    Yes I agree Erring on safe side is best but it will give him a clue to what the supply is doing which he doesn't have NOW. Esp if he checks over a time period.!

    I think the 33vac will be fine because the G540 Gecko can handle more than 50Vdc for short bursts and it's very unlikely you'll ever get near that voltage.
