Guys, i need a bit of advice on making a voltage/current regulator to run a few chargers for rechargeable torches at work.
The torches came from the US with 110v wall warts that power individual charging docks.
I want to run an Aussie 240v wallwart to power 5 of the charger units at the same time. The input requirements of the chargers are: 12v dc 500mA.
I got hold of an old ibm laptop power supply with a rated output of 16v and 3.36A.
Would it be possible to use this through a regulator of some sort to provide 5 outputs at 12v 500mA?
I am thinking of a voltage reg circuit using an LM317 but i am not sure how to go about the 5 x 500mA outputs.
I thought i could use the 317 circuit to provide the voltage drop and have it power 5 separate current regulators each set for 500mA.
I am assuming if i were to just put them all in parallel with no current control, whenever i took a torch out, the other chargers would get more than 500mA. Is this correct?
Any advice/recommendations greatly appreciated
Cheers
Gary
