still waiting for startech. and need to get ready for the LPS. Below is layout.
Fanless pc (power : 6A, 12V) (need LPS)
cable : Split USB Cable (need LPS)
STARTECH LEX (power : 1A, 24DC)(need LPS)
cable: lan cable
to STARTECH REX (power : 1A, 24DC)(need LPS)
Split USB Cable (need LPS)
here, would use Holo Audio Titanis USB Turbo
1. this layout needs 5 LPS, any one box solution suggestion? Otherwise 5 power cords need to spend lot of money.
2. is the voltage fighure correct?
thank you very much.
Welcome aboard the Ultra USB train!
The Startech LEX needs 5VDC not 24VDC. That makes it much easier to find a LPS.
Here is what I use:
PC Seasonic Fanless High PSRR SMPS. This currently powers the MB/CPU and the one SATA SSD for the OS. I have a cable arriving soon to power the SSD from an ext LPS. So then only the PC will be on the Seasonic. It has it's own AC line isolation and filter unit.
The LEX is powered by a modded TeraDak X1/X2. This has two DC outputs one set at 5VDC(USB) and one adjustable that I will set at 5VDC also (DC plug) - one now on the LEX the second soon to power the SSD for the OS
The REX is powered by a MEIYAN ultra low noise 24VDC LPS
The Recovery (then to a iPur2 then to the F-1) is powered by a modded TeraDak DC-30W with a DC iPurifer.
So just three LPS's needed.
All this is spelled out on the opening page of this thread - worth a read. Post #7 goes into detail on the LPS's.
For more info on LPS's I have these three threads that go into detail on which transformer, regulation scheme and caps, etc... are best:
