This DCC Booster was designed to solve two issues that putting a lot of DCC accessory decoders on your layout brings up. 1) They are a drain on your precious loco amps and 2) When a loco causes a short all the accessories lose power. To solve this problem we have made a DCC booster that can be used for accessories on any brand of DCC system. It can provide about 5 Amps of power to run the DCC accessories independent of the track power from your command station. During a short on the layout, when the DCC signal dies, the booster continues to deliver full power. This is a so-called "dumb" booster in that it does not need a cab bus - it connects directly to the track output of your existing command station.
You can also use the booster as a "powered circuit breaker". It fills all the functions of a circuit breaker but provides its own power. Each of your power districts puts no load on the command station as it is fully buffered. I use several of these with 16 V power supply which gives about 14.5 Volts on the track to power my own layout with just a single NCE PowerCab.
Auto- shutdown - the unit shuts down after 5 minutes of no DCC signal (accessory mode) or immediately (power district mode). When the DCC signal returns it wakes up immediately. Just plug the booster in and forget about it.
The booster has protection against shorts and overheating. The input is optically isolated.
Efficient - this booster uses the latest in efficient power electronics and as such it does not get hot in normal operation - the power supply is a highly efficient switching power supply that also stays nice and cool. A heatsink is provided although in normal use it never becomes warm unless the track is continuously shorted.
DCC Booster board without the power supply. These boards can be used to make locomotive Power Districts or an Accessory District with a shared power supply. A jumper is used to set either Accessory Mode or Power District Mode. Each board can supply up to 3 Amps continuous duty and 5 Amp peak with a suitable power supply. These boards work very nicely with the Hex Frog Juicer.

DCC Connectors: Screw blocks Max output: 5 Amps for short periods, 3 Amps continuous
Output voltage: Supply voltage minus 0.8 volts - independent of input voltage

TurnOn Module - Soft Start Circuit For Large Inrush Currents of Sound Decoders and Stay Alive Decoders If you have a lot of sound decoders and decoders with stay alive circuits on the track, they can confuse the booster when it starts up in to thinking there is a short because of the sudden current draw of all the capacitors. This circuit prevents that problem by putting a small resistance in to the circuit to slow the current rush and once the voltage gets up a 10 Amp relay bypasses the resistor so that there is a straight connection to the booster. If you have no idea what the previous explanation about and you are not having any touble with starting your layout then you don't need the TurnOn.
Note: will not work if the final load is over 60% or so of the capacity of the command station. I.e. if you have a 5 Amp command station and are trying to run a 3 Amp load of locomotives, or more, then the TurnOn may not work. In this case you proabably need more power or use toggles switches to turn off some of the tracks with idling locomotives.
Connect the TurnOn directly after the booster and before any other components.
Resistor is 0.5 Ohms 20Watt. Relay is 10 Amps and turns on at about 10Volts on the track. Diodes prevent the startup pulse of the relay from getting on to the DCC bus.
Will also work with other brands of boosters and command stations.

DCC Polarity Reversal and Power Routing (Frog Juicers)
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 have both been modified to work with Peco electrofrog turnouts (and other power-routing turnouts) as they come. You still need to insulate the Peco electrofrog turnouts as in the instructions that come with the turnout. Peco Insulfrogs do not need a frog juicer as the frog is plastic and cannot be powered.
DCC Mono Frog Juicer (polarity reverser for frogs)
For all DCC systems including NCE PowerCab. This board is an automatic polarity reverser for a single frog. Setup is simple, connect two wires to the DCC bus and one wire to a frog. The frog should be fully isolated. When a train crosses the turnout and the frog is the wrong polarity, the frog juicer will reverse the polarity so quickly that the train and the rest of the DCC system will never notice. Should not be used with boosters over 5 Amps. See the Dual Frog Juicer for 10 Amp boosters.

How to wire the Mono Frog Juicer to a "DCC-friendly" turnout.
(Note: be sure both DCC connections are in the same power district.)
DCC Dual Frog Juicer and Auto-Reverser
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.

DCC Circuit Breaker version of DFJ
This is the same board as the Dual Frog Juicer but is confugures to work as a circuit breaker. When there is a short it will cut off both rails at once. This solves some problems where only one rail is cut off and wheels bridge to another active rail. Also the auto-reverse has been disabled - this gets around the issue of having an auto-reversing section and frog juicers within the district powered by the circuit breaker. Cut off current limit can be set to either 2 Amps or 4 Amps with jumpers. LEDs have been changed to indicate green for normal operation and red for a short. You can also add a remote LED to indicate a short. It has 33 Amp transistors so it can be used with 10 Amp boosters. Setup is simple, connect the input to the DCC track bus, and connect the output wires to the district to be protected.

DCC Hex Frog Juicer
For DCC systems 2 Amps to 8 Amps including NCE PowerCab. This board can be configured to use as an automatic polarity reverser for six frogs, or a reverser for one to three reversing loops, turntables, wyes, or crossings. Setup is simple, connect the input to the DCC track bus, and connect the output wires either to six frogs or rails. Two jumper controls whether the two, four or six outputs act as pairs (i.e. an auto-reverser) or independently (i.e. a pair of frog juicer). Should not be used with boosters over 10 Amps. See the Dual Frog Juicer for 10 Amp boosters.

What happened to the PowerCab versions?
By a small tweaking of the design the newest versions of the frog juicers work with the NCE PowerCabs.
