If doing it again, I'd either do the Loxone battery PSU for one stop simplicity, or roll my own using AGM batteries and 24V regulator, and perhaps drive LEDs direct from the batteries (esp any constant current fixtures) to avoid the overhead of regulating them. Just will take up a couple rows as you say But it also has negligible power on time and very quiet, and fits a future automation cabinet well. The meanwell you link had very low standby current so probably no need to power them off even if unloaded (all lights out). Yes I currently have one of those, and also a noisy as heck cheapo 1kW supply for LEDs that I only fire up when actually needed. I guess something like this would do (I believe one in his cabinet).Īt £44 each I'd need 8 so cheaper than the Loxone Power Supply and Backup but I have a feeling that 8 of these will take up a lot more space in the cabinet! And also not have the reporting capabilities that the Loxone one does, e.g.
I do have a Whitewing mains dimmer 16-channel ( )
#Loxone rgbw dimmer driver
īut I presume I will still need a control mechanism for the remote drivers, like a DMX driver ( ) but if I didn't want to use DMX how else would I control the lights? would that need to be a Loxone Dimmer extension ( )?
#Loxone rgbw dimmer drivers
I could, in theory, move some of the LED strips to have remote drivers so they're powered by 230V cable like this that F sent me. Have I got this completely wrong or does this seem about right for a system of this size? IF I've got an understanding of it all I calculate that I will need a total of around 1.3kW PSU!! here's my spreadsheet table showing the calculations:Īnything that says 'Powered by Miniserver' isn't included in the totals at the bottom for the Total Watts and Amps. As if I can get a handle on that I can decide if I want remote or central (or a combination of both) drivers. I think I'm improving my knowledge around the whole 24V led strips subject and my attention has moved to the power supplies required for my setup. (This is all subject to spec of the tape you source though. To avoid the 10m of 2.5mm2 you either need a 24v PSU closer to the RGBW Dimmer, lower power LED strips, or you could look at using a 230v RGBW driver (would need to be DALI or DMX) in the bedroom rather than the Loxone Tree one. (this is independant of if you use 1x10m tape or 2x5m tapes in parrlelel as total watts/amps is the same) 2-core 2.5mm2 from 24v PSU in pant room to RGBW Dimmer (assuming 190W worth of tape). 2 lengths of 5-core flex from a single RGBW Dimmer to each length of tape (this can probably be 0.75/1mm because i) it's close ii) each length is only half total watts). Almost certainly two lengths of LED tape wired in parallel (not one length) I presume that the Cat6A cable from the cabinet to the dimmer will take the power the dimmer requires? just like any other Tree device like a Touch or presence sensor? a single Cat6A from Loxone cabinet to the compact dimmer in the loft void above the room and a suitably sized cable from the compact dimmer to the strip. so, in my mind, the second option using a single 10m run of RGBW strip sounds a lot simpler. so would I need 2 x compact RGBW dimmers per room then? 5m of LED into each? seems excessive!Īny voltage drop calculations I will leave to my electrician so will run any potential solution by him to check the calculations! one wall is 4m and the other 6m in length. The strips will be run around 2 walls in each bedroom in an 'L' shape. These save you running 5 core, but you still need to be careful with voltage drop as they are 24v in, not 230v. You could use a single chunky feed and then split off in to 4 somewhere in the bedroom, or you could run 4 thinner cables all back to the same driver (assuming you are withing wattage of driver). So if you are going around all the way around a 3mx4m room (depending on the LED product you use and recommended maximum length) you'll probably want to 2-4 feeds.
Local drivers saves calculating voltage drop of course.Īlso, if you have an LED >5m and/or going around multiple walls, you really need to run the multiple strips in parallel rather than in series. This works with 5m of 12W/m LED and a 10m feed, but if any of these three parameters are much higher, you really need more than 1mm2 or move the driver closer.
