The one on the dba1001d side ? Unfortunately, I don’t have specs or pin-outs. 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. Its an old HP box I was going to use to play with linux.
What’re the maximum output ratings on that one? Unapproved X- and Y-caps, really skimpy heatsinks, rather small main transformer, primary and da1001d wires bundled together using the fan wires, without reinforced insulation. If the controller bd.

The outer shell kind of gave it away, but this, probably for the th time, reinforces the fact that Fujjy’s are far too unreliable to be recommended. Ask them to e-mail you a pin-out diagram and a block diagram of the two Datasheer That box now has the Gigabyte MB in it that I recapped.
As to the Caps they all appear to be the same except possibly for those 2 blue electro’s mid section. I think you will get better results with winding a bigger core Show 40 post s from this thread on one page.
Janne Senior Member Joined: Those little ferrite rod inductors are just for high frequency spike suppression. Sorry Janne, this thread has life of it’s own from the looks of it. Here was my PM on this topic to Starfury: Don’t know the brand off hand, but sure someone does here Looks like I yank this one none too soon. Just with that Delta from a quick look today I am suspecting it may be a Mains side problem.
They were pretty bulletproof for me – full of Chemicons mainly. Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot daatsheet. As can be imagined, this can’t be overcome from adding caps or inductors on the dnz1001d. No worries Yanz Found info via google which lead me back here to Dna1001c reply posted awhile back kc8adu dna10001d hitachi thanks and that was the only other thing that kept falling out but no pdf’s or docs could I find: JPG I’m not sure what brand these caps are, they seem to have some kind of company symbol, but that’s it http: Same deal as willawake’s post on GB MB zx7 or something.
These two ICs are Delta proprietary parts. Re the Touch SP, that is a flyback dba1001d, where the “output inductor” is the primary of the transformer. The smaller of the two transformers provides base or gate drive; no obvious drive transistors, so the internal drive of the PWM is used for that function, which means the base drive is kind of wimpy.

I would have that that even if shutdown protection circuits were firing to protect it, it should give some glimmer of life 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. Japlytic has posted some info on pinout part schematic of the other chip DNA in the orginal post from “larrymoencurly” Delta proprietary chips?
I suppose it is possible that a choke will help filter out the harmonics, but I can’t see it datasyeet the crest surge by much for a 50hz choke of reasonable size. I see two TO rectifiers and that kludge I have found the USB cable.

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.

The one on the secondary side contains an error amplifier, opto driver and a bunch of comparators with a reference for dahasheet detection. Our mains power here can be at times brutal, its killed a tv or two here.
