Voltage quality problems, including voltage dip, voltage swift, voltage imbalance, voltage flicker, and among others, have severe impact on industrial manufacturing. Voltage dip, commonly known as “interference electricity”, refers to the phenomenon when voltage effective value has a sudden decrease and then returns to norm in short time. AVIC-Tech AVR Series active voltage restorer, with power electronic technology to supervise and correct voltage, can rectify voltage dip and swift in a rapid and accurate way, so it has uninterrupted on-line regulation to safeguard industrial manufacturing.
●Wide correction range, three-phase lower to 70%, single-phase lower to 60%;
●Rapid response speed, full compensation time less than half period of power grid;
●Large uninterrupted operation efficiency, least power dissipation at normal AC supply;
●No battery energy storage, less operation maintenance, low operation costs;
●Connection with power supply and load by using transformer, no influence to original power supply system when failure occurs;
●Adoption of three-phase full bridge IGBT rectification technology at input end, power factor >0.99, input harmonics <3%.
AVR active voltage restorer is widely applied in industries strict with voltage quality, such as precision machining, petro-chemical, car manufacturing, semiconductor, and scientific research institutes, etc.
