Hello tech's,
I think i get a 3kWatt heater challenge to deal with.
Someone asked me if i could make a simple fluid heater control (for a distiller). It should work like a gas stove; when the fluid is boiling too much, just turn the knob a bit down...
I was thinking of a PWM control, but with 3kW?!?
Maybe a very 'slow' PWM control with a solid state relay?
An ssr switches at zero crossing, is that good for a fluid heater? (or: is it a resitive load?)
Or is it anyhow better to use a real pid? -heater control? (example schematics plzz )
I don't have details yet about heater type and distiller size and so, but i'm sure you can point me to the right direction.
Many thanks in advance!
