soft start for powerhead

[titus]

Hello Darren,

Sometime after my thesis is good. Whenever that is.

Gord,

I try not to read the article and get too involved in this. But my guess of the choke is just a simple inductor to prevent rapid current spike due to a step function for the voltage input. Yes it'd work but won't provide the level of sophistication of using a controlled current driver.

Troy,

Yeah just as I thought what the commercial hobbyist wavemakers are. But I wonder what the public aquariums use. Isn't that why we started this thread? Oh well it was a while ago so I forgot about it.

Hey I keep hearing these Tunze stuff from time to time. It always seem like they have very neat design. But you are right, powerhead are cheap. I was discussing with John and J&L about the reliability of Eheim pumps, which is supposed to be the best by the way, and me, him, and Precison Marine all agree that there are problems with these guys.
