Its structure consists of a contact type self coupling voltage regulator, servo motor, automatic control circuit, etc. Whenthe power qrid voltage is unstable or the load changes, the automatic sampling control circuit sends a sianal to drive theservo motor, adjust the position of the carbon brush of the self coupling voltage regulator, and adjust the output voltageto the rated value and reach a stable state.
This series of voltage regulators is a regular type with advantages such as a wide variety, complete specifications, andbeautiful appearance. lt has the characteristics of waveform distortion free, feasible performance, and long-termoperation, and is ecuipped with overvoltage protection function, According to user needs, protection functions such asundervoltage and delay can be set, it can be widely used in any electric field and is an ideal regulated power source.
