I assume the blanket is directly mains powered. I've never really liked
mains wires near my body, even if they are switched off. I remember many
moons back somebody came up with one that operated at about 30 volts via a
psu. Never did know if they caught on though.

I only ask because I'm making up a controller for one. I don't find
the 3 heat settings provide enough choice so I'll be controlling a
small triac via a PWM chip. Although the max current draw of this
appliance is only 350mA, the triac (a Z0607) is pretty puny and I
don't want it operating at too close to its max ratings obviously. I'm
using a snubber to be on the safe side WRT to back EMF anyway.

Here's the datasheet for the triac:

Will that do it or is something more meaty required?


I'd say it was mostly resistive....
sure it's 'sort of' a coil - but a big flat one!

Yes, that's my feeling too, the inductance will be tiny and
effectively non-existent at 50Hz.
