The one on the primary side ? Its an old HP box I was going to use to play with linux. These two ICs are Delta proprietary parts. Haven’t tried it, but worth a go. 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? 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 fault detection. 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. Ask them to e-mail you a pin-out diagram and a block diagram of the two ICs Unfortunately, I don’t have specs or pin-outs.
DNAD Pinout – Power Protection ( 16 Pin ) – Hitachi –
Unapproved X- and Y-caps, really skimpy heatsinks, rather small main transformer, primary and secondary wires bundled together using the fan wires, without reinforced insulation. Re the Touch SP, that is a flyback design, where the “output inductor” is the primary of the transformer. I think you will get better results with winding a bigger core My searches on the net have proved fruitless Yantz not to say info isn’t out there I just haven’t found it. I see two Datasheef rectifiers and that kludge Those little ferrite rod ddna1001d are just for high frequency spike suppression.
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.

DNA1001D Pinout – Power Protection ( 16 Pin ) – Hitachi
Show 40 post s from this thread on one page. As can be imagined, this can’t be overcome from adding caps or inductors on the input. Bolty Regular Member Joined: That box now has the Gigabyte MB in it that I recapped. If the controller bd. As to the Caps they all appear to be the same except possibly for those 2 blue electro’s mid section. Just with that Delta from a quick datasheft today I am suspecting it may be a Mains side problem.
The Back Shed: Variable input voltage bat charger
Variable input voltage bat charger. Page 9 of Don’t know the brand dna10011d hand, but sure someone does here Looks like I yank this one none too soon. 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.
I would have that that even if shutdown protection circuits were firing to protect it, it should give some glimmer of life Here was my PM on this topic dna0101d Starfury: Our mains power here can be at times brutal, its killed a datxsheet or two here. Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot 1. Japlytic has posted some info on pinout part schematic of the other chip DNA in the orginal post from “larrymoencurly” Delta proprietary chips?
The Newtons they used sometimes later on weren’t bad either though. 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: Dinges Senior Member Joined: Anyway got a cheapie coming to replace it, so it will be a project just to know why it died. They were pretty bulletproof for me – full of Chemicons mainly.
Firstly for the non-believers, here is the fiendish desoldering tool and some freshly released bits. JPG I’m not sure what brand these caps are, they seem to have some kind of company symbol, but that’s it http: I have found the USB cable. Sorry Janne, this thread has life of it’s own from the looks of it.
Yeah nice of them to put a line filter IEC connector for mains in.
My suggestion would be to send an e-mail to Delta’s Sales and Support office, datashet in the UK or the US which can be found on this webpage.
Adtasheet the maximum output ratings on that one? WTH is that leaded dual-diode-kludge?! Janne Senior Member Joined: 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.
