Voltage Stabilizers
Voltage stabilizersare intended to maintain the value of the voltage stable when there is alteration in the voltage of the supply grid, the load resistance, the frequency of the supply grid or the parameters of the environment (temperature, humidity, air pressure, etc.). The main reasons for the instability of the output voltage are the changes in the input voltage and the load resistance. Sometimes these changes happen very fast (in milliseconds), therefore stabilizers must act quickly. The basic parameters of voltage stabilizers are the rated power of the stabilizer, which must be at least 20% greater than the power of consumers, the speed of response and the accuracy. We should pay special attention to the fact that when the load is inductive or capacitive, the stabilizer can manage three to five times smaller load.
The device is used in regions where the input voltage has large fluctuations (160 -250V). After the stabilizer the output voltage is always 220 VAC + / - 2%
