That fan is 24v because of it's internal resistancewhich is 120 Ohm's. Fans normally run on 12V (yellow + black), you can often get the desired result running them either on 7V (yellow + red) or 5V (red + black), without needing to burn extra power in a resistor. If you do end up needing a resistor, you'll probably just have to experiment since it depends on your needs and your fans. Output is opened collector and main board must have pull-up resistor to 12V. F1 = Fan cooling 1. On my setup, I have 24V Vin, but I only have 1 fan that uses 24V (extruder heatsink fan, so since it is an always on, it gets its 24V more directly from the power supply) - the rest are 12V fans as well as a 12V LED strip, these are run from a DC-DC Buck converter (input directly from the PSU), set to 12V and have this power fed into the Fan.

If you need 12V from 24V have a look at the LT1086 (you can buy it from Digi-Key). Because in a 12V LED strip there are 3 LEDs and a resistor in series, supplying 11V instead of 12V is a bit like reducing the voltage for each LED by 0. So, I happened to stop at Radio Shack for some other parts and discovered the clerk was a retired electrical engineer! Wow, I couldn't believe it- so I asked him how to wire a resistor to a 12V switch to use it with 24 volts. 1) A fan (5) can be connected between the terminals + and F. Signal Sense (tachometer) provides two pulses per revolution of fan. 5A fan to connect in series with the one you already have, you can try dropping the voltage using a resistor. Reduce the voltage to 12 volts by adding a resistor to the circuit. If the LED is made to run on 24V and you only have 12V you don't want a resistor in series to lower the voltage available to the LED - it is already way too low. Special promotion to get these with wonderful offer for cheap and shipping and delivery. There probably isn't a simpler way to pass the "Genuine Resmed?" test than using both components (fixed voltage source and fixed resistor, exactly as they provide in their own power supplies ). Many of the answers I read below are assuming two fans in series in the system. It is best choice for your product cooling. 2 out of 5 stars 53 $9. I need to reduce the voltage to 12V to power a water pump and to 5V in order to power an Arduino and an air pump. Just get a transformer to convert 24 volts into 12 volts.
