The power supplies are switch mode supplies.
I did some tinkering last night and replaced the 470uF 63V decoupling capacitors with some 520uF 100V and it seems to have removed the pulsing noise.

Ahhh, switching supplies are nice, very light! I'm surprised you were getting pulsing from that - 470 to 520 uF shouldn't have made a huge difference. I guess if you're pushing the limits of the supply it will do that though.
Since you're pumping a lot current through your drivers, just to make sure you're not hurting anything, hold your hand on your gecko's after they've been running for a while. If they feel quite hot, you might was some fans (or a current limiter) in there. If they only feel warm you're fine.
Glad to hear it's working better, though! |
