The PSXX series is a product of Larry Maier's years of research and experience into problems dealing with false overloads that cause premature shut down of DCC Boosters and other Circuit Breakers. These false overloads are caused by large capacitors used in sound systems, decoders and lighted passenger cars. The overload appears as a short circuit until the capacitors are charged. The PSXX Series determines if the load is a true short or just an overload due to a discharged capacitor.
