A voltage regulator converts incoming AC or DC power to the required type and voltage, thereby protecting and ensuring a constant voltage supply throughout the circuit. A voltage regulator is designed to operate at a predetermined power rating (i.e., voltage and current), typically taking a higher input voltage and outputting a lower voltage through feed-forward control or negative feedback. Whether you need a single-phase voltage regulator or a three-phase voltage regulator, Surplus Record is your one-stop solution for all your voltage regulator needs!
