Hi Andy,
Are you thinking about just replacing the relay
across the resistor with a Triac? Or something more
involved like a phase controlled ramp??
A Triac will exhibit a considerable loss during
normal, post startup, operation. I've seen circuits
where a Triac is used with a relay connected in
parallel. The Triac is first enabled, then shorted by
the relay. This greatly reduces contact wear on the
relay while avoiding the typical 2V drop of a Triac.
73 & Good morning,
