My searches on the net have proved fruitless Yantz not to say info isn’t out there I just haven’t found it.
It has very very high surge capacity, so if you connect a battery bank up in the wrong polarity, nothing happens to the psu, but the external wiring will spit sparks. Firstly for the non-believers, here is the fiendish desoldering datashert and some freshly released bits.

Bolty Regular Member Joined: As to the Caps they all appear to be the same except possibly for those 2 blue electro’s mid section. Those little ferrite rod inductors are just for high frequency spike suppression. That box now has the Gigabyte MB in it that I recapped. Japlytic has posted some info on pinout part schematic of the other chip DNA in the orginal post from “larrymoencurly” Delta proprietary chips?

Janne Senior Member Joined: The Newtons they used sometimes later on weren’t bad either though. Sorry Janne, this thread has life of it’s own from the looks datasheet it. The one on the secondary side contains an error amplifier, opto driver and a bunch of comparators with a reference for fault detection.

Don’t know the brand off hand, but sure someone does here Looks like I yank this one none too soon. No worries Yanz Found info via google which lead me back here to PeteS reply posted awhile back kc8adu mentioned hitachi thanks and that was the only other thing that kept falling out but no pdf’s or docs could I find: Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot 1.
JPG I’m not sure what brand these caps are, they seem to have some kind of company symbol, datashest that’s it http: Unapproved X- and Y-caps, really skimpy heatsinks, rather datasheett main transformer, primary and secondary wires bundled together using the fan wires, without reinforced insulation.
The outer shell kind of gave it away, but this, probably for datashheet th time, reinforces the fact that Fujjy’s are far too unreliable to be recommended.
Here was my PM on this topic to Starfury: I would have that that even if shutdown protection circuits were firing to protect it, it should give some glimmer of life Anyway got a cheapie coming to replace it, so it will be a project just to know why it died.
I have found the USB cable. What’re the maximum output ratings on that one? The one on the primary side ? Our mains power here can be at times brutal, its killed a tv or two here. They were pretty bulletproof for me – full of Chemicons mainly.
Just with that Delta from a quick look today I am suspecting it may be a Mains side problem. Dinges Senior Member Joined: Probably uses clones of Motorola’s MJE or MJE bipolar transistors, with no DC-blocking cap to keep the transformer core from walking into saturation due to slight pulse width variations. Unfortunately, I don’t have specs or pin-outs.
The smaller of the two transformers fna1001d base or gate drive; no obvious drive transistors, so the internal drive of the PWM is used for that function, datashset means the base drive is kind of wimpy. My suggestion would be to send an e-mail to Delta’s Sales and Support office, either in the UK or the US which can be found on this webpage. Yeah nice of them to put a line filter IEC connector for mains in.

I suppose it is possible that a choke will help filter out the harmonics, but I can’t see it correcting the crest surge by much for a 50hz choke of reasonable size. Show 40 post s from this thread on one page.
These two ICs are Delta proprietary parts. Page 9 of I think you will get better results with winding a bigger core I see two TO rectifiers and that kludge Ask them to e-mail you a pin-out diagram and a block diagram of the two ICs If the controller bd.
Variable input voltage bat charger. Haven’t tried it, but worth a go. Re the Touch SP, that is a flyback dafasheet, where the “output inductor” is the primary of the transformer.

As can be imagined, this can’t be overcome from dnz1001d caps or inductors on the input. Its an old HP box I was going to use to play with linux. Same deal as willawake’s post on GB MB zx7 or something. Really must pull the Enermax and check it What do y’all think about the Astec unit? WTH is that leaded dual-diode-kludge?!
