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.
