Reef Angel Forum

im ordering a reef angel controller shortly and have a few very basic questions
does the pwm cable connect to the blue and white dimmer wires?
if the dimmers are set at 0% are the drivers off even though mains power is stll on?
is there a basic dawn/dusk on/off program in RAgen?
and finally will the digital to analogue conversion cable allow me to control "D" suffix drivers
thanks

Yes, it connects to the blue & white dimmer wires. Lots of people are using these drivers (myself included).
The way to do dusk/dawn on/off is via a function called PWMSlope (included in the libraries). The current version of RAGen does not add this functionality in however the upcoming release will give you the ability to add it in.
Yes, the digital to analog conversion allows you to control the D suffix drivers. I personally have a D driver and am using that exact setup and it works fine for me.

thanks for that Curt,are you able to post up a code i can copy and paste,lights ramping up at 8.30 am and down at 8.30 pm using the pwm outlets only
thanks

thanks,just a further question the "15" and "100" in the code are they the percentage of pwm ? if so i can change the 15 to 20 or 25 so the lights start brighter?

yeap

fantastic!

Hey guys I'm thinking about swapping my meanwells for the D version. Does going from the P to D really make a difference (5% from 15% at the lowest)? Where can I get that conversion cable? I saw some DIY sites but I'd rather buy it at this point. Thanks.

^^^^^^^^^^^^^^ X 2. I am also interested in this info!!

The PWM-to-Analog lead pack is available on the store:

That is the cable that I use to connect my D drivers to my RA.

a question on the code Roberto posted, on the 15,100,15, part what is stopping this from ramping up and down in a millisecond? what part of the code would give for example a 10minute pause at each figure or a half hour dawn and dusk

I can see the two types of Head Unit and the Dimming Port Lead Wire, on the store page, but nothing saying PWM-to-Analog lead pack. What should I order to be able to use the Meanwell digital drivers?

Thanks

I changed the design of the relay boxes.
They now come with either no converter or built-in analog converters and you need to choose what type of output signal you would like to have.
There is no PWM-to-Analog anymore. The converter components are now inside the box.
If you want to drive "D" version, pick the analog dimming. For "P" version, pick the PWM dimming.
This change made several improvements and the analog signal now is much stronger and can dim any fixtures with analog signal now.

The function works by minutes and not milliseconds.
I'm not so sure what you meant with pause.

That's ok if you are buying a new RA.

I am about to order my DIY LED parts and would go with the MeanWell digital as they appear to ramp down the lowest.

I already have the original build RA, but I could build an external A to D converter for each channel. Any suggestions on the type of chip that would work best. Is it 10 bit, serial?

Oh, they already output PWM digital signal. No need to do anything
Choose Menwell "P" version.

with this code how long will the lights stay at 15%?

I think the code I posted earlier was wrong.
I corrected it, but here is the correct version: This will start at 15% at 8:30am, go up to 100% within 1 hour. It will stay at 100% until 7:30pm. It will go down to 15% within 1 hour and drop to 0% until the next day at 8:30am when it starts again.

thats great Roberto when my RA arrives ill paste it in,its a nice basic code that others can use or modify,us noobs arnt into clouds and thunderstorms yet

Code: Select all

ReefAngel.PWM.SetActinic(PWMSLope(8,30,20,30,15,100,60,0));
ReefAngel.PWM.SetDaylight(PWMSLope(8,30,20,30,15,100,60,0));

This will start at 15% at 8:30am, go up to 100% within 1 hour. It will stay at 100% until 7:30pm. It will go down to 15% within 1 hour and drop to 0% until the next day at 8:30am when it starts again.

I am assuming the "60" in the code above is referring to the amount of time in minutes it will take to reach the 100%? If I wanted the drivers to ramp over a 3hr period, then would I just need to change this to 180? And how does it know to start at 830am?

Sorry for the newb questions

yes, 60 minutes.

just a newbie question is meanwell LPF-60D-48 & meanwell LPF-90D-48 are compatible with pwm model or analog model?

Seems like all of them, which is pretty nice
This is from datasheet:

Built-in 3 in 1 dimming function, output constant current level can be adjusted through output cable by 1 ~ 10Vdc, 10V PWM signal or resistance
between DIM+ and DIM-.

OK. Will Reef Angel PWN model will work with these drivers?

Yes, the PWM version will work
