Description
Electromechanical voltage stabilizers use a toroidal transformer (variable transformer), a BUCK-BOOST transformer and an electronic circuit that controls the rotation of the variable transformer, thus regulating the output voltage. With the control system, in a very fast response time, the high torque regulation motor adjusts small voltage variations very quickly. The servomotor is taken out of service by the limit switches when it is out of its operating limits and by the control circuit when the output voltage is automatically adjusted to the set value. When the adjustment is complete, the motor energy is cut with the help of an electronic opening circuit, operating in maximum silence. The system is equipped with a bypass switch that allows you to power the load with the mains voltage in case of malfunction or need. By using the setting buttons, it is possible to adjust the output voltage, the precision range, the regulation speed, and the high-low voltage limits. It is then possible to adjust the maximum current control and the relative hysteresis time. All settings can be password protected. A display shows the input and output voltage, and the current supplied.
