DCC Mono Frog Juicer (polarity reverser for frogs) – #TVD-MFJ003U
Please note – Frog Juicers are DCC (Digital Command Control) devices ONLY. They will not work with DC or 3-rail. They will work with most all DCC systems, Lenz, Roco, NCE (including the PowerCab), Digitrax, Zymo, MRC, CVP. If you don’t see your DCC system here, don’t worry, there are just too many to list them all!
Alas, they will not work with the Bachmann EZ-DCC system or the SPROG II as they do not have enough power to reach the 1.7 Amp switching threshold. However, if you use one or our boosters then you can use frog juicers and other auto-reversers with these systems.
DCC Mono Frog Juicer (polarity reverser for frogs)
For all DCC systems including NCE PowerCab. 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.
