Hi Good day Marek! This behavior is normal and expected for relay-type AVRs. Minor voltage variations within the ±7% range are acceptable and safe for common household and office appliances, which are designed to operate properly within this voltage tolerance. Since relay-type Automatic Voltage Regulator. For this type of AVR, the output voltage has a ±7% regulation range, which means the output voltage depends on the input voltage condition and will not remain exactly at 220V at all times. If you notice very large or abnormal voltage fluctuations beyond this range, please let us know so we can further assist you.
