The Dual Frog Juicer is more feature rich than the Mono Frog Juicer and can be configured for use as an automatic polarity reverser for two frogs, a reversing loop, a turntable, a wye, or crossing. It also can handle loads up to 10 amps.
The Dual Frog Juicer is for use with most DCC systems including Lenz, Roco, NCE (including the PowerCab), Digitrax, Zimo, MRC, CVP, SPROG 3 and more.
It can also be used as a circuit breaker to control a power district (with the bonus it will reverse polarity if needed). 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.
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.

Works well as advertised. Stopped BLI Locos from stalling across MicroEngineering N Scale track metal frogs. Will probably order more to cover all my ME turnouts
Terrific item and does what it says it will do.
I use this Dual Frog Juicer for polarity reversal for my three turntables. They work perfectly. My only comment is that for the novice, a bit more explanation of the wiring, specific to turntables, would be appreciated.
I've had DCC for over 20 years. Easiest reverser to install. Works great. No blinking lights no hesitation. No problem with mutable sound unit lash-ups.
Used this to control one leg of wye. Easy to understand directions and wiring. Put jumpers in correct postion and worked flawlessly. No blinking of headlight when crossing rev direction. Very sweet
This product was easy to install and worked perfectly the first time. One of the features I like are the rubber cushions on the bottom of the board so one can screw it to the underside of a layout without worrying about the connections on the bottom side of the board hitting anything.
These devices allow those of us who use "dead frog" turnouts to power them up...and keep our short wheel base locomotives from stopping and restarting while crossing the turnout frog.
They are easy to wire up and use...just hook a wire to each of the bus for the DCC circuit...and one to the frog...and you're done. The only thing to consider is that all connections to the power bus MUST BE THE SAME or you will create a dead short...and could damage the frog juicer. This item can also be used to reverse polarity in reversing sections...
Priced right...pretty much every railroader can afford these...especially when you consider the amount of work saved...and materials...like a micro slide switch...and all the wiring.
I have a NCE Power Cab. I used this as an auto reverser on my layout. It was easy to install and worked exceptionally well.
REVERSE TRACK CONTROLLER-
I am using the dual frog-juicers to control the reverse sections on my N scale layout. They install easily and work great. If using as a reverse section controller, remember to change the orientation of the jumpers on the circuit board.
There is nothing worse than hearing a sound-equipped loco sputter and re-start as it hits a dead frog. The frog-juicer eliminates this problem if you are using live frog turnouts. I am using N scale code 55 Atlas turnouts and the use of frog juicers makes them electrically virtually gap-proof. Short wheelbase switchers move through the "juiced" turnouts without hesitation.
Installation is easy and goof-proof. The only soldering is on the end of the wire connected to the turnout frog tab. All other connections have screw terminals.
