fishmanmike01 Posted March 23, 2017 Share Posted March 23, 2017 I'm trying to understand what's going on with my WP pump converters. I've gone through 4 of these in just as many weeks. Pumps run at constant speed. My problem is I find them pulsing and if I replace the converter if seems to fix if for a short time only to find them pulsing once again. Anyone experience this before? Is the problem the pump itself? Quote Link to comment Share on other sites More sharing options...

cjmdh Posted March 23, 2017 Share Posted March 23, 2017 Yes, I have some Chinese LEDs and one of the power supplies caused the lights to flicker. Swapped power supplies and it quit. Not sure what the cause is. Quote Link to comment Share on other sites More sharing options...

I have gone through a few over the years too on the return pumps. Frustrating. I found a place that has them cheap on amazon and ordered up a few spares. https://www.amazon.com/Minger-Supply-Adapter-Transformer-Flexible/dp/B01AJQ9G2C/ref=sr_1_3?ie=UTF8&qid=1490279258&sr=8-3&keywords=24V+6A+Power This is one of the weaknesses of DC pumps IMO... reefbreeders sells the OEM ones too. Where did you pickup your replacements? Quote Link to comment Share on other sites More sharing options...

Where did you pickup your replacements? Thanks for the heads up Jeremy. I had extras from other pumps. Just curious if others have had the same issues. I was starting to think it was the pump causing the failures but it's looking like it is the modules. Quote Link to comment Share on other sites More sharing options...
TheClark Posted March 23, 2017 Share Posted March 23, 2017 No problem Mike. That does seem like quite a few failures, so if you keep going through power supplies perhaps the controller or the pump has issues. Quote Link to comment Share on other sites More sharing options...

TheClark Posted March 24, 2017 Share Posted March 24, 2017 Cool keep us posted. I am running 4 of the various dc 12000s around here now. Great pumps... Had another thought. Your mounting is slick, very nice. One thing to consider... heat can be a factor with power supplies. If you can get a spacer behind them that will give em a little more room to dissipate heat.

fishmanmike01 Posted March 26, 2017 Author Share Posted March 26, 2017 Well, this morning I noticed one of the pumps not running again only this time the power module was still lit so it looks like I'll be replacing the pumps. Quote Link to comment Share on other sites More sharing options...

danlu_gt Posted March 31, 2017 Share Posted March 31, 2017 These power converters are just converting AC to 24v DC. If you have a multimeter, check if the output is still 24V DC. It's pretty rare that the power converter would go bad unless they are underrated for the device they are powering. For example if the max output is 3A at 24V (72W) and the pump draws 90W, then over time the power converter will get burn out. The controller and pump are a different story.

Tried the new pumps on the old converters and low and behold they work. Pumps all along. Quote Link to comment Share on other sites More sharing options...
