Jebao WP25 Information

This thing rocks the tank. I attached a different power supply that I had. It is 15-24V and I set it to 15V, plus I was able to set the dimmer around 50-60%. All at H3 mode.
I have a question about "night mode". Does it mean the at night mode and "Else", the "else" random flow cycle will still be in effect but it will be reduced to half speed? Or does the "night mode" just switch to fixed 50%, period?

It was my understanding that the jebao was controlled by a 5v pwm signal just like a computer fan.

I don't know anything about the reef angel but does it output 5v pwm or 10v pwm? if 10volt it would need the resistor network to reduce to 5 volt.

you could just as easily us an arduino to control the pump I should think. writing your own wave sketch.......

has anyone confirmed what happens if there is no pwm signal to the pump but it is supplied with 24v power? does it run full blast or not at all? if connected to an arduino does it behave like a computer fan not allowing it to go below 30% power even at 0% duty cycle?

Jebao takes 5v PWM. RA does supply 10V, but the Jebao cable has a voltage divider to drop that down to 5V. The cable also has a low-pass filter that "converts the signal from digital to analog". You could just as easily run the pump at 50% max to maintain a signal lower than 5V, but that comes with risks of exceeding that and burning up your PWM pin on the Jebao.

With no signal on PWM, the pump turns off. No signal, no speed.

You can use an arduino if you are willing to write the code yourself.
 
It's been awhile since I have been in this thread, but I wanted to update my experience with my WP25s.

-I have also experienced the loss in flow when the pumps become dirty. I actually had a bio bloom at one point and couldn't figure it out, until I noticed my pumps were not putting out much flow. Cleaned them, flow and surface agitation back to normal, tank clear by next day.

-While using the WP25s with my ReefAngel I was able to run custom flow patterns on them with the ability to run them in anti-sync. However, in modes like 'else' My pumps would stop within an hour or so or overnight. I tried several different ways, but they always ended up stopping. If I ran them in pulse, 2 seconds high, 2 seconds low, they didn't have this issue. Now, I believe this has more to do with the code I was running than the pumps as they work perfectly with the stock controller in every mode. I plan to test this more in the future when I get some time, but thought it might be useful to someone prior to that.
 
I have been using a WP25 on my 65 since MacBoat's group buy. It has been in W1 mode running flawlessly for months. The WP25 runs during the day to provide a rocking motion, I have a 1600 gph single speed wavemaker that runs 24/7 to provide current. Both of them need a gentle cleaning with a bottle brush every now and again to keep up the flow, but I almost never have to pull them out to clean them.
 
I have had mine for a few months now. I run mine with the sensor. Durning the day it's on w1 and then at night it's in else I believe. These are wonderful!
 
My sensor never worked on these---anyone have any suggestions ? I would like it to so the flow would slow down at night.

I am designing a battery backup for my WP25s. The thing that is stumping me is how to get the dimming signal wire to have say ~2V constant when it trips over to backup? I removed the existing controllers and use the apex to modulate the pump.

If I lose power the pump would be able to receive 12V from the batter to power it (1/2 normal voltage), but it would not have any dimming signal, rendering it useless. Ideas?

Edit: 3V wallwart plugged into UPS or something? I'm not sure where to start.

put a voltage regulator on the control line with a relay to switch over to it when the power switches over to the battery.

rrasco,

Are you sure about that? every post I keep finding says it needs 0-5 volt analogue signal not PWM. But, I've not seen anyone who's hooked the controller up to a scope to really see what it's doing. PWM seems more likely but anything is possible. So to use arduino I'd need to convert that to an analogue signal.

If it's really voltage based you could just put a potentiometer in line with the control wire and dial it down a bit, but that would be too easy, wouldn't it?
 
Why do people slow the flow at night?

In real ocean reefs, currents aren't any calmer. Its sometimes even more chaotic and stronger.

Ack, I didn't mean that. It's a 5v analog signal. The RA and/or Arduino PWM signal can be converted with a LPF.

The guys at ReefAngel have had the WP40 hooked up to a scope.

I've been looking all over for that post...........

Thanks rrasco!

Does anyone happen to know how much current it draws from the controll signal? Arduino outputs 40mA so wondering if the pump can run directly off the Arduino? I can't seem to find this anywhere either, and I've been looking for some time now, thanks, in advance.
 
Fish street has changed their logistic in shipping products to the US. I just ordered another WP25 from them last week. It was shipped out last Saturday and delivered by USPS to my house at 1.40p today... A total of 5 days. What is interesting is the mailing label was generated in US with a NJ return address. FS must have shipped them out of HK to a central location in US which then reshipped to the customers. 5 days international shipping is pretty impressive and better than many standard domestic shippings.
 
Alright, so for a DIY Battery solution you just need a Tunze safety connector and the biggest sealed lead acid battery you can find?
 
Basically, that is it.
I had a post in here or the WP-40 thread with about 4 different options to do this.
I don't remember where it is right now, but the methods exist.
 
Anyone have an issue with the pump locking up? Every morning I wake up and one of my pumps isnt spinning. All it takes in unplugging the power and plugging it back in and its back on.
Both of my pumps are running the same programming so I dont think it has anything to do with that. Fish street says theyre sending a new impeller, just curious if anyone else is having this happen?
