level of temperature is normal or not. cheers, bernard Room: Gik Acoustics room conditioning | Power: Shunyata Omega XC + Shunyata Everest + Shunyata Sigma NR v2 power cables | Source: Mac mini with LPS running Roon core (Raat) | Ethernet: Sonore OpticalModule + Melco S10 + Shunyata Omega Ethernet | Dac/Pre/Amplification: Devialet D1000 Pro Core Infinity | Speakers: Chord Company Sarum T speaker cables + Wilson Benesch Act One Evolution P1 Link to comment

If the output load on the UltraCap LPS-1.2 is near the unit's 1.1A limit on a continuous basis, then yes, the temp you measure is normal. UpTone Audio LLC Link to comment

Popular Post Vincent C Posted October 1, 2020 Popular Post Share Posted October 1, 2020 I just want to say (but all of you already know this) that Alex runs a fabulous company... One week later, and I have in my system a new UltraCap 1.2 that works perfectly. And I live in New England, and Alex is in a very fire-y California. Fabulous service after the sale, and a fabulous product that works very well.. I'm a fan. Vince Superdad and soares 1 1 Link to comment
rjanderjr Posted February 13, 2021 Share Posted February 13, 2021 I am using the LPS-1.2 to power this fiber optical ethernet switch: https://mikrotik.com/product/crs305_1g_4s_in. The Power specs on the switch are: DC jack input Voltage 12-57 V Max power consumption 18 W Max power consumption without attachments 10 W Will this work? It is working fine for me and I wonder if I might be overloading it? rjanderjr 1 Link to comment

So if you are running "without attachments" (whatever they are) you should be fine. John S. Link to comment

It is working fine for me and I wonder if I might be overloading it? Depending on the SFP+ transceivers power usage, you might overload it. Optical SFP+ range between 1 and 2 watts usually. Startup usually sucks more power than just using. So if you have just one SFP+ optic transceiver you may overload the LPS-1.2. If you choose to use a copper wire (normal) ethernet SFP+ adapter then you will definitely overload the LPS-1.2 as they take up to 4W. So safer and better to look at the JS-2 which can supply up to 60W at 12 volts. Regards GG Superdad 1 Link to comment
