If this voltage is in the range of 190-250V, the regulator provides the 
100% listed maximum output power. maximum output power will change 
as the curve shown below.

OUTPUT: 220V~

6.  LOW & HIGH VOLTAGE PROTECTION

When output voltage comply with labeled voltage, AVR will go into 
automatic recovering state, the UNUSUAL RED indicator extinguishes. 
Then DELAYING ORANGE indicator flashes every one second, the 
system goes into delaying state. After delay, DELAYING ORANGE 
indicator extinguishes and output voltage resume .

When output voltage is lower or higher than labeled voltage, AVR will turn 
into self-protection state automatically ,the UNUSUAL RED indicator 
flashes every one second and output voltage will be cut off.

7. THERMAL PROTECTION

8. OUTPUT CAPACITY

The automatic voltage regulator will switch off automatically if the total 
wattage of the electrical appliances exceed the automatic voltage 
regulator output capacity.

NOTE:  Not equipped overheating Protection in standard configuration, 
users should notify manufacturer and take special order if this function 
is required.

When the temperature of the transformer exceeds 130

+/-5% , the 

system will automatically turn into self-protection state, UNUSUAL RED 
indicator will flash every one second and output voltage shut down. While 
temperature is lower 70

+/-5% , the system will recover automatically. 

UNUSUAL RED indicator will extinguish, and output resume.
