      power supply

      Hi all,

      I am pretty much brand new to G gauge trains and DC power.  For background I am building about an 80 foot L shaped loop with a passing siding or maybe two.

      Currently I have an Aristocraft U25B, a Delton 2-8-0, and a Bachmann Spectrum C-19.

      I want to use track power and am looking for larger power supply.

      Here is where I need help:  The manual for the Aristo U25B requires a "PWC", pulse width control, power supply.  This ART-5400 1.8 Amp power supply isn't going to run my other locomotives and power a couple of switch machines etc.  

      The manual for the Delton, and the Bachmann have virtually no information on power supply recommendations that I can find.

      Can someone explain what the problem is and tell me why I can't just use a 15 AMP MeanWell 24Volt power supply?

      Thank you in advance,

      George

      Hi George, welcome to LSC.  The Aristo U25B does not require PWC, regardless of what the manual says. PWC gives better lighting and smoke performance because those devices even out the pulses, but they will still work, just not at low throttle settings.  I think the Meanwell and an appropriate controller will serve you well.

       

      Do you realize you have purchased locomotives in three different scales?  Welcome to Large Scale Hell!!!! The U Boat is 1:29, the Delton C-16 is 1:24 and the Bachmann C-19 is 1:20.3.  The C-19 is the best loco Bachmann ever sold in large scale - runs like a dream.

      Jon,

      Thank you for that explanation.  I mostly model in S gauge and we have experienced the huge changes in smoke output when running Lionel American flyer locomotives using a Chopped Sine Wave transformer.  Glad to hear that is the only concern with the Aristo U25.

      As for scales yes I realize the differences, and it is a real PIA.  I want to build an early freight train with appropriate size cars for the C-19.  The Delton is a toy which I have only run about 15 minutes, that one may get sold.  As for the U25 I have some Bachmann cars that are ok size for it.

      Thank you,

      George
