I bought it for a totally different ... kind of silly reason.
I have those little 12volt 7watt & 11watt Malibu lights along my walkway.
I only have four currently active though and the combined load on the transformer is just under 3 amps. ( that's 36 watts right)
The thing is... I was using a 42 watt rated transformer/timer and it was really HOT to the touch.
I don't like going to sleep knowing things electrical are running THAT hot... even though I'm sure it's probably alright.
So I decided to upgrade to the next higher rated transformer of 88 watts. This model will handle up to 8 lamps at 11watts each.
Now you should know that a few years ago I also discovered that if I convert the 12vAC output to 12VDC using a full wave bridge and a 1000uf cap... the lamps last much longer than before on AC.
I used to have to replace these bulbs every couple months running 12 hours a day. ( turn on at 7pm and off at 7 am)
After converting to DC about a year ago I haven't replaced any bulbs yet ever.
So while browsing Ebay for a new 88 watt 12volt Malibu transformer I stumbled over this neat little 12volt 12AMP DC power supply for only $20 and $10 shipping.
So I bought it. It, of course is of the oscillator type that runs on both 220 or 110vac.
BUT... the rf noise is ZERO. I placed it right next to my AM radios and there is absolutely NO RF noise. Amazing.
In the mean time I did get an 88 Watt Malibu transformer and put a bridge in that one too. I certainly does run MUCH cooler than the 42 watt model but it does still feel quite warm
Today when this little 12VDC supple arrived I connected it to my lamps and tried it out.
It sure runs cool. You can hardly feel any head beyond the heat your hand my leave on metal.
Anyway here's were I got it in Hong Kong and thought that some of you guys might like it for your bench.

I'm curious, how do you get 12VDC with a 12VAC transformer and a bridge rectifier + e-cap ? Aren't you supposed to get around 15VDC (taking into account the diodes drop) ?
Also, using a 1000uf cap for a 3amps continuous current draw...wouldn't that stress the e-cap ?
Alas, the sale has ended. AVN, the cap doesn't care what the load is.
Lewis
There will be more sales I am sure.
As for the e-cap, I thought having excessive ripple caused by hi-current draw vs capacity would shorten the e-cap's life and even overheats it.
As I have said before, I worked on aircraft strobe lights, and we would charge to 375 or so Volts and discharge to 50 or so once a second, and they lasted or years. If one was leaking, now, you would either find the thing all over the inside of the light, or it would be very uncomfortable to hold.

Peter:
Doggone you! Due to this post, I got to wondering about my own Malibu lights, so this morning I went out on a little inspection tour. As a result, I have spent the whole day in 90 degree Georgia sunlight digging the lights out of the weeds and stuff. They clean up pretty good if you work at it. However, the clear lenses on the floodlights are getting yellow. Any suggestions how to make 'em clear again?
Lewis
I think you guys that repair CAR radios would love this power supply for your bench.

Lewis: I think it was Peter who successfully used a bleach soaking solution to remove the yellow from old plastic dial covers. I tried that with one of my radio's dial covers, and it didn't do any good. No harm, either.

:I treated them as if they were like a car finish, they had orange gookum on the fronts, so I rubbed them, polished them and finally waxed twice with Turtle Wax
:They are now almost clear, the light transmission has tripled. You would never guess they have been lighting up flowers in my front yard for nineteen years.
