Controllers

What is the difference between a feedback controller and a normal type?

A controller which incorporates feedback helps to maintain constant speed control when a train is ascending or descending a gradient, negotiating curves, and going through complex pointwork. The built-in feedback circuit senses when the loco's motor speed deviates from that set by the operator, and adjusts the controller's output to compensate.

Normal controllers have only a limited ability to compensate for changes in loco motor speed, hence trains can often run out of control on steep gradients, or slow down when going through a set of points.



Why should I use a hand-held controller?

These come into their own when the operator needs to move freely about the layout, and provided the lead is long enough, he can watch the operations he is controlling at close quarters, whilst maintaining full control.

 

Can I run Trax controllers on 12V dc?

The FC-1 and FC-10 require a 14 to 18V ac supply to ensure correct operation, so use a mains transformer rated at 1.5 amps or more for each controller in use.

If using a dual output transformer (i.e. 0-15V, 0-15V) you can use one winding for a controller, and the other to feed another controller or an accessory.
