is a speed controller necessary in 12v application?

it was for me I want to run it in reverse at a low speed in the winter to circulate the heat from my fireplace and furnace,works great every room gets warm now,great product,hope this helps.

No, but of course the fan will only run a one speed. And BTW, I'm very happy with this fan. It draws very little power. The pricing is the problem here, I believe I could sell tons of these fans if the price was lowered to about $125...

I got mine upto 12.7 mph on 24v. The motors burned out. I've tried them all and the original PW motors hold up best.

If the controller is made for 12V fans, I don't see why not.. but I can not say for sure.. I don't know how they would fare if the voltage is limited..

You can use this controller for 12v but there will be power clipping. The best controller would be the Outback FM-80 for 1KW solar panels charging a 12v battery bank.Thanks, ML SOLAR

12v DC Commonly found on most Internet Routers will work, it is what im using on mine

Electronic variable speed with full feedback control for constant speed under load from 8,000-24,000 rpm and soft start to reduce start-up torque for enhanced control

The speeds ate set up like all 12 volts , we were not disappointed at all..

There are 12 speed settings. I bought it for my wife to replace a 20 year old Braun unit. She loves it!

This is a 12V. Fan, you cold apply 12v. directly (Ground and +12V.) and it will work at it's maximum speed (google "pc fan connector" to find out) The connector is: |Ground - +12v - Speed sensor - Speed control|However this is intended as a computer fan, i will not recommended it for any other use.

The circuit requires a driver capable of sinking 10MA. Most ucontrollers can do this. Since it is driven to ground no level shifting is required.

Not a problem at all. The controller regulates the voltage to 13 volts since that is the most a 12 volt system can handle.

P=IV. I=320W/24V = 13.3Amps. So a 25A motor controller will be fine. There are many input modes for the motor controller if you use analog mode 2.5V will be off, 0 V will be full reverse. 5V will be full forward. There should not be an issue with no ramp up, its not the best on the motor, etc. but the motor controller should handle the current base on what you have specified.

I used a relatively cheap controller from china good for 30 amps and 12vdc (requires a reversing switch). I ran a 100 volt dc motor with a full wave bridge rectifier (cheap from Radio Shack)and a variable transformer and it did a good job for speed control for the carriage feed on a bandsawmill that I built. Hope this helps..

If the purpose is to use it as a speed control, I don't see why not except if the amperage of the motor exceeds the capability of the dimmer. This 12v dimmer is designed for low load LED lights. If you have a high load fan, like more than 1 amp, then probably not.

Yes. I hooked it up to an Arduino that controls the voltage to the motor (using a transistor) to vary its speed.

To the best of my knowledge it is intended as a battery maintainer for 12 V. batteries either starting or deep cycle. It's low output does not require a controller.

That would depend on the motherboard I think. It uses a 3 pin connection, but only two wires. The voltage would have to vary in order for the speed to vary. I'm not familiar with how those controls work, so I can't say for certain.
