DSS220 I've had a few, and a couple of motherboards.  |  IP: Logged Jason Raftery Film Handler Posts: 72 From: San Diego, CA, USA Registered: May 2011 posted 01-18-2016 06:39 PM                     The Supermicro P/N for a DSS200 power supply module is PWS-801-1R. I don't have any 220's so not sure if they use the same module or something different.  |  IP: Logged David J Hilsgen Expert Film Handler Posts: 192 From: SAUK RAPIDS,MN .

Posts: 3686 From: Dallas, TX Registered: Nov 2000 posted 01-19-2016 01:07 PM                     Dolby DSS200 - Ablecom PWS-801-1R (800w) Dolby DSS220 - Ablecom PWS-702A-1R (700w) The 800w unit will also work in the 220, but the 700w unit will *not* work in the 200.  |  IP: Logged Aleksandar Obradovic Expert Film Handler Posts: 125 From: Belgrade, Serbia Registered: Oct 2012 posted 01-19-2016 05:51 PM                     Hi guys, Like Mark said I think that it would be the best way to open broken PSU and then test and replace failed parts (of course if your warranty expired). Best part of it is that you can find components in your local store for a few bucks (top) and in that way you can learn something more or at least stay in shape with soldering iron Alex  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 12-21-2017 08:47 AM                 It has been 701 days since the last post.  |  IP: Logged Ian Garland Film Handler Posts: 23 From: oswestry, shropshire, UK Registered: Sep 2014 posted 12-21-2017 08:47 AM                     Just had one of othe PSUs on our DSS200 die this morning. Have ordered a new Ablecom PSW-801-1R but out of curiosity have stripped down the failed unit and on visual inspection U1 on the main board has popped it's clogs. Have tried searching for schematics online but to no avail. Trouble is the blown chip has a nice hole at the end of the part number so all I have is that it is a Power Integrators device TOP2 --N to go on. Anyone have the part number to hand or has a unit they can take a peak at?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 12-21-2017 09:38 AM                     The DSS200 always has two supplies. Why not look at the other one?  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 12-21-2017 10:18 AM                       I don't know if it's a good idea to take apart the one good supply to try and fix the bad one. These are quite cheap supplies so I'd order a new one and be done with it. I have quite a few in stock and I got them the same place as everyone else.  |  IP: Logged Adrian Avram Film Handler Posts: 45 From: Iasi, Romania Registered: Oct 2013 posted 12-21-2017 12:57 PM                     U1 on these power supplies is TOP244YN fully integrated IC with Control + power Mosfet for up to 45W from Power Integrations  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 12-21-2017 03:21 PM                      |  IP: Logged Ian Garland Film Handler Posts: 23 From: oswestry, shropshire, UK Registered: Sep 2014 posted 12-22-2017 04:32 AM                     Thanks all and Thanks Adrian, just what I needed. part on the way and at £3.24 a lot cheaper than the north of £200 spent on the replacement PSU. hopefully will have a good spare to keep on the shelf now. Really should screen that film some day...  |  IP: Logged
