with so many posts here about 555 PWM i cannot seem to find what i need. i need simple PWM 555 circuit to drive a triac. triac being used is logic type to keep gate power way down and is rated 10A RMS 800V. triac load will be 60Hz 120vac 1amp. i just need to be sure that the PWM freq is always greater than the 60Hz load frequency, otherwise its possible to chop off the load when it should be on, etc.
will this work without changing frequency (or if it changes does not drop below 60Hz) when varying the pot (aka turn the knob)?
