Yes, but I'm not really concerned with that - just adequate.
That's how this one works - but with a degree of hysteresis so it's not fast switching.
Had a senior moment there. I've got the packaging in front of me from the newest one and it says 21VAC, 51W
Surely the opposite? I'd expect the rated voltage at full load, but higher off load? The other slight fly in the ointment is the transformer has two
110 volt primary windings which you series for UK mains, but if at 240 volts that's another 10% or so to worry about.
