Tam Valley Depot DCC autoreverser is fast, reliable, and easy to install

摘要

The Hex Frog Juicer from Tam Valley Depot is an automatic reversing circuit for turnout and crossing frogs on Digital Command Control layouts. Each unit can power and reverse polarity for up to six frogs, enough for as many turnouts or three crossings.rnThe Hex Frog Juicer senses a short circuit - any load exceeding 2 amps - when a metal wheel bridges the gap between the frog and an adjacent rail of opposite polarity. A microprocessor-controlled circuit switches the frog off and then back on with the polarity reversed. The short circuit is resolved within 50 microseconds, so neither the motion nor sound effects of a locomotive are interrupted.rnWiring the Hex Frog Juicer means connecting two wires from the track bus and one wire to each controlled frog. Screw terminals are provided on the circuit board. A simple instruction sheet includes a wiring diagram for crossing frogs. The circuit is powered by the DCC track bus, so it needs no additional power supply.
