So you are at or over the edge of what the ST is rated for (3 amps), and well under it's 7 amp peak. I still don't know what that means - what is "peak"? if 3 amps is RMS then the peak is 3 x 1.414... (4.2...amps). What does 7 amps mean, exactly? RMS is just a way of time-averaging current, and it'...
