    100 kVA 3 phase Industrial AC Automatic Voltage Stabilizer

    5 out of 5 based on 3 reviews | Write a review
    100 kVA rated capacity air-cooled AC voltage stabilizer is 3 phase 4-line with 175V-265V (phase voltage)/304V-456V (line voltage) input voltage range, 380V output voltage. This series automatic compensated power voltage stabilizer can keep output voltage stable when outside power supply network fluctuation and load change resulting in voltage waving.

    Industrial Voltage Stabilizer Inner Detail

    3 phase voltage stabilizer details


    The wire connected to the voltage stabilizer should have enough cross section, so as to prevent heating and reduce pressure drop. The voltage stabilizer with a capacity above 2kVA should adopt the terminal connection and a single copper wire should be adopted. Meanwhile, terminal screws shall be fastened to prevent the connection from heating.

    No matter the single-phase or three-phase voltage stabilizer, the load power switch shall be firstly turned off after connecting all wires, then turn on the voltage stabilizer. After confirming the output voltage is normal, turn on the load power switch.

    Existing reviews of 100 kVA 3 phase Industrial AC Automatic Voltage Stabilizer
    Some question about AC voltage stabilizer
    Thank you for your quotation for the AVS (we will locate a suitable input transformer).
    Although the theoretical peak demand of the residential panelboard is 72kVA, the typical local residential demand profile for the size of the home seldom exceeds 50% of this rating.
    Another concern is the cost of US$2,465.44 for no-load AVS losses (5% x [150kVA÷ 0.8] x 730.5hrs/mth x US$0.36/kWhr-mth).  The home is being constructed at the moment where possible please provide the following information to assist in the evaluation of the 150kVA and 100kVA models AVS:
    No-load losses
    Audible sound levels in dBA @3m (or other)
    You will be contacted by the purchaser Mr Yarde regarding the order for the AVS as soon as its evaluation has been completed.

    OK, noted.
    The noise of the voltage stabilizer is 50-60 dBA.
    Can you provide 100kVA voltage stabilizier with 600V (+ / - 30%) input an 480V output?
    I saw the specs table mentioned above 380V output, the input voltage range is  + / - 15%. And can you provide the 100kVA voltage stabilizier with 600V ( + / - 30%) input an 480V output? I really need a device that meets these parameters for my project.

    Yes, we can customize.
    Stable output voltage, good quality
    Delivery was arrived on time. Product with stable output voltage and good quality, it is working like a charm. I will update as times goes on. Will recommend store to other customers who will like to buy 100kVA automatic voltage stabilizer.
