Electric fan help

[Wayne]

Hey I am building a canopy for my tank which is going to have 2 electric fans. The fans are 12V, 50/60mhz, 0.24mA. I am wondering what kind of transformer I need to find so I can plug these bad boys in. Perferably wired in parallel with one tansformer. Thanks

Are you sure about the amount of current drawn? It just seems too small for most fans I've seen. Are those ac fans by the way or dc?

[Wayne]

Thats what is on the lable. I believe they are DC. They are about a 5" computer fan.

There is something wrong in the label.

At a Frequency of 60 mega hz/second, only IC or... can see the pulse. For the fan? It looks as if as dc.
Again, at a currency of .24 mA (1/1000 Amp) a fan can not even make a turn ( a LED consumes a lot more than that.)

So, i think this label belongs to an IC chip or ...

Suppose it is 12v .24A. then each fan is about 3w. For parallel connection, you need a minimum 2x3w=6w transformer.

Therefore, a 10w 12v DC Transformer is good enough.

Go to the Value Village or Thrift Store buy two AC to DC transformers; one with 12v-10w and the other with 9v-10w.
Try the 12v first. If it is too noisy, try the 9v then.
They are cheap, under $5 each.

For a DC fan about htat size, .24A (not mA) sound about right. Computer speaker power supplies are usually 12V and big enough.

It's too bad your not closer -- I have a box of 12VDC 1A transformers that I use for fans and LED drivers that I give away to anyone that needs them

Hum I very well might be wrong about the mA. I will have a look at the few transformers I have (from various phones, motors...) if not now I know what to look for. Can I try Radio Shack?
