Tam Valley MFJ003U DCC Mono Frog Juicer (polarity reverser for frogs) (Scale=ALL) TAM-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.

Peco Electrofrog Update- All Frog Juicers work with Peco electrofrog turnouts without any modification to the Peco turnout. The same applies to other power-routing turnouts (e.g. older Shinoharas). You still need to insulate the Peco electrofrog turnouts as in the instructions that come with the turnout. For a normal turnout, that mans using insulated rail joiners on the 2 rails leaving the frog.

Peco Insulfrogs do not need a frog juicer as the frog is plastic and cannot be powered.
