Using a PACLED to control cathode tubes?

Pages: (1/3) > >>

TheShaner:

Is this possible?  I was thinking about getting a second pacled64 to play around with.  It would be really cool to dim and control the on off states of some of my other 12v lights, just not sure if its even doable.  Anyone know?

PL1:

Can you be more specific on the "other 12v lights" part?

LEDs? 161 bulbs? LV track lighting? Quantities?

TheShaner:

The main thing is the cathode tubes.  Any other lights will be LED's.

A PacLED or LEDWiz (or just about any of the LED controllers) can control just about anything you would want to control with them.

The key is to use the PacLED to control a Relay, and have the relay control power to your device.

If it's highspeed switching you need, you might use a triac or a SSR (Solid state relay). I used that technique to control several EL Wire segments as if they were LED's (complete with dimming ability).

I'm guessing a cold cathode is either On or off, and won't do highspeed switching (which is how LED's can dim, they're actually just turned on and off very quickly).

Do a search around here or google for 5vdc relay control. There's lots of example circuits floating around.

Good info doc, thanks for the nugget
