The Mono Frog Juicer is for use with most DCC systems including Lenz, Roco, NCE (including the PowerCab), Digitrax, Zimo, MRC, CVP, SPROG 3 and more.  This 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 frog. The frog should be fully isolated. When a train crosses the turnout and the frog is the wrong polarity, the 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.

NOTE: Not for use with Analog DC or Bachmann EZ DCC, SPROG 2 systems as they do not have enough power to reach the 1.7 Amp switching threshold.

    Simple to hook up and worked perfectly. Used it to switch one frog of a diamond. Added a Second one for the other side and it worked flawlessly
