Default 12 V Power Supply ?


Hey guys,
My trusty 20 year old Motorola power supply I use on my workbench has finally decided it has had enough. I may take it apart this weekend and see if I can fix it, but I really need one with a little more output. 30 amps would be my choice.

So what is everyones preference ? I dont need bells and whistles, just reliable, clean 12VDC. Does not have to be adjustable and I dont really care if it has a meter or not, thats what the DVM is for I would prefer the output connector on the front, my present one is on the back of the unit.

Any thoughts ?

This thing is cheap and clean power, more than does what you need it to do. For the price you should really consider it instead of messing with fixing, or rebuilding your other one. best of all this thing takes up next to no space

FX,
Am I looking at that thing correctly and seeing the AC input connectors exposed ???? No thanks.

That being said, I started searching for info on my Motorola and it turns out it is an Anstron RS 10 with a Motorola Decal on it. I figure I have had it for close to 20 years and it was used when I got it so I think another Anstron might be the way to go. The RS30 is 25 amps continuous and 35 peak, that should do anything I need.

Any word on the newer Anstrons ?

Owning and using one of these units, I see no difference in safety between the way the AC is connected to this unit compared to any other, bannana plug or otherwise. And the ratings on eHam are the highest of any other power supply.

I am trying to invent an mathematical formula that can be used to convert EHAM reviews into real world numbers.

I don't care rated it. It's a decent, cheap, clean working unit. I ran a 4 x 1446 amp and a SSB mobile CB off this very unit, not even a 10th of a volt power

As for the AC power in connection, you could open it up and make it take a standard 3 prong plug, like out of a computer of something.

I plan to install mine in a new case and maybe install a larger slower moving fan and better connectors.

Sometimes we need to go with the information we got.

I realize you were joking, but...

Try this formula: Average rating divided by 1 plus the percentage below the median price of of all similarly purposed items. If the price of the item of interest is $65, and the rating is 5.0, divide 5.0 by the 1 + % below median price of all 30 amp continuous units. Assuming the median price of all 30 amp units is $120, divide the rating of 5.0 by 1.5 giving it a rating of 3.33.

This will subject the outrageously cheap units to a reality check of why they are so cheap - that considers their lack of features or other qualities that more expensive units have.
