    Tips: What is a Voltage Stabilizer?

    Voltage stabilizer is a kind of power supply equipment which can automatically adjust the output voltage. Its function is to stabilize the power supply voltage which fluctuates greatly and cannot reach the requirement of electrical equipment within its set value range, so that various circuits or electrical equipment can work normally under rated working voltage. With the increasing number of household electrical equipment, the use of voltage stabilizer is more and more extensive. Domestic voltage stabilizer is mainly used to stabilize the voltage of TV, refrigerator, air conditioner, etc.

    In this video ATO uses a voltage regulator and multimeter to test the output voltage of the 3 kva voltage stabilizer which has 140V to 270V AC input, 220V AC output. After testing, we may see that the output voltage is within 220V ± 6%, which is in line with the standard.
