More gadgetry? 0-10V light control for the new office
If you've not watched the installation of the projector screen, the video is below. But sadly I discovered that the lights in the place are all on a single relay... no local dimming. Undeterred I snooped around, these are LED panels, you would think some sort of PWM or other dimming would be possible, right?
Turns out they implement a crusty old standard called 0-10V. The panels are from Earthronics. OK, so now I need a way to get 0-10V up there on the ceiling, with me on the floor. Interestingly, the standard calls for being either a source or a sink, its kinda fuzzy, you have to know. The power supply is an XZ-LK50B (here). But, the xz-power site is down. Hmm. I'll assume we are sourcing.
A little googling, and some credit card, and I am the proud owner of a Keilton PPA101S. Sweet. Got ladder, screwdriver, and a desire to muck w/ the lights, which may or may not dim once done.
