    20 KVA Single Phase Automatic Voltage Stabilizer Details

    Existing reviews of 20 kVA Single Phase Automatic Voltage Stabilizer
    Know more about the 1-phase, 20kVA voltage stabilizer
    For your 1-phase, 20kVA voltage stabilizer, we inquire about the specs listed on your website:
    1. It says “adjust time < 1 seconds (against 10% voltage deviation). What is meant by this?
    2. It says “temperature rise < 60 degrees C”. What is meant by this? Is this how much hotter the machine gets when it is turned on?
    3. It says “protection overvoltage < 246  /- 4 V”. What is meant by this? Is this the level at which the machine shuts down and stops working to protect itself?

    ATO Responded
    1. "adjust time < 1 seconds (against 10% voltage deviation)", it mean that the stabilizer adjustment time <1 second, when the input voltage change rate is within 10%.
    2. Yes, when the machine is working, "temperature rise <60 degrees C".
    3. Yes, it's the level at over voltage in which the machine will switch to the grid, but it will not stop working.
    Great automatic voltage stabilizer, worked as my expected!
    Great automatic voltage stabilizer, worked as my expected! We don't normally write reviews but this item and ATO website were both great to work with. They answered all our questions in a short time. We would recommend this item and the website to anyone who wants a voltage stabilizer that is limited.
