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

1x 6600, electronic speed regulator.

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

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