Tam Valley Mono Frog Juicer (polarity reverser for frogs)

Tam Valley Depot DCC Mono Frog Juicer (polarity reverser for frogs):

For all DCC systems including NCE PowerCab.  The mono frog Juicer board is an automatic polarity reverser for a single frog.  Setup is simple, connect two wires to the DCC bus and one wire to a fully isolated frog. When a train crosses the turnout and the frog is the wrong polarity, the Mono Frog Juicer will reverse the polarity so quickly that the train and the rest of the DCC system will never notice.  Should not be used with boosters over 5 Amps.  See the Dual Frog Juicer for 10 Amp boosters.

MSRP is $14.99.
