Hi all; In laying out how I am going to cnc this GO704, its apparent that the scr or triac board it comes with to control a motor of undetermined power, rated variously as 750 watts, 1kw, or needing 12 amps from the line. None of which groks, but welcome to chinese specs seems to be the operative response. :)
Anyway, since Jon's pwm servo amplifier worked so well on my lathe, and its theoretically capable of that sort of power (20 amps at 160 volts IAACS), my mind is made up to use it again. But its I/O is not all isolated so it must have an isolated power supply. But 1kw and up isolation cans are both scarce, and north of a $100 bill pricy at least on fleabay. Has anyone got something laying around getting dusty that could serve as a 120 to 120, or 240 -> 120 isolation, and that you might be able to part with? I have 240 just 7 feet away from where I have it parked so a stepdown would work just as well and would help balance the load. Send me PM's with what it is & how much you'd need and lets see if we can deal? Thanks. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
