The N Scale railroad that I'm planning will have 24 Kato turnouts, each powered by a DPDT switch wired to a 1000 mfd capacitor and two 5mm LEDs, only one of which will be lit at any one time. 2.2K Ohm resistors are wired with the LEDs. I'm using a common circuit design. Will a simple 12 VDC 500mA "Wall Wart" Transformer be able to support this assignment? I'm thinking that it might be weak, but then again, it's output is 18 VDC unloaded. 24 LEDs * 20 mA Ea = 480 Total 24 1000 mfd Capacitors * ??? = ??? Total (Max draw at startup as the caps charge) Any advice is welcome. Thank you.
