    Default Delay Powering Up A Power Supply

    I have some dripping icicle tubes that have a 120vac input to 5vdc output power supply. I will be powering them on and off with a regular ac lor controller. When I plug the power supply in to ac the lights have a short delay before coming on. If I plug in the power supply ac with the dc side unplugged and the then plug the dc in to the power supply I get an instant lights on, which is what i'm looking for. Is there anyway to work around this delay? I know I can set it in my sequencer to come on early but I've noticed the other power supplies all have different delay times and I plan on running them on one channel.

    power them off you 684 board and do away with the org.power supplies or use them to power the 684 hopeful they are all 5 volt

    I don't think the icicles are intelligent, so trying to use an E6804 probably won't work.

    Best approach would be to switch the DC, but that involves getting an LOR DC controller. Another option would be some type of relay that was turned on/off by an AC LOR channel. Most important thing is to be able to handle the current of the switch on/off with the right size relay. A DC controller is the easiest.

    Or use your AC controller to activate a relay that connects already powered supply with the string.

    EDIT: oops, simul. post! Great minds, eh?

    Good old Radio Shack should have a relay.

    My only suggestion is to make sure that you set up the LOR Channel so it cannot accidentally be dimmed. I ruined some nice parts my first year because I didn't know that LOR had that config .. but they do ..

    Yeah Denny I learned the hard way back in 2011 with a spiral tree. Funny thing is, it made it to the last night of the show and the other one is still working. LOL

    Mark and Denny are correct on this. I have had to do this a lot, but I was firing up DC motors. The relay will give you that instant on. Be sure you use a LOD (my way) . That is when you use a C7 or C9 just before the relay on the AC side.
