The official WP40 running on controller thread.

Yes, I'll definitely post if I find the right socket. I'd feel kind of bad asking them for the part number as he's just trying to make a product. But, I think the RA is going to be around a long time and take significant market because of how open source they are and flexible.
I'm looking at those pin to edge dimmensions, and actually have a RA wp40 cable here to compare and I've got to say, I'm going to be really suprised if I got it wrong. The white cords are def. wrong. By looks this is the exact same one RA uses. For the DC barrel jack, can anyone confirm if its a 5.5mm x 2.1mm DC jack coming from the wp40's power adapter?
FYI, if you're making one of this for an APEX, I don't think you'll need the Low Pass Filter part of the RA design. Just a simple 2 resistor voltage divider since the APEX is already sending an analog signal. The filter (capacitor) is for cleaning up the PWM signal from PWM controllers (Arduino/RA).
 
im planning to use arduino as controller.
q1: will I need PWM signal or do I need to convert PWM to 0-5v analog signal?
q2: will I still need to use the jebao controller and connect it in between the stream and my arduino?

Maybe someone did this already for arduino an could post me some schematics/image?
I dont have my pump yet but already planning my PCB board.

Help would be much appreciated. I have already a controller for my TUnze 6105 but it seems to be different since Tunze needs 3-8v analog signal so I convert my PWM signal.

  1. Yes , you will need to convert to 0-5V analog.
  2. No, if you are using an Arduino, you do not need the factory controller

To make it easy, you may want to look at the ReefAngel cable available from their site as it will do the conversion for you from a PWM port. While you are there, check out the flow patterns their community has made for the WP40 on the RA (Arduino).

thx dennis.
unfortunately there is not much information about the cable and it seems like I only can purchase it with the pump.
Will check out their community - also It wont be hard to change PWM to analog anyways.
Thx
 
once again:
On Reefangel site is written, that Jebao Pumps can be controlled either via PWM or via Analog signal. So is there really need to convert?

anyways - cable from jebao seems nice but not for 25 bucks ;)

Yes, you need to convert to 0-5V analog. The pump is compatible with PWM and analog versions of RA controller but only using the RA-Jebao cable, this cable can be used for both versions. It has a voltage divider and a low pass filter so it can manage PWM and analog signals.

The values you need to make the harness, are the used in the RA cable:

Roberto RA:
The values used on the jebao controller was 1k and 2.2uF
I felt this wasn't good enough values. I was getting a lot of ripple when I scoped.
So, my custom harness has 10k and 10uF. I also used another 10k as voltage divider.
So, the 0-10V would be cut down in half and give a 0-5V to the pump.
This way, we can use 0 to 100% on the dimming channels.
Well, technically the pump has a cut off. I didn't measure it, but it is about 15% to 20%, so the usable range is 15 to 100%.
I'll look for a source of those 3pin connectors and we should have the hardness at the webstore soon

Hi,
understood.
So I will go with these schematics:
http://www.cctools.eu/ext_index.php/artikel/1420

Its a PWM to analog converter which I already use for my TUnze.
As Output you get 0-5v or 0-10 (for Tunzes you may of course only use 80% to get 8v as max). Its in GErman but Schematics should be readable, just in case anyone else is looking for such.

So the cable is a non standard? Of course I could cut the original cable from the controller and use is but would be better to get a new one.
Let me know if there is one available.

Also: Can I still run the stream with 12v Power? I think somewhere I read that the pump may not run lower than 12v. It wouldt make sence though since I could never run it lower than 50% would it?
I just know that Tunzes should not run lower than 3v (controller signal).

A little off topic: Why is the price for the 25er version almost the same as for the 40er? (Fishstreet) Any one an idea? I would prefer the WP25 cause it is so much smaller but still gives about 60-70% of the stream the WP40 does.

When the WP40 became so popular Jebao knew they have stumbled upon a gold mine. The WP25 was highly speculated to be just as powerful but smaller which created a huge demand for it before it was even launched. The price of the WP25 to be almost the same as WP40 is simply reflecting the market demand.

MEASURE your APEX output though, just found out mine is putting out 15.84 volts at max power!! not good.

Just wanted to set the record straight, the Apex was and is working correctly. My meter was reading 5v high! Thank you Neptune for looking at it and helping me figure stuff out..

Hey, i got the connectors, its the correct waterproof LED connector for Jebaos.. You can get them at Aliexpress http://www.aliexpress.com/item-img/...Pin-Waterproof-Connector-Cable/630198351.html

Doh! I got impatient and hacked the connectors off the factory controller. As it turned out, the power jack to screw terminal adapters I had ordered ended up being the wrong size (2.1mm, guess WP40 uses 2.5mm), so I had to salvage the factory plugs as well. My temporary wire harness is a mess of maretts and quick connectors. Lets just hope it is a temporary harness. :)

Thanks for posting the correct one though!

I tried the voltage divider using two 1 Kohm 1 watt resistors to control a WP40 with my APEX as indicated by ItzGenX.

100% continuous reads 4,85V, that's ok,

fast pulsing (0,8 seconds) from 0%-50% reads 2,6V, that's what was expected, but fast pulsing from 0% to 100% gives 7,7V.

Is this surge normal, or could this damage the pump?

Thanks,

These WP40's hooked to your own controller, running your own patterns, are awesome!

For the last couple of weeks I was using a Reefcrest type of pattern, or what I thought Reefcrest amounted to. It was a variable output pattern with a pump on each end set to x and max - x respectfully. Not sure how close to Reefcrest that actually is, but last night I added a wave component. Each pump toggles on and off alternating still using the variable sliding output split between the 2 pumps. I also increased the max limit since they are not constantly on any more so less chance of being too strong.

My Rics immediately opened larger, so they seem to approve.

I think this is for the power it can control, not for the signal, that means you can control motors that run from 6-90V, that only depends on the power input.
If you look closely in the picture where the potentiometer connects (White 3 pin connector) you can see clearly the 0-5V signal.

I know I have to cap it at min 12V.

This is the same one for only $13,46 and free shipping:

Will this controller work to replace the expensive AD110-A10 PWM LED dimmer for the dimmer mod?

I think you have an APEX? Why not just buy (or build) the RA cable and call it a day? Putting another PWM device into the loop when you can generate a 0-5V directly from your APEX seems to be overkill.

Unless you are trying to keep the factory controller instead of using your own controller?
