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. Max power supply voltage: 40V Power Connector: 5.5 mm (outer)/ 2.1 mm (inner) barrel plug, center positive DCC input: optically isolated, 5-24 Volts (voltage level on the DCC input pins has no effect on output voltage level), 25 mA load typical. DCC Connectors: Screw blocks Max output: 5 Amps for short periods, 3 Amps continuous Peak-to-peak output voltage: Power Supply voltage minus 0.8-1.4 volts (decreasing with load and independent of voltage on the DCC input) Short Trip Point: 5.6 Amps Short Trip Off Time: 1 microsecond Short Trip Recovery Time: 200 microseconds No Auto-reverse Board Size: 3" long x 2.5" wide x 0.5" deep (including heatsink) (76mm x 64mm x 12mm). Green blocks extend another 0.3" (8mm).

Pololu Pushbutton Power Switch SV (old version)

14.5V 5A Power Supply for HO Scale Track Power Use 14.5V 5A 72.5W switching power supply. Best for HO track power.  Delivers about 14.2V to track when used with TVD-DAB002 Booster.  Plug size is 5.5/2.1 mm. Power supply comes with a US 110V plug.  By swapping the power cord can be used with 100-240V~50/60Hz power. If you add the TVD-JCK001 screw terminal adapter you can use this as a general purpose power 14.5V supply.  

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. 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.
