The Answer to Model Railroad Enthusiasts Desiring Realistic Locomotion!!!

The PowerScaler works like an electronic transmission by adding 8 full scale throttle speed ranges to your power pack. It's like having eight individual power packs each with a different full scale range.

A typical power pack has a single throttle range. You must use this single range for every locomotive you have regardless of it's size. This means that for small switch engines you are forced to use only the lower range of the throttle while for larger locomotives you may be able to use more of the throttles range.
With the PowerScaler you can now DOWN SHIFT or UP SHIFT the entire range of your power pack's throttle. If you are operating a switcher, you just DOWN SHIFT and now use the full throttle arc for smooth control of the switcher's speed. For road diesels you just UP SHIFT for realistic mainline operation.
Regardless of which locomotive you are using, the PowerScaler lets you choose the most realistic full range throttle arc and still maintain a reasonable, realistic speed. No longer will you be limited to using only the low end of your power pack's throttle range!
The PowerScaler is fully compatible with all power packs, both DC and Pulse, and will not interfere with features such as DIRECTION, BRAKING and MOMENTUM.
