wiring a thermostat question

[northdakotaoutfitting.com]

i know how to wire it i need to put less current to the fan so i dont burn it out. i will never in a 100 year be able to hook it up the way your drawing is unless i have some sort of power converter.

i got my incubator all wired up except for a fan, i have a small computer fan 12v DC 0.18A and i was thinking of using a 12v cell phone charger since it has a converter built in it. do u think i can use one thats 12V 1.5A or do i need a smaller one to run this fan or is there another way to rig it up?

That will work ok. The voltage rating should be the same, or fairly close. The current rating (amperage) of your power supply needs to be equal to or greater than the current requirement of the device you want to power.​

so it wont burn it out since its a 12v 1.5 amp? the fan is only 0.18 amps though. im not big on wiring so thats why i question this, just seems like its to much amps going to a small fan that says 0.18 amps on the back of it

Think about this way. A wall outlet is a 120 volt power source that has a capacity of 15 amps. You would plug in a 120 volt appliance(s). That appliance, or combination of appliances, may draw 1, 5, 10 , or even 15 amps. As long as you do not exceed the capacity of the power source (in amps) you are ok.

You power source has a 1.5 amp capacity. You could actually run multiple .18 amp fans from that source, but 10 fans would draw 1.8 amps and would exceed the capacity of your power supply.​

You may have already got a reply, but this is what I did with both of my homemade incubators.

The non-wired side is the black wire or the positive wire, the side wired to the thermostat is the negative side.


Hope this helps.

ok wait a minute, my power source is going to be the wall outlet. if i do this right i can take that cell phone wall charger thats 12v 1.5 amp, cut the one end off, wire the fan to the other end and should be able to plug it in to the wall and it will work right?

Yes, if your cell phone charger is 12V DC, 1.5 A and you are running a 12 volt DC fan that draws .18 amps, you can cut off the connector that goes to the cell phone, wire it to the fan observing the correct polarity (positive to positive, and negative to negative), plug it into the wall and the fan should run. If it doesn't work, or runs backwards, you may have the polarity reversed.​

ok ill give it a try thanks 4 clearing it up
