Model Train Power Pack with Speedometer, Voltmeter, and Ammeter

Description

The Loco-Power SVA-20 is a DC power pack that features a digital speedometer, voltmeter and ammeter. The back emf of the trains motor is measured and used to calculate the speed. This allows the scale speed of the train to be displayed and updated continuously as it travels around your layout.
The output of the SVA-20 is pure DC which is generatated with a switch mode converter for efficiency and can provide up to 15 VDC at 1.5 amps.  If the current limit is exceeded an overload warning light will go on.
The speed calibration can be performed manually or the SpeedTrak II speedometer can be used for automatic speed calibration.
The calibration of up to 99 trains can be stored in memory.
