Hiya all! I am ONE step closer to achieving a "cheap" DIY wavemaker...

Yesterday, I went to my LFS to acquire some goodies for my new sea horse tank.... ie. water level alarm, digital thermometer, AND:

a Boyu intermittant switching timer:

NOW - this device cost me: R89!!!!!

My 2 x ReSun's are now being switched ON and OFF intermittantly.... BUT - this is a 220 volt device.... Meaning I am still using my standard ReSun wavemaker/timer and power-supply - So, I now have to figure out how to get my standard ReSun wavemaker/timer to ONLY stay at 15000 litres/hour!

Anyone know how to do that??

So - what ya all think?

those switches are damn nice.
also want to know how to keep it at 15000l/h:whistling:

nice toy jacques!What is the use of the wavemaker then.cant you just cut it off and just connect the pumps to the new toy???

NO, The resun WM is a 24v system I think, it would pop it in a second.


Also have 2 Resun WM, will pop the cover and check the electronics, should be able to do it;)

You 100% correct lIghty - the pumps are 24 volt.... I presume that the actual voltage drop down and recifiers sits in the power-supply, and NOT in the wavemaker/timer?

If this indeed the case, then it should be as easy as connecting the wiring that comes from the pump, to the wiring that goes to the power-supply (bypassing the wavemaker / controller).....

No, I've put the output on my ocsiliscope and it is a type of PWM, so don't think it would work....:whistling:

lIghty - I found the following as well:
(From: URL: Resun Waver 15000 [Archive] - Atlanta Reef Club Forums)
"An additional note: I hacked the controller off and wired the brick directly to the pump. Oddly the transformer kicks zero volts out. It must need a specific load before it will push full voltage out... probably a safety feature. The transformer still will power the controller and the pump when wired back up. Unfortunately I don't have a power supply that kicks out 24v at 1500ma that I can use to get this in my tank for long term testing. I plan on ordering one for $10 and see how long the pump will run full out. I did try it out at 12v with a PC power supply in a test and the pump fired right up but obviously at around half power."

Hi guys - I had another look at my ReSun Waver and power-supply over the weekend, and it now makes much more sense - AND NOT!

The standard power-supply that comes with the ReSun Waver is an AC-to-AC step-down transformer only. NO SMOOTHING of the power-signal, and not rectifying....
The pump itself is DC - so, the rectifying and smoothing of the signals happen in the actual timer box itself.

The timer box contains the rectifier as well as the smoothing capacitors.

So - I will HAVE to look at DIY'ing a power-supply for my 2 ReSun's (from 220Volt AC down to 24 volt DC) - I wonder if I use a 30volt DC, whether I will get MORE OOMPH out of my DC ReSun pumps?

Those dem power-supplies, and 2 boxes to put the power-heads/pumps in, is all I now still need to get my wave-maker up and running!
