1. Multiple Power Districts Using SBOOST If more than one SBOOST is to be connected between the command station e g one of the SPROG family and the layout to give multiple power districts then care must be taken with both the DCC input connections and the track connections to ensure the same polarity at each SBOOST Connect all of the SBOOST In A terminals together and connect to one output of the command station Connect all of the SBOOST In B terminals together and connect to the other output of the command station Connect the Tr A and Tr B outputs to the layout in a consistent manner in each power district E g connect Tr A to the left rail in each power district and connect Tr B to the right rail in each power district BOTH rails MUST be gapped between power districts The SBOOST track Outputs must only be connected to their own power district i e there must be NO common wiring between power districts lf a single power supply is used to power more than one SBOOST it must be rated to supply the maximum current to all SBOOST simultaneously E g for two SBOOST the power supply must be rated at greater than 5 Amps If separate power supplies are used to power multiple SBOOST then they should all be of the same type and voltage rating The OV connections of all Version 1 4 February 2012 Copyright 2012SPROG DCC SBOOST User Guide 6 the SBOOST must be connected together This is sometimes2. supply power to the SPROG II See below see the picture below Connect the SBOOST DCC inputs In A and In B to the SPROG II track outputs Powering a SPROG II all versions There are two considerations to be taken into account when powering an SBOOST and a SPROG II from the same power supply The electrical isolation between the layout and command station i e SPROG Il will no longer be effective The SPROG II has a lower maximum supply voltage of 15V compared to the SBOOST maximum of 20V When using an SBOOST with a supply voltage greater than 15V special care must be taken For SBOOST supply voltages above 1 V a separate power source of the correct voltage should be used Version 1 4 February 2012 Copyright 2012SPROG DCC SBOOST User Guide 5 for the SPROG II For SBOOST supply voltages in the range 15 17V you can use a separate power supply or insert a string of 3 1N4001 or similar diodes in series with the V connection to drop the voltage slightly Connect the SBOOST V output to the SPROG II V input Connect the SBOOST OV output to the SPROG II 0 input Connection to a SPROG 3 Follow the connection instructions for SPROG II The SPROG 3 is rated for the same maximum voltage as the SBOOST and can always use the same power supply lf electrical isolation is required between the layout and SPROG 3 then a separate isolated power supply must be used Connection to Other Command Stations TBD
