Dew Control in Getting Started Equipment Help and Advice Posted February 3 1 minute ago, KP82 said: The dew strips are designed to operate at 12V DC. If you plug them straight in the mains without any transformer, I believe they would just burn out (unless you make your own strips with appropriate wires I suppose). A dew controller can help control the power output so you don't overheat part of the tube causing air current. I'd go for a 12V 10A supply instead of 5A just to be sure there is enough power. Hi, Sorry, what I meant was, straight into the mains via the adapter https://www.amazon.co.uk/Cigarette-Lighter-Adapter-110V-240V-Converter/dp/B07BHNGFGV So for 12V 10A, I would need a different controller and adapter?
