The voltage stabilizer has an input voltage adaptation range. According to the IEC standard, the input voltage can vary within ±20% of the rated value. If it exceeds this range, it will automatically trigger an audible and visual alarm, and it cannot maintain the output voltage within the required range.
2. Output voltage regulation refers to the effect of output quantity change caused by input voltage variation. When the load is at its rated value, adjust the input voltage from the rated value to both the upper and lower limits of the source voltage range, and measure the large change in output voltage (±). The smaller this value, the better, and it is an important indicator of the performance of AC voltage regulators.
3. Load Adjustment Ratio: This refers to the effect of output quantity change caused by load variation. By altering the load current magnitude, the change in output voltage (±) is measured. The smaller this value, the better, and it is an important indicator of the performance of AC voltage regulators.

4. The relative harmonic content of the output voltage (also known as the output voltage distortion), typically represented by THD, is the ratio of the total effective value of harmonic content to the fundamental effective value. When the load is at the rated value and the input voltage distortion meets the reference conditions (generally less than 3), measure the output voltage distortion at low, rated, and high input voltage levels, and take the highest value. The lower this value, the better.
Efficiency: It is the ratio of the output active power P0 to the input active power Pi (expressed as a percentage).
6. Load Power Factor; 7. Voltage-Ampere (VA) or Kilo-Volt-Ampere (KVA) values are used to indicate the capacity of voltage regulators. These values represent loads with both resistive and reactive (inductive and capacitive) components, meaning they include both active and reactive power. This indicator reflects the AC voltage stabilizer's capability to handle inductive and capacitive loads.
