Open the regulator and the loco starts to move. Leave it open and it will accelerate, close it and the loco will coast. To stop, you have to use the brake. Done correctly, nice smooth stops and starts are possible. It's switchable for different motor types and again uses high frequency pulses, so the motors keep their cool.
Current limits are as for the hand-held version.
All Pentrollers need a source of low voltage AC, in theory 14 to 18 volts. Here's my solution. This is a simple task to do, but if you aren't sure about working with mains current, then it's best to seek qualified advice. Another thing to do is change the low voltage connector . Using a 12 volt AC feed, means that after taking into account losses inside the controller circuit, track voltage is a maximum of 9 to 10 volts which is about right, especially considering the low current output.
