<p class="MsoPlainText">An interesting issue that just occurred to me. Sure, you can run an entire position of LED fixtures off of 2-3 20A circuits, but is it really wise to gang that many fixtures together? Say you need to cycle power during a rehearsal
or show, do you want the entire system to shut down, or just the troublesome fixtures? G-d forbid a rat chews the wrong wire in the wall -- how much of the position do you want to lose?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Consultants on the list? How many circuits do you spec for a position in an all-LED facility?<o:p></o:p></p>

<p class="MsoPlainText"><span style="color:black">From a manufacturer’s point of view, a common number that we recommend (of course depending on the power draw of the fixtures) is about 10 units at 120v.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">Little LED units may have 20 or more on a circuit without popping a breaker, and larger Production units may limit you to as few as 3 or 4.
<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">Most of our fixtures have power linking (a power passthrough on the unit), and the maximum number of those same fixtures that can be linked are in our specs.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">We include a hefty buffer, and have it certified as a part of our UL/ETLc/MET testing.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span style="color:black">Specifically to Steve’s point…<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">[WARNING, potential commercial post]<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">We do make a cool little product for Power and Data distribution called the Synapse 4.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">It has a single 20amp power input, and 4 individually controllable outputs (also a built-in 4 port opto splitter).<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">The outputs can be triggered via DMX, or internal clock, or DMX sensing (when the console is turned off, the unit waits a predetermined amount of time, and then cuts the power).<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">It’s basically a 4 heavy duty 4 channel relay pack on steroids.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span style="color:black">We made this because we found that some of our customers never turned their LED fixtures off.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">This basically negates all of the power savings, as a LED fixture which is powered on, but has the LEDs at 0% still uses anywhere from a couple of watts up to over 20 watts.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">The PSU, and all of the electronics are always running, if the thing is plugged in.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">Killing the power not only saves on the electric bill, but makes your units last a lot longer too.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black">If you’re going to spend more on the LED version of a fixture, you certainly don’t want to have to replace the PSU after 1000 “working hours” because the PSU and all of the other electronics ran 20,000 hrs in
that same period.<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoPlainText"><span style="color:black">Anyway, we make the Synapse-4, and it solves a bunch of problems… and it’s cool…and chicks dig it…just ask my wife.<o:p></o:p></span></p>
