Tips: Overvoltage protection of the voltage stabilizer
When the output voltage exceeds the voltage stabilizer protection value (the phase voltage protection value is adjusted to 250V±5V at the factory), the voltage stabilizer will automatically protect, reduce or cut the voltage output voltage of the stabilizer, and the over-voltage indicator light will be on, the user should immediately shut down to check the grid voltage or the voltage stabilizer. When the voltage stabilizer is working, if the output voltage is jitter, it may be capacitive or the inductive load is too heavy. The user can adjust the switch on the circuit board in the case to eliminate the jitter (please turn off the load when adjusting). If the shaking cannot be eliminated, it may be caused by too much internal resistance of the input grid line or serious distortion of the input waveform.
If the voltage stabilizer is under overvoltage protection after starting, please check whether the stabilizer is adjusted normally and whether the grid voltage is out of the range of the voltage stabilizer. Switch on the voltage stabilizer and turn on the electrical equipment after the output voltage is stable.Visit blog post Safety Tips for Using Voltage Stabilizer.
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.
