DCC Specialties DCC Specialties Frog-AR Quad Output Frog Auto-Reverser

The Frog-AR is a quad frog auto reverser designed and built by DCC Specialties. It is easy to install and will automatically adjust the connected frog [up to four] to the correct polarity. Each frog can be independently set to operate at 1, 2, 3, or 4 amperes. Unlike other frog controllers, the set current not only determines when to switch the frog polarity, but it also is the maximum current that the Frog-AR will allow to flow to the frog. Limiting the trigger current significantly reduces wear and tear on engine wheels and pickups. The Frog-AR can also be configured to control one or two reverse loops.

    – Eliminates the need for aux contacts and mechanical linkages
    – Compatible with low power boosters such as the NCE PowerCab, NCE Twin, and MRC Prodigy Express.
    – Limits current during the reverse cycle – no interaction with circuit breakers
    – 1, 2, 3, or 4-ampere current settings
    – Can control 4 frogs, or 2 frogs and a reverse loop, or 2 reverse loops
