View Full Version : LEDTriks output?
05-15-2008, 12:05 PM
I was just curious of the voltage output by the LEDTriks controller. I just don't want to fry 768 LEDs. I tried looking around, but can't seem to find it anywhere.
to the controller 1. Option 1. A filtered and regulated 5 Volt DC power supply capable of providing at least 3
amps at 5 Volts DC.
2. Option 2. Use the power supply located in the Vixen controller PC.
Either option is suitable, I prefer Option 1 – the separate power supply. Others will tell you that they
power their controllers using power from their PC. The one point I will make is that whatever option
you choose it must be a filtered and regulated supply.
From the controller to the panel I cant remember but its close to 2.2 v
If your testing the leds use a 3v watch/Pc mother board battery
The controller wile running used to put out 80ma at 1/16 duty cycle

I was curious of the voltage from controller to panel, because my LEDs have a 2.2v max

MY understanding of how the Ledtriks works, from way back last year, is that it puts out a slightly higher voltage and current than the listed max of the leds but it was not of concern because it cycles the leds so fast that it does not effect them.
Take that with a grain of salt because it is only what I think I remember. DO some more research before putting confidence in the above.

The output of the LEDtriks is current-limited by the value of R1/R2/R3 to around 18 mA, which is a safe value for almost any LED. This is based on using MBI5027 chips and 1K resistors for R1, R2 and R3. The output voltage of the MBI parts (and hence the LEDtriks) is limited to a safe value as a result of the current limiting.

Thanks for the help, sounds like my LEDs should work fine.
