{"product_id":"marklin-6021-ho-digital-control-unit-ex","title":"Marklin 6021 HO Digital Control Unit EX","description":"Here is a Marklin 6021 HO Digital Control Unit. The Control Unit is the heart of the Digital System. Only one is required for a layout and other control devices plug into it. The Control Unit receives its power from a transformer by means of the yellow (labeled \"L\") wire and the brown (labeled \"O\") wire. Any transformer will work as long as it has a 16 volt fixed AC output, but one that supplies 42 watts, as the 6001 MÄrklin transformer does, would be best. Transformers that give more than 50 watts would not be any more productive since the Control Unit will not output more than 50 watts. The control panels will take about 8 watts to run and each of the engines take no more than 10 watts, so larger layouts will require an additional Booster to power them.\u003cbr\u003e\u003cbr\u003eThis item has been graded per TCA standards C-7: Excellent based on visual appearance.
