Automatic overvoltage and undervoltage
protection
When the output voltage is less than 180V or higher than 250V,
the stabilizer will cut off the output voltage. The HIGH/LOW
LED indicator will turn on.
When the input voltage returns to normal, the stabilizer will
reactivate the output voltage according to the set delay.
Overload/overtemperature protection
The stabilizer has a special circuit that offers protection in case of
overload or overtemperature. When the indoor temperature
exceeds the factory default value, the stabilizer will cut off the
input voltage and turn off.
Automatic adaptation to the input frequency
Thanks to an integrated system controlled by a micro-computer,
the stabilizer automatically identifies the input frequency (50Hz
or 60Hz) and adapts to it to meet the output voltage needs.
