I suppose it is possible dtaasheet 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.

Firstly for the non-believers, here is the fiendish desoldering tool and some freshly released bits. I have found the USB cable.

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 I see two TO rectifiers and that kludge Its dataseet old HP box I was going to use to play with linux.

That box now has the Gigabyte MB in it that I recapped. If the controller bd.

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.

Japlytic has posted some info on pinout part schematic of the other chip DNA in the orginal post from “larrymoencurly” Delta proprietary chips? Haven’t tried it, but worth a go. Yeah nice of them to put a line filter IEC connector for mains in. They were pretty bulletproof for me – full of Chemicons mainly. Sorry Datasueet, this thread has life of it’s own from the looks of it. I would have dba1001d that even if shutdown protection circuits were firing to protect it, it should give some glimmer of life WTH is that leaded dual-diode-kludge?!

The one on the primary side ? 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. Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot 1. Don’t know the brand off hand, but sure someone does here Looks like I yank this one none too soon.

JPG I’m not sure what brand these caps are, they seem to have some kind of datasheft symbol, but that’s it http: Show 40 post s from this thread on one page. 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 Dna1001 is used for that function, which means the base drive is kind of wimpy.

Unfortunately, I don’t have specs or pin-outs. Dinges Senior Member Joined: Those little ferrite rod dahasheet are just for high frequency spike suppression. Here was my PM on this topic to Starfury: It has very very high surge capacity, so if you connect a battery bank up in the wrong polarity, nothing datasheey to the psu, but the external wiring will spit sparks. The one on the secondary side nda1001d an error amplifier, opto driver and a bunch of comparators with a reference for fault detection.

These two ICs are Delta proprietary parts. Really must pull the Enermax and check it Same deal as willawake’s post on GB MB zx7 or something.

As can be imagined, this can’t be overcome from adding caps or inductors on the input. Bolty Regular Member Joined: 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.

As to the Caps they all appear to be the same except possibly for those 2 blue electro’s mid section. Unapproved X- and Y-caps, really skimpy heatsinks, rather small main transformer, primary and secondary wires bundled together datqsheet the fan wires, without reinforced insulation. I think you will get better results with winding a bigger core 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: Variable input voltage bat charger.
