Re: 200v 30a Rectifier
These power supplies were butchered by the previous Tech or whoever tried to repair them. There is a voltage divider section that has been moved off the main board entirely. The 339 circuit is giving me fits on what it wants to see Voltage wise before it will enable.Comment

Re: 200v 30a Rectifier
"Rectifier" in this context may be telecom-lingo for power supply. Based on the large number of Wima, Roederstein, and, possibly, Siemens film capacitors, I'd guess it's a European product, possibly Russian.

Re: 200v 30a Rectifier
I believe the unit is German. Here are some better pics. I managed to get a few of them to run . On the others I'm having a hard time getting the opto to fire.
Thanks in advance for any advice .Attached FilesComment

Re: 200v 30a Rectifier
I do believe Gramm Analagentechnik GmbH is a German company
I entered "galvamaks" into google translate and it detected the language as Latvian and the translation was "headache" seems fittingComment

Hi all, a newby question about a bridge rectifier I'm trying to identify.
I'm in the midst of reparing a battery charger in work which went pop, The bridge rectifier has shorted and took out a couple of other components. The rectifier in question has a part number KPB305G, and it looks like it's obsolete. Does any one know what I could replace it with?... -
Hello everyone,
I'm trying to fix up my battery charger. Where I found a dead schottky rectifier.
This is the dead component PTR30L120CTF:
PTR30L120CTF datasheet(1/7 Pages) PFC | 30A 120V HPTR Schottky Rectifier (alldatasheet.com)
And I have a spare 30CPQ150:
30CPQ150 datasheet(1/5 Pages) IRF | SCHOTTKY RECTIFIER (alldatasheet.com)
Can I use this diode as a replacement or if not, can you recommend me a proper replacement?
I cannot find the exact unit anywhere besides aliexpress and such.
Thank you guys!

For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
http://www.rmac.kingwin.com/products.../abt_650MM.asp
I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.
What mostly drew me into buying it is its 2x PCI-E power connectors... -
Hello
My Fujitsu Esprimo Q556 motherboards blew up. At least fuse, bridge rectifier and capacitor got damaged. I have changed fuse and bridge rectifier (DF1508S), but I don't know what capacitor it is (picture). I know that capacitors size is 47nF, but I don't know other specs for it. Can you help me to choose right capacitor for my motherboard?
There is 240V AC on input side of bridge rectifier and 340V DC as output on capasitors side.
Thanks.... -
I had my Quadra 840AV (which I recapped and had working) plugged in for some time without using it and randomly decided to turn it on today. Unfortunately it did not turn on. After checking the PSU, I found out I was not getting anything from 12V, only from the 5V rail. After a few minutes, I removed the PSU and plugged it back in the electrical outlet and it suddenly started making a weird sound and soon after smoke started coming out. I quickly unplugged it. I opened it up but on first instance I didn't see anything out of the ordinary really. I later turned it back on and one of the MOVs blew...12-22-2024, 05:07 AM
