splitting control channel on a storm x controller.

skanderson · 12/17/2018, 08:53 PM

as the title states I am wondering if it is possible to split the control signal off a storm x controller. my new supplemental led system will need to have somewhere around 40 different ldd drivers controlled. I only need around 6 different channels set to different types of leds. but will be controlling 10 ldds running vero 18 cobs for example which will each need a separate ldd to power them. I seem to rememeber reading somewhere a few years back that you could split the signal but just wondering if anyone has done it so I can order a bunch of storms if needed. thanks, steve

Ldd dim circuit requires little current (like micro amps). Storm X 5V out has little (but a lot more) current than LDD's require (40 milliamps (I think)..

Each channel, theoretically, can handle dozens of Ldd signal wires..
suggest limiting it to about 3 or 4 until someone actually ran more..

Point is I seriously doubt you need more than one Storm X.

16channel 12bit PWM (Storm X)

I'd be surprised if you couldn't "do" 50 LDD's off those 16..

hmm StormX only has 10mA..

Max PWM current per pin :
40mA (Storm),
10mA (Storm X)

OK what Meanwell says..

Quote:

1mA at PWM dimming OFF and 24VDC input

conservatively 16x 5 = 80 drivers..

thanks for quick reply. will work on splitting the channels and post on a build thread when all the leds are in and im ready to power one up.

A whole bunch more than what you need...
