<p>[quote user="rrinker"]</p> <p> Always do the quarter test to make sure SOMETHING cuts off the power in the event of a short? Insufficient feeders or anything that allows less than 5 amps to flow would not trip the booster, so you could have 4.999999 amps at fuill track voltage flowing through a short - nearly 60 watts at 15V to the rails.</p> <p> However - the PSX breakers are rated to handle - hmm, the documentation doesn;t state a limit, though the max trip current is 19 amps and there is a note not to exceed 10.2 amps continuously unless you add heat sinks to the transistors - at any rate, if you can run it that high, then the insualtion on the transformer should not melt at those levels. And with only 5 amps available at the source, it's impossible to put 19 amps through the PSX. Accidently fed power int he wrong way? If anything, this would damage the transistors, not the current sense transformer. Transformers don't care which way the current flows - other parts might.</p> <p> All a mystery.</p> <p> --Randy</p> <p> </p> <div style="clear:both;"> </div> <p>[/quote]</p> <p>As stated in the initial post, the command station is tripping off the layout, which is the problem. </p>
