Can you build a dimmer in every driver?

[petrovich]

Hello folks,
i was just wondering what it takes to build in a dimmer in a LED driver. Im looking for a 250-300watt LED driver to drive 4 small 24VDC Boards. Each has its own 60 watt driver that has adjustable voltage 18-24v, so i guess its constant voltage board/driver. I want to drive them all with 1 single large driver, but these most times come without dimming. Saw some good offers, but always without dimming. Can i just buy one of these small aftermarket dimmers for a few bucks and hook that between the output and the board? Its just a simple potentiometer isnt it?

It looks like a potentiometer on my electric sky.
I have had dimmers that did not work with led high hats
Those dimmers are on the line side of the fixture

If it's a DC board, I believe they can all be dimmed.

I think so too.

DC voltage can be reduced by adding resistance so a POT will and should work

I would assume you need one that could work in the combined load range so to speak and feel if it heats up.
helps to have a ammeter you plug into to see wattage used

Yes one would need to be within parameters of the voltage applied
V=IR Ohms Law

Just go to any Radio Shack and show them the numbers you are working with

While there let me know if they still sell any Heath Kits
Im still trying to find the 20 inch TV in the wall one

I heard he like as a child to stick his finger in things that were quit shocking
