DCC Specialties PowerShield X-1 Block

The PSXX has a default trip rate of 2.0 amps

    The PSXX series has the most reliable operating features that protect model railroad equipment and wiring from damage during a short circuit, including fast-acting, solid-state electronics.

    The PSXX circuit board is wired between the DCC system?s booster and the track bus.

    The PSXX includes screw terminals for easy connections from the booster and to the track. There is also an extra pair of terminals for linking the booster power input wires to additional PSXX breakers should you need to add extra PSX protected power districts.

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.
