Cheap and high quality 10 kVA Single Phase AC Automatic Voltage Stabilizer for Home used with input voltage range 95-125V/ 190-250V, 110V±6%/ 220V±3% output voltage, time delay relay modes, is easy to install and operate, protects the equipment or electronic appliances against voltage fluctuation.
Tips: Safety device of the voltage stabilizer
The voltage stabilizer below 3 kVA uses fuse for overload or short circuit protection, and the ac voltage stabilizer above 5 kVA uses small circuit breaker or small air switch for overload or short circuit protection. When the voltage stabilizer is working, if fuse is blown or automatic air circuit breaker trips, it should be shut down to check the load and the voltage stabilizer.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.
