universal phase angle trigger module AFM-11 x10221 introduction this single phase or phase to phase trigger module uses variable phase angle control with adjustable signal matching, selectable soft start and integral current limit input. the pulse train output is reliable, powerful and universally applicable to resistive or inductive loads. the power transformer is remote for increased reliability and wide operational voltage capability. adjustable current limit allows feedback control and via a few external parts, this can also give voltage or speed control of ac or dc loads. the module is fully enclosed for safety and eligibility in industrial environments. applications applicable to most ac or dc, resistive or inductive loads via thyristor, triac or hybrid diode stacks on single phase to neutral or phase to phase supplies, within voltage limits. features fires triacs or thyristors up to 480v, 50/60 hz supplies. selectable soft start function. adjustable current limit control. pulse train firing via isolation transformer. consumes under 2 watts. installation
