- Page 5 NO common wiring between power districts. If 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.
- Page 6 SPROG 3 (or SPROG II) and SBOOST with common power supply. Using a SPROG 3 and SBOOST in this way is not recommended. A short circuit in the SPROG 3 power zone will affect the DCC signal to the SBOOST.
- Page 7 SPROG 3 and SBOOST with separate power supplies. Using a SPROG 3 and SBOOST in this way is not recommended. A short circuit in the SPROG 3 power zone will affect the DCC signal to the SBOOST. Each power supply should be the same voltage.
- Page 8 SBOOST User Guide Example 3 SPROG 3 (or SPROG II) driving multiple SBOOST with common power supply. The power supply must be able to supply the full rated current (e.g., at least 5 Amp for 2 x SBOOST). Power districts must be separated by isolation gaps in both rails.
- Page 9 SBOOST User Guide Example 4 SPROG 3 (or SPROG II) driving multiple SBOOST with separate power supplies. Each power supply should be the same voltage. Each power supply must be able to supply the full rated current, i.e. at least 2.5 Amp.
- Page 10 SBOOST User Guide Auto-reverse Operation The SBOOST can be configured for auto reverse operation, e.g., to supply power to a reverse loop or wye formation as a separate power district. To enable or disable auto-reverse operation you must open the casing of the SBOOST and fit or remove a jumper link.
- Page 11 Auto-reverse operation must not be enabled in adjacent power districts. This may cause “thrashing” as both SBOOST try to auto-reverse simultaneously. For UK customers, spare jumper links may be obtained from SPROG DCC on receipt of a stamped self-addressed envelope. They are also available from electronic component suppliers.
