Transformer Trouble

[leesichello]

Hi,
Im have two computer fans wired in parallel right now, the specs on them say .3 amps at 12 volts. They are connected to a transformer that puts out 1.5 amps at 12 volts and im not sure if this is safe. Should i have a transformer that runs closer to .6 amps or am i okay as is?

As long as the "transformer" puts out 12 volts DC, then you are OK. The fans will only take the amount of current that they need at 12Vdc.

i dont need to worry about frying the wiring from too much current?

Wires fry when the current in them is too high. Look in Google for a table of wire sizes. A little current of only 0.6A can use a little wire size.

You won't get too much current.

The transformer rating of 1.5 A is the maximum. It does not supply 1.5 A unless there is somewhere for it to go. It supplies 12 V. You can take any amount of power from it that you want up to 1.5 A.

A cigar lighter socket in a car supplies 12 V. It is rated at 20A because it has to be made so that it can heat a cigar lighter. When you don't use it no current is supplied. When you plug your cellphone charger into the socket, the charger takes maybe 0.25 A which is fine because it is less than 20 A.
