I'm using a 12V marine battery to power a bilge pump (4.8 amps @ 12 volts). Can i use this PWM controller to vary pump speed?

I cannot say for sure since I don't know enough about your pump, but I think it would work. I use this to control the speed of a 12V, 6A motor and it works very well.

It can run small motors, I use one myself to slow the flow output from 12 volt bilge pumps. Have yet to have one let me down yet.

Your float turns a switch on and off on or near the motor. If you can lock the switch in the on position (many options), and your pump runs full time, you can use this switch by plugging it into the outlet first and then plugging the sump line into the control. Directions aren't the best but mine still works. Good for up to 14 amps. I'm always cautious with low stock items. They could be returns but Amazon backs up their products.

This item contains a 12 volt washdown pump. It is not boat specific. It will work with any boat with a 12 volt dc battery/power supply.

I bought mine a year ago and have been using a standard 12 Volt battery in my boat. Never had a problem and it does it all. I use it to steer my ipilot troweling motor.

Your controller can only deliver as many watts as your motor can draw. Your can always use a controller that allows higher wattage, just not higher voltage.

I dont see why not. I am using on a 12 volt sustem for my sailboat. My battery bank is 880 amps

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

Assuming you make the proper connections, the switch should do fine on a 12 V battery pump. My battery pump has the same float switch and is rated for 10 Amps at 125V.

Im not sure how many amps it is rated for. I use it on a 12v marine deep cycle battery systme.

I used it to control a 12v powered water valve remotely. Probably depends on the amp draw of your setup ... but if it was a higher draw than the remote handled directly, just put a 12v relay in the path to handle the amps/

Sorry Grandor for slow reply but I can not say for sure if the controller could handle the constant current draw for a pump. April 01, '14.

The switch will work fine for the generator battery - it will actually be overkill in that application. The switch intended application carries the full current of a marine battery to a large starter motor - which is over 100 amps ....and up to the full 500 cold cranking amp capability of a marine battery.

If these pumps are 12V, what do you need this PSU for? Just buy a suitable 12VDC power brick and be done with it. Adding this into the mix is unnecessary, assuming that you've described the intended application correctly.

I am not an expert by any means, with regard to the application you describe above, however ;my experience with this PWM, while hooked up to a heavy duty 12 Volt car battery and a Hydrogen producing cell block; performs the VERY same as a Rheostat normally would. I have yet to hook it up to anything below12v(such as the 3.90 A 12 volt power source you mention) and see what results I can get.

Hi There I run the inverter off of a 27D size 12 volt battery on my boat that is charged from a 120 amp alternator off of the motor.

i'm not sure...it's just a regular plug-in 120v...you may need to contact Marineland company for specifics!! Sorry!!
