How does AVR categorized?
A3. AVR are mainly categorized into two types, Relay controlled tap changing type and Servo Motor Type. Difference between Relay type and Servo Motor Type: Relay type response more quickly than servo motor type, but servo motor regulator the output voltage more precisely, up to 3% tolerance in precision other than 10% in the relay type. Also, in kebo AVR range, we also categorize by display into meter display type and digital display type.
