Probably not. May be O.K. for analogue if you add a rectifier and only use the lower 10% of the dial, you don't want 240V on the rails! You could add a 10 to one transformer but IMHO you'd be better getting a conventional model railway controller.Anyone seen this item would it be worth trying?
Yep, it will work well for resistive loads. Just bear in mind no temperature regulation will happen, so it will probably just take longer to warm up to a similar temperature.Would it work for a mains driven soldering iron for lower heat soldering like for white metal?
