  • Netzteil Dimmen 0-10V

    Zitat

    Das Geschäft wo ich das LED - Band und das Netztil gekauft hatte hat mir empfohlen das Netzteil und nicht den Streifen direkt zu dimmen.

    Hab mich jetzt doch dafür entschlossen das LED Band direkt zu dimmen mittels Shelly RGBW. Funktioniert super

    Dumb people give dumb advice, that is nothing new in the world. Besides, in the future, ELG is cheaper and basically the same thing. but atleast you got me interested, i am currently figuring out what has changed in the world to cobnvert 0-10v sourcing into 0-10v sinking for the meanwell drivers.


    PS if someone needs to use stuff like that in the future.

    The previously recomended PWM to 0-10v converter is really good for driving fancoils, HVAC units, motor controllers and so on, so basically one shelly RGBW if configured as output only device via Tasmota provides the control of 4 diffrent devices, which is really nice. Zero of the converters have failed me since 2012 :)

    There are possible ways to use Shelly Dimmer v2 with Triac constant voltage led power supplys, even vtac is a good option, 75w is the max rating to use without a issue.

    With constant current and shelly dimmer v2, the osram OTE series has proven to work nicely, i am currently testing with almost 160w of consumption on them,

    For the Shelly RGBW (whatever the v1 v2 or it is named) always use a 24v led strip, more power, better performance do to loss in wiring mm2 and so on.

    My testbench shows me that the shelly RGBW + 10 RGBW AMP-s is nicely driving over 1200w of LED strips :)

    Meanwells HLG provides his power by itself for the 0-10v controlling

    The 0-10v is intended to be used with a variable resitor, or else it will not work. if you provide the voltage to the 0-10v leads nothing will happen. It is current Sinking

    Besides that HLG dims from 10-100%, if you want to turn it of with dimming to 0% then you need THE ELG series

    Meanwells own statement to the misleading infortmation

    if you want to try it still out i have been using these for motor controllers.

    Remembered it, you need ta optoisolator with a input of 0-10v and a resistance from 0-10kohm. And this will work in reverse 10v will provide the lowest resistance. has been years since i did something like that
