Single-Phase Static Voltage Regulators

ELSIPOWER static voltage regulators correct mains fluctuations quickly and precisely. Their microprocessor-controlled electronic design responds to voltage changes within milliseconds.

Regulation is performed without a servo motor or moving brushes, reducing maintenance caused by mechanical wear. Semiconductor power elements withstand sudden high currents and support loads with high inrush current.

An LCD control panel shows operating values and allows output voltage and accuracy adjustment. Overcurrent, overvoltage, overload, over-temperature and short-circuit protection safeguard both the regulator and the load.
