Big Power...30VA gets you going � ammeter and voltmeter put you in control Runs HO, N, TT, Z and other DC Scales. Meters monitor your layout to optimize railroad performance. They can tell you what�s happening. For instance, if the meter indicates your loco is drawing too much, maybe you should lubricate the gears to overcome friction before it overheats. Or both ammeter and voltmeter flutter, a sure sign of intermittent contact...clean the track. High current and low voltage appear at the same time...maybe there�s a short somewhere. The 9500 puts you in control. Features Include: Momentum control with on�off switch Fixed AC terminals for accessories Fixed DC terminals for expansion Light emitting diodes indicate momentum, power output and overload conditions Advanced Proportional Tracking Control for maximum realism Spring-loaded brake switch Direction control switch 5-year limited warranty
