TOBTAK AVR series dynamic voltage restorer use supercapacitors, lithium-ion batteries and other components as energy storage components, adopting advanced power electronic conversion technology and digital control technology to provide short-term energy storage backup solutions to effectively control voltage sag, voltage swell, short-term interruption and other issues, with strong stability, high reliability, high efficiency and etc.
● Fast response, typical response time is less than 2ms;
● Flexible compensation time, typical compensation time is 3s, more backup time can be customized according to customers’ requirements;
● Using the super capacitor as energy storage component, the number of charge and discharge times can reach 1 million times;
● Redundant design of equipment to achieve high reliability;
● Control voltage sag, voltage swell, short-term interruption and other issues simultaneously;
● Full power design of inverters, supporting 100% drop of three-phase input voltage;
● The target value of voltage adjustment can be set on site, and the default value is from -15% to 15%;
● The efficiency of the electronic bypass working state is over 99%, which greatly reduces the cost of power loss;
● Free of maintenance and attendance, saving labor costs.
AVR series dynamic voltage restorer is suitable for semiconductor manufacturing, petroleum and petrochemical, chemical, automobile manufacturing, precision processing, pharmaceutical, paper, medical and health, scientific research institutes, tobacco, ceramics, metallurgy, steel, printing, glass, textile and other industries which require strict power quality.
