Using RGBW extension to control 4 canals WW spots

[Gast]

Hello, i need to control 4 differents canal with 6 mini spotlights 3v 2w 700ma per canal. So i think i need to put a dimmer bettween the extension and the lights.
Do you already make this kind of install ? if yes which kind of driver did you used ? thanks

What exactly does this mean:
6 3v 2w 700ma

If you have constant current (CC) spots, the Loxone RGBW Dimmer will not work.

here the spotlight datasheet, didn't choose the drivers for the moment so i can choose CC or voltage drivers. but i need an advice to choose them ;-)

[Gast]

Nobody can help me ?

This is a CC spot, therefore you require a 700mA CC driver. You cannot dim this with Loxones RGBW Dimmer.
You may find a CC dimmer for the DMX bus, or a CC driver that is dimmable via 0-10V. Or, if not bought yet, select another spot with constant voltage.

Hi Christian!

Can the RGBW Compact Dimmer Tree be used with the following LED stripes?:

Any information would be greatly appreciated!

Please read the specs.
The stripe is 24V CV, that's OK. But the dimmer only supports 2.1A per channel, the stripe has 22W/m, meaning only 2 meter per dimmer channel.

Danke, Christian!

ok thanks for your answer Chirstian ;-) it's too bad because the RGBW dimmer was the fair price solution to control 4 diferents channels :-(

hello Chistian,

this driver accept dimming with PWM so do you think we could control it with RGBW dimmer ?

the meanwell drivers need a +v, 0v and pwm signal, you cant use pwm signal on the +v supply unlike a normal CV led strip
the pwm signal could come from the loxone dimmer in theory, but it needs 5v pwm signal and i dont think the loxone pwm dimmer will work at 5v supply
