I have a question about "clean" power for automated equipment. I have recently purchased a bunch of new equipment and I will soon be busy running dmx stuff to our catwalks. I have some color scrollers, a couple I-cues, some gobo rotators, and 2 VL1000 TSDs that are due in this week. When I was researching what to buy I understood that the VL1000s and my Apollo smart power supplies would need "clean" power. I was led to believe that Non-Dim circuits would not do the job. I'm not sure why. I have been doing some reading in preparation for putting all this stuff in and I have been reading Practical DMX by Nick Mobsby. In it he refers to having to use "direct or non-dim power." for fixtures and accessories. What can people tell me about when I can/should use Non-dim circuits and when I need to use a power source that is separate from the dimmer rack?
