Märklin H0 - 6600 - Model train control unit (1) - Electronic speed controller

1x 6600, electronic speed regulator.

The Märklin 6600 is an electronic regulator for analogue operation, which is used in combination with an analogue transformer such as the Märklin 6611 or Märklin 6631.
With this regulator, analogue trains can accelerate and brake smoothly, and a dwell time can also be set (pause timer).
With the 6600 regulator, the delay, stop and start times can be set by the user.

Warning: The Märklin 6600 only works for analogue operation.
Locomotives with a decoder cannot be used in combination with the Märklin 6600.
