Koralia Speed Control...A DIY Idea/Question

[TheBluefish]

Hey Gang

I have an electrical question today. I picked up two (Koralia Evolution 1050 Circulation Pumps) and a (Reefkeeper Lite) for my new tank build. I was wondering if it is safe to plug them into a regular outlet/plug that is controlled by a (Slide Dimmer) like one you would use for a light in your house. The idea is I would be able to turn down the pumps but still control the on and off timing with the Reefkeeper without having to buy a new/different controller for another $100. Please see the illustration below. I would be wiring this in the normal wall jack box with a faceplate in my stand. Let me know if you think there is a problem with controlling the Koralias output this way.

Many Thanks!
Nick

I'm not sure about problems really, but it could take a toll on the motors as they are designed to have a constant amount of power supply powering them. The way a slide dimmer works is it adjust the power that is going to the light bulbs. Same thing here, although I am not sure if the koralias can handle that?

+1 on unknown stress on impellers.may freeze up in time

also, Nick the vodka is for the tank,not for drinking and inventing new korrallia projects on your cad program

Thanks Gang. Looks like its going to be an experiment...:wavey:

you're going to blow up the controller... make sure it can handle the amps of the pumps...

i thought you were going to get an electronic/programmable potentiometer...

Dude each one is only 5 watts and the controller doesn't pull any weight only the DC4 does. +1 on the potentiometer. The dimmable switch was easier but something to think about.

hmm... after researching the pumps... this might work...

but... i wouldn't use a wall dimmer... i would get a built in dimmer receptacle... when rewireing my pad, i found them and thought about getting them for like my room and bathroom...

it has an outlet and a touch/slide dimmer in the same one... instead of having two of them...



oh... and it will work... but i don't know if you're going to need diodes or rectifiers to keep the pumps from starving... or i don't know since they are made for wavemakers they probably have them built in...




hmm...






i think it should work...

good luck...
