OSKAR – Voltage stabilizer
dynamic, adaptive

Stabilize voltage and avoid disturbances

OSKAR – Active voltage stabilizer

Continuous voltage control of overvoltages and undervoltages

Voltage dips occur when large powers are switched on, due to plant faults or already in the public power grid. They often cause significant operational problems. The OSKAR mains voltage regulator provides a remedy and protects your operating grid from overvoltages and undervoltages by continuously regulating the voltage.

The OSKAR is easy to use and is based on an inverter system that protects sensitive industrial and commercial equipment from voltage-induced operational disturbances. It provides fast and accurate compensation for under- and overvoltages, as well as continuous voltage regulation and compensation for load-related voltage changes. OSKAR meets the required system safety for the expected voltage drops in AC power grids.

OSKAR is at an efficiency of more than 98% for loads of 300 kVA. Likewise, it regulates the line voltage within +/- 10 % and eliminates unbalances in the supply voltage.
