I was going to mention this in my other thread, but thought it warranted a separate one. In my 2011 display, I had a couple of DC channels that needed to be switched on and off with no dimming. I ended up using some spare channels on a DC24 and made sure I never dimmed them. They were driving some meteor tubes via step-down regulators and dimming them would have resulted in high current draw and possible damage. I can see that on/off would be good for some simple animated props with fans or motors, etc. Things that you want to control, but definitely not dim. So, is there a need for a DC controller with pure on/off switching? How many channels? Does it need multiple voltage banks to make connection to your oddball display items easier? Comments? Ideas?
