It could be but it is a switched mode power supply and not a conventional transformer. It also doesn't have a speed controller and no reverse direction ability.

I don't recall a 6005. Did you mean a 60055? The 6001-6003 were definitely transformers, and the marklin database also describes a 60055 as a transformer for the USA (110v) market, which would not be any use for someone in Sweden.

EDIT: I just found this -> https://wiki.3rail.nl/in...?title=M%C3%A4rklin_6005 It must be more that 25 years sold and is unlikely to be a switched mode power supply. Would it be as simple as hooking this thing up to a potentiometer and driving the analogue trains from that?

It is NOT a switch mode power supply. It is a 60va transformer that was brought out with the cs1 to provide additional power over the older versions that were used with the 6021 control.

You could use it on an analogue layout inconjunction with other components.

The 6005 is perfect for powering lights and accessories that need 16v AC, in an old analogue layout.
That way your 66470 won't need to power lights etc, and will have a little more power for running your trains.

If you wire with a common ground (brown), then take special notice of pages 8 to 10.

Hi Alan,
Don't want to be rude but a 60055 is not switched mode. They were introduced in 2005 long before the switched mode power supplies were available. You can tell because of the weight caused by all the steel and copper windings that make up the actual transformer. I have a bunch and have had them for years. Marklin doc never refers to them as anything other than a transformer.

Regards,
Roger

The original 6005 was not a switched mode supply, but rather a transformer which provided a pair of live and return outputs (Yellow and brown) providing 16VAC which could be used to power a 6021 or accessories, as can be seen here:

I suspect that this was possibly intended as a power supply for the 6604 Delta Controller, which allowed you to select the 4 available Delta addresses and control the speed and direction of one loco at a time.
The later Delta Control 4f had a built in transformer.


I don't know if there was a 120VAC version of this unit. 6005 was the 230VAC version.

The 6604 did not control the speed of the loco, but required a transformer with a speed knob.
The 66045 Delta Control 4f did not have a built-in transformer, but it had a built-in speed knob. An external transformer is required, but transformers without speed knob can be used.
