Tam Valley Depot DFJ003U DCC Dual Frog Juicer and Auto-Reverser

Duak Frog Juicer

Automated DCC Polarity Control for 2 frogs in turnouts and crossings. Also automatic DCC polarity reverser for wyes, turntables and reverse loops

For all DCC systems including NCE PowerCab.  This board can be configured to use as an automatic polarity reverser for two frogs, a reversing loop, a turntable, a wye, or a crossing.  It uses the same basic design as the hex frog juicer but has 33 Amp transistors so it can be used with multi-unit lashups and 10 Amp boosters.  Setup is simple, connect the input to the DCC track bus, and connect the output wires either to two frogs or two rails.  A jumper controls whether the two outputs act as a pair (i.e. an auto-reverser) or independently (i.e. a pair of frog juicers).  Another pair of jumpers controls the current set point for switching, either 2 Amps or 4 Amps.  When used for frogs or crossings generally 2 Amps work best and for an auto-reversing application, 4 Amps generally works best.
