Description
The online voltage regulator OLIVER provides effective and efficient voltage regulation when processes in industrial or commercial operations require a clean, immediately available and continuous power supply. OLIVER is an inverter-based system that protects sensitive loads in industrial and commercial applications from voltage-induced disturbances. OLIVER which provides fast, precise correction of over- and undervoltages as well as continuous voltage regulation and load voltage compensation, has been specially designed to protect downstream equipment from mains voltage problems
OLIVER uses a booster transformer connected in series with the load. The two inverters that are not on the current path between the load and the mains supply additional voltage via a booster transformer or reduce the voltage as required for continuous, efficient and precise voltage regulation. In addition, the OLIVER has a redundant internal bypass that ensures uninterrupted power supply via the mains in the event of an overload or internal fault.
