        Interesting, one more bit of knowledge, thanks ;o)

        This is something I didn't know

        I'm looking now for another approach: Using 2 relays of 24VDC in series=
 (so, 48VDC) and using a wire wound power resistor and a diode. It will be=
 activated thru an opto-triac. I think it will work. I'll test tomorrow ;o)

        Thanks anyway!
