LDD Drivers, why and how?

You should look up my dimming acclimation code makes acclimation seamless

Your code works perfect. Am currently running it to re-acclimate my corals in my 29BC to LEDs.

New question.

How can I convert my 10V Analog relay box to 5V PWM?

You will need to open the relay box, short out some pins and remove some components.

Is it easier to convert an existing PWM box to 5v?

--Colin

[rimai]

Actually, my bad.
If you are using one of the newer relay boxes, you don't need to remove any components. You just need to short out some pins.
Either signal would still be just about the same work if not the same.

That's good news. I think I'll just do that until a RANet dimming expansion comes out.

Can you point me to some instructions?

Thanks,

Can you check which relay box revision you have?
It will be printed in the pcb.

[cosmith71]

Yep, will be a couple of days before I can dig into it. Stoopid job! Always getting in the way of my leisure time activities.

Will Cat5 network cable carry dimming signals?

--Colin

[rimai]

Yes, for the dimming signals, you are fine with CAT5

[cosmith71]

It's 8.1

[rimai]

You need to short out the legs of R20 and R22.
Make sure to move the jumpers too, so you get PWM signal. The marking in the board is wrong though.
It should read PWM/Analog instead of Analog/PWM

[cosmith71]

Got it. I'll probably be doing this project this weekend.

Thanks!

Update!

I've been running these for a few months now.

I have 8 LDD drivers running open-air on top of the canopy. They run hot, but much less than the rated max. I used a Genssi 48V DC 7.3A 350W Regulated Switching Power Supply from Amazon. I've had no problems, but the fan is kinda noisy when it switches on.

LED list is as follows (all Cree):

RB x32
Blue x8
UV x10
NW x10

No lenses. Lights 6-8" off the water. I have a Crocea clam on the bottom which is doing great, as well as a ton of LPS at all levels. I have a soccer ball sized green pavona mid level towards the back. Zoas, softies, etc. Everything is doing well. I'm going to load up the acclimation code and try some more SPS.

I used the Rapid LED driver boards. I don't recommend them. They use a spring-loaded connector which doesn't hold the wires very well. I'd much rather have the screw down kind.



Thanks for all the input! I'll try to get a FTS after the lights come on.

Full tank shot.

Looks great man!

I did this to quiet down my power supply

[cosmith71]

Lee: Thanks!

Pandimus: You replaced the built-in fan? There's a thought.

Yep, it plugged right in and considering its a bigger fan it spins slower and creates more air...just a bit more bulky
