I intend to use this controller on a bilge fan rated 4.5 amp. Is OK to use?

It's rated for 10 amps so as long as the operating voltage is within 12 to 36 volts DC it should work for your application.

The specification states that it will control up to a 3 Amp fan. Check the amperage of the fan motors and add them, if the total is under 3 amps you should be OK. Most bathroom fans are well under one amp so it should run 2 or 3 without an issue.

Sorry, probably should of stated that the amps of the fan should match the amps of the switch. Oh the fan you r looking at has a temp control unit that has to be removed in case you did not know and if you want good suction u might want to go with the next size up the more cfm even the 2500 one kinda wish I got the better one

My guess is that the motor will draw to much amperage and overheat the regulator. Electronics pull very little amperage compared to motors. Good Day to you.

Maybe. Find out if the regulator will overheat with a 12V input. Probably better to use a 5V supply.

Can't answer that one for sure. You may want to check with the manufacturer. It would work when using the cooling unit at 15 amp and under.

No. I installed mine on a 20amp circuit bkr. When the fan motor and heater motor both run, at the same time, you'll need that extra 5amps to not "trip" out the feeding bkr..

Should not be a problem. It is a simple contactor which will shut the motor down immediately.Amperage is more than sufficiient.

I don't know why not, it is just a switch like any other. check the amp rating on the fans to make sure the total doesn't exceed the rating of the switch.

If the fans are 4 pin molex yes but you will need a splitter if you have more than 1 fan. If the fans are 3 pin your going to need a 4 pin to 3 pin splitter. As for the fan controller yes you can use this to power it as long as it has a 4 pin molex connector!

zzzzzz.... use your search engine. there are other fan controllers that allow PWM control but you will have to pay for the price

It draws 6 Amps, so I think you could. I don't recall what the CFM is on this blower. I installed 2 of them on my boat and they are working as expected.

No. This is a low power device, i.e. 2 Amps max, for small 120 VAC motors like overhead fans and such. I use it to control the speed of a small meat grinder, which it does well. It performs best with brush type motors and OK with small shaded pole type (as found in small appliances). A large house fan (e.g. 1 hp or so) like yours is a 240 VAC induction type motor which this kind of regulator will not work well on even if it could handle the power.

The 3 Amp should be a good choice to run that fan. I have a Vornado 510B (which is similarly rated) and I run it between 50-75% voltage to get absolute quiet operation and it works beautifully.

I had the same problem at the time determining the maximum current but I think most fans should be ok. I used it for a fairly large fan so I'm guessing most is good for most 15 amp circuits .

This motor should be fine for a fan motor AC replacement. The current draw is .3 amps more...that should be OK. You usually have to shorten the shaft.Not knowing exactly what condenser unit you are putting it in this is a best guess. Though, it should be fine...take care, Ross

It will physically fit.This controller is only 30 amp relay with a 30 amp fuse. If the electric fan set up you are using is higher amperage you can not use this controller.
