What Are The Basic Parameters Of A Dynamic Voltage Stabilizer? What Are They?

Dynamic Voltage Regulator (DVR) is a product for improving power quality. A dynamic voltage stabilizer is a device that changes the input voltage. Its function is to use a voltage of 380V (domestic) and keep it stable. It is widely used in homes, factories, and various projects. Here is a brief introduction to some basic parameters of the dynamic voltage stabilizer:
1. Working frequency: The sampling of the dynamic voltage stabilizer is closely related to the frequency. Most of them are 50HZ in China and 60HZ abroad. This frequency is called the working frequency. The general working frequency is between 50HZ and 60HZ.
2. Rated power: It refers to the maximum load power when the dynamic voltage stabilizer is working. It is the output power of the dynamic voltage stabilizer working for a long time at the specified frequency and voltage without exceeding the specified temperature rise. The unit is generally expressed in KVA
3. Rated input voltage: Single-phase compensated AC voltage stabilizer: 220V. Three-phase compensated AC voltage stabilizer: 380V
4. Allowable input voltage variation range: The allowable input voltage variation range is expressed as a percentage of the rated input voltage, and can be selected from the following values: ±20%, ±30%. Note: When the user makes a request and negotiates with the manufacturer, products other than the above values ​​can be produced.

Rated output current: When the dynamic voltage stabilizer is running under resistive load, the calculated output current value at the rated voltage and rated capacity should be guaranteed.
7. Voltage regulation accuracy: When the input voltage is within the ±20% variation range, the voltage regulation accuracy should be ±3%; when the input voltage is within the ±30% variation range, the voltage regulation accuracy should be ±5%
8. Output voltage asymmetry: The asymmetry of the three-phase no-load output voltage of the dynamic voltage stabilizer should not exceed 5% when the voltage regulation accuracy is ±3%, and should not exceed 7% when the voltage regulation accuracy is ±5%.
