It seems that 0-10v dimming is making a comeback (or actually never left) in the architectural market, and it has me thinking about a project.
We are currently redoing our lobby areas and part of the longterm plan is adding lighting in areas where it wasn't originally. We have gotten around this in the past by using tracklights aimed all around, but that looks awful - and since we have moved to LED in the lobby, the dimming is marginal at best.
I happen to also have a pair of Off/Take Control wallplates by EDI which are basically new old-stock. I have been told by a former EDI tech that they are 0-10v. I see a lot of LED drivers out there that can dim using a 0-10v signal, and that LEDs in general can achieve better dimming this way. I was also told by this EDI tech that the op-amp in the wall plates won't pass much current, so I'd probably need to add buffers after the controls in the signal chain.
This is entirely a pet project, but also an experiment on my part while also hoping I can give these like-new wallplate controls a new life. Does anyone around here have any experience with 0-10v control of LEDs? I know we have a bunch of analog gurus around here and I would love to get some insight.
The wallplates appear to receive +15vdc for their own power, but I can confirm that with Alan Child. I just don't want to bug him too much since my LED idea is a bit esoteric and likely not in his wheelhouse.
Of course, all permanent 120v electrical work will be supervised and inspected by a commercial electrician.
