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
  • 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
