this is what I use for powering my railpro system.  it is probably more power than you need for the AM and AR modules, but this is a solid unit.

Mean Well LRS-100-15 Switching Power Supply, Single Output, 15V, 7A

on amazon for about $25.

You can power the TC-1 with any power supply that provides a maximum voltage of 16 Volts DC.

Since you are not powering track with it, it does not need to be identical to your track power source.
You should be aiming for 14 volts DC.

Well, took the plunge.  Ordered 15 of the mp-8 switch motors.

 From what I have read, this is a motor that can operate, in this case, a switch. With the momentary push of a button, or in this case, the hand held railpro controller, the switch will be activated and a slow movement of the points will occur, as opposed to a snap.

I’ll keep you posted.

Kind regards,

That's a really good question. You've pretty much only got two choices, you can try the normal way by holding back the locomotive and using the auto set method, and if that doesn't work you'll have to set the full load current manually using your best judgement.

i run my layout a couple times a week, maybe one train is run and takes an hour. so that comes out to a little over a hundred times a year, with recharging after every run. I changed the batteries a year ago, and they last the whole session, with the battery gauge icon in the top corner showing about half. I've let it go after a run and not recharge, but run again and the battery icon will be down to 1/8 at the end, with full control even then.

Looks to me the HC is very efficient and the batteries should last at least a couple of years with light-moderate use.

what say you?
