Hi,
I have a really simple circuit. the l317 Current limiting with 1 L317 and 1 resistor. It's the basic circuit you can find everywhere on the net.
The LM317 Current limiting circuit is set to about 1 amp with 1ohm resistor (I use 2x 0.5 ohm 2watts resistors in serie).
When I plug it to a 12volt wall-wart power supply it works well .. when I short the 2 leads I get something around 1amp...
But when I plug this to my 24 Astrodyne Power supply (SP-320-24) I get nothing more than 0.010amp ... even If I short the leads I get no more .. The power supply is rated at 13A and It gives 13A trust me.
Is this because the astrodyne is a switching power supply (Fixed switching frequency at 100KHz)
If someone can help me with this I will appreciate .. I hope I'm clear enough.
