Powertek make servo provide accurate voltage for your expensive equipment irrespective of the incoming line voltage. Powertek servo’s incorporate sold control devices. Stepper motor operates the auto transformer with buck and boost Transformer. Whenever output voltage changes the Electronic circuit produces an error signal which moves the auto Transformer drive motor and feeds the voltage to primary of buck boost, the secondary of buck-boost is in series with the load so that the secondary voltage gets added or subtracted to maintain the output voltage within 0.5% of the set voltage.
