Example 4
SPROG 3, SPROG II or other booster and SBOOST II with separate power
supplies.
Using a SPROG 3 (or SPROG II or other booster) and SBOOST II in this
way is not recommended.
A short circuit in the SPROG 3 power district will affect the DCC signal to the
SBOOST II resulting in the loss of the DCC signal in the SBOOST II power
district.
Each power supply should be the same voltage.
Each power supply must be able to supply the full rated current, at least 2.5
Amp.
A common ground connection is required between the power supplies.
Power districts must be separated by isolation gaps in both rails.
