First time of meeting this triac drive rather than protection concept Upping to 90 percent mains the current draw drops from the 0.5 amp of 80 percent maions to .2amp approx and then at 100 percent approx .25 amps, now to test under heavy load
What is the prognosis for PAT/insulation testing of these "magnetic field" amps, knocking out diac/triac etc ? with 3.9M, R8, between ground and one side of the mains transformer. Triac protection ccts are isolated from ground, IIRC, where used in amps.
