I have recently acquired a number of these.
They are AC powered by IEC lead.
They appear to use two types of open frame PSU
These are;
AstecAE-24-1200 and
Alimeko/Rev UK - believe to be made in house by Lacie (bears a D2 logo).
The first of the two is found in a SBC SCSI Controller housing.
It has a rated O/P of +12V @ 1.0A, +5V @ 4.75A
It is populated with Chemicon LXF in the O/P filter
The ESR of these read ok but the date code of the PSU is 9648.
I assume this is 1996 week 48
As LXF have a purported endurance of over 8k hours and more, I
believe replaceing these LXS (replacements for LXY)
or another alternative such as Pana FC is the correct course of
action.
Sorry no pics. Any comments?
The second PSU is a little less well featured as it is used to
power optical and tape drives and possibly single HDDs.
The PSU inside of a CD-R unit appears physically, to be ok.
However, the same PSU in a Sony DDS-2 tape unit has
the primary cap starting to physically dome.
The primary has a Siemens 400V 47uF and a REC 47uF 16V.
The bad Siemens cap has an ESR of 1.2, the REC in the same PSU, 2.3.
I guess this appears to be a failure area in these, the second PSU.
Both of these PSU have a date code of 1998.
The O/P filter for these second type of PSU have Sanyo SE
(1 of 1000uF 16V, 1 of 470uF 10V) and what appears to be
Pana CE 85 deg C 100uF 16V (2 of)
The Sanyo ES have ok ESR (cannot find the datasheet) and
the Panas are about half an ohm or so.
Q - Replace with better series such as Pana FC?
Your insight apprecaited
Thx
