Strange Power Supply in SE/30
Posted by: joethezombie on 2016-12-19 18:29:53
I've started recapping the power supplies and analog boards in my SE/30 collection.  One of my Macs has which I can only surmise is a 3rd party power supply:

This seems to have nearly twice the output on the 12V rail (5.0A) vs. the official power supplies Apple supplied (1.25A sweep, 2.1A disk).  It's also switchable between 115V/230V.

Anyone in the know on 3rd party power supplies?

I dug up a tiny bit more info on this guy from Usenet.  I'm assuming it to be the Power Plus Systems upgrade, due to the model number "PPS-101" and the "Made in the USA" stamp.


Subject: Info wanted: Upgrading SE/30 power supply
 
Hello Netter,
 
I want to uprade the power supply of my SE/30 in which a 8 bit color card is installed. I know CRC COMPONENTS, Inc. deals the compatible power supply of SE/30 manifactured by POWER PLUS SYSTEMS. Does anyone know their phone or FAX number of them ? Please reply me by e-mail.
Thanks,

Q•Where can I purchase third-party power supplies for the Macintosh?

A. I know of only two companies that currently manufacture replacement Macintosh power supplies: Quadmation and Power Plus Systems (PPS).  Recently I had an opportunity to evaluate and benchmark power supplies from both companies. Being an expert in electrical engineering and design, I really put these units through their paces. The results were mixed. The Quadmation flex power supply I evaluated performed worse than Apple's. My Mac would not come on and stay on. Their technical support was unfriendly and not very helpful. When I inquired how to return this power supply for a refund, I was given a hard time. I would be surprised if the unit they shipped me would pass either UL or FCC certification.  The second company I evaluated was Power Plus Systems in Salt Lake City, Utah. I evaluated their Ilcx/IIci/Quadra 700 power supply in the same manner as I did the Quadmation unit. The Power Plus unit was superior in every way to both the Quadmation and the Apple unit. I got at least twice the power of the Apple model at one half the price. When I had questions, they answered them promptly and intelligently. The president, Craig Rosenthal, even got on the line to see how I liked the unit. (He didn't even know me!) They also have a very generous two-year warranty. Double thumbs up to Power Plus Systems. You can contact PPS at 1-800-722-0602.
 
so that's neat, but is all the information I could find.
