The Universal Dual Frog Juicer automatically and instantly switches the polarity of the frog as an engine passes over any DCC powered turnout. No more complicated wiring or electro-mechanical switches are needed. Instead, you connect power to the Frog Juicer and a single wire to the frog. The Frog Juicer takes care of the rest!
The New Universal Dual Frog Juicer works with all DCC systems, including NCE PowerCab!
Each Dual Frog Juicer can control the polarity of DCC power for two frogs, a reversing loop, a turntable, a wye, or a crossing. It can also be used as a circuit breaker to control a power district (with a bonus, it will reverse polarity if needed).
It uses the same basic design as the hex frog juicer but has 33 Amp transistors so that it can be used with multi-unit lashups and 10 Amp boosters.
The setup is simple: connect the input to the DCC track bus, and connect the output wires to two frogs or rails.
- Eliminates the need for mechanical switches to switch the frog polarity when the turnout is switched
- Instant switching means no interruption to the engine or loss of sound
- Significantly simplifies frog wiring – especially for crossings and double crossovers
- Compatible with any DCC system (Sorry, it will not work with DC)
- Simple to connect
If you have ever struggled wiring up the frogs on a switch, seriously consider using the Hex Frog Juicer. It is simple to use and just plain works.
How The Dual Frog Juicer Works
The Frog Juicer consists of two microprocessor controlled SPDT electronic switches. Each switch can sense and control the polarity of one frog. 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 4 Amps typically work best for an auto-reversing application. The frogs must be electrically isolated and have no other connections to the track or DCC system.
