Re: Divide or not
Inrush current has no numerical value because there are a lot of variables.. But in all cases, it will exceed the current draw of just about any booster made. The question is how long does it draw this current. If it exceeds the rating of the booster longer than it shutdown timer will allow, the booster will shutdown.
This problem is no new. This same EXACT problem happened when sound decoders made their appearance. The more sound decoder were added to the layout, the worse the inrush current go until the booster could not support it and shutdown.
Today most DCC circuit breakers are design to deal with the high inrush current problem when there is a short circuit. Recovery problem solved.
To your question, should you drive the DC240 harder. I understand that changing shutdown increased the inrush capability, but Digitrax has no specification. This is the same question as “ How many more sound locomotive can I add to my layout". Every time you add another signal controller, the inrush will go up some amount as you need to charge the capacitors on each additional signal board. As you keep adding more, at some point your problem that you just solved will reappear. So it is not how much steady state current draw you can you push, it how much inrush current can the booster support. There is no valid answer because there is no specification nor DCC standard for inrush in which one can use figure the answer out.
