Bolty Regular Member Joined: JPG I’m not sure what brand these caps are, they seem to have some catasheet of company symbol, but that’s it http: Those little ferrite rod inductors are just for high frequency spike suppression.
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.
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. Page 9 of As can be imagined, this can’t be overcome from adding caps or inductors on the input. Re the Touch SP, that is a flyback design, where the “output inductor” is the primary of the transformer.
Haven’t tried it, but worth a go. 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. Here was my PM on this topic to Starfury: I think you will get better results with winding a bigger core They were pretty bulletproof for me – full of Chemicons mainly. 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.

What do y’all think about the Astec unit? The one on the primary side ? As to the Caps they all appear to be the same except possibly for those 2 blue electro’s mid section. Sorry Janne, this thread has life of it’s own from the looks of it. Don’t know the brand off hand, but sure someone does here Looks like I yank this one none too soon.

I see two TO rectifiers and that kludge If the controller bd.

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. 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: Just with that Delta from a quick look today I am suspecting it may be a Mains side problem.
Firstly for the non-believers, here is the fiendish desoldering tool and some vna1001d released bits. Looks like a bigger version of the w ones Astec built for Gateway midtowers late socket 7 and slot 1.
Same deal as willawake’s post on GB MB zx7 or something. Our mains power here can be at times brutal, its killed a tv or two here.
Janne Senior Member Joined: WTH is that leaded dual-diode-kludge?! 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 datashet wimpy. Yeah nice of them to put a line filter IEC connector for mains in. Show 40 post s from this thread on one page.

What’re the maximum output ratings on datazheet one? I have found the USB cable. 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.
