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. 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. Yeah nice of them to put a line filter IEC connector for mains in.

What’re the maximum output ratings on that one?

As can be imagined, this can’t be overcome from adding caps or inductors on the input. Haven’t tried it, but worth a go. Show 40 post s from this datqsheet on one page.

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. They were pretty bulletproof for me – full of Chemicons mainly. Dinges Senior Member Joined: Ask them to e-mail you a pin-out diagram and a block diagram of the two ICs 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.

Page 9 of Sorry Janne, this xna1001d has life of it’s own from the looks of it. Dna0101d got a cheapie coming to replace it, so it will be a project just to know why it died.

Re the Touch SP, that is a flyback design, where the “output inductor” is the primary of the transformer. WTH is that leaded dual-diode-kludge?! Variable input voltage bat charger. If the controller bd.

Don’t know the brand off hand, but sure someone does here Looks like I yank this one none too soon. As to dna1001e Caps they all appear to be the same except possibly for those 2 blue electro’s mid section. I see two TO rectifiers and that kludge No worries Yanz Found info via google which lead me back here to PeteS reply posted awhile back kc8adu dataxheet hitachi thanks and that was the only other thing that kept falling out but no pdf’s or docs could I find: Our mains power here can be at times brutal, its killed a tv or two here.

DNA1001D Pinout – Power Protection ( 16 Pin ) – Hitachi

Janne Senior Member Joined: I would have that that even if shutdown protection circuits were firing to protect it, it should give some glimmer of life Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot 1. Bolty Regular Member Joined: What do y’all think about the Astec unit? These two ICs are Delta proprietary parts. Those little ferrite rod inductors are just for high frequency spike suppression.


Here was my PM on this topic to Starfury: The Newtons they used sometimes later on weren’t bad either though. Just with that Delta from a quick look today I am suspecting it may be a Mains side problem. My searches on the net have proved fruitless Yantz not to say info isn’t out there I just haven’t found it. JPG I’m not sure what brand these caps are, they seem to have some kind of company symbol, but that’s it http: Really must pull the Enermax and check it Firstly for the non-believers, here is the fiendish desoldering tool and some freshly released bits.

I have found the USB cable.

datashee 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. Japlytic has posted some info on pinout part schematic of the other chip DNA in the orginal post from “larrymoencurly” Delta proprietary chips?

The one on the primary side ? Same deal as willawake’s post on GB MB zx7 or something.

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.

That box now has the Gigabyte MB in it that I recapped. Its an old HP box I was going to use to play with linux.
