    50 kVA Single Phase Automatic Voltage Stabilizer

    1-phase voltage stabilizer is 50 kVA capacity, automatic stabilize input voltage range 95-125V/ 190-250V AC to 110V±6%/ 220V±3% output. It has excellent features, such as small waveform distortion, high efficiency, high power factor, free from the effect or frequency variation of supply.
    SKU: ATO-AVS-1P50K
    Delivery date: 10-20 days

    50 kVA Single Phase Fully Automatic Voltage Stabilizer consists of a contact voltage regulator, electric servo motor and auto-control circuit as well, auto-sampling circiut sending out signal so that to run servo motor, and to adjust the position of carbon brush, it will ensure output voltage steady operations.


    • Wide input voltage: 95-125V/ 190-250V AC or customize
    • The high accuracy of the output voltage: 110V±6%/ 220V±3%, other voltages can be customized
    • High technology: Programmed control computerized
    • Perfect protection function: Over/low voltage protection, over-heat/load protection, short circuit protection
    • Fashion design: LCD display which can show all protection functions i.e input voltage, output voltage, temperature, delaytime, loading, fault indication and so on.

    6 tips for using a AC voltage stabilizer

    Because of the complexity of urban power supply environment and high power load, in order to make the power supply system operate normally no matter when the power consumption is low or high. AC voltage stabilizer plays a good role in the stability.

    In real life, many people do not understand the precautions in the use of the voltage stabilizer. Here is a brief description:

    1. The AC voltage stabilizer should avoid violent shaking in use.
    2. In order to maintain its normal operation, the AC voltage stabilizer should be equipped with enough capacity of connecting wire.
    3. In order to ensure the safety of the AC voltage stabilizer in use, the grounding wire cannot be removed.
    4. The AC voltage stabilizer should be maintained regularly. The output accuracy of the AC voltage stabilizer will be affected by dust accumulation.
    5. In the process of using the voltage stabilizer, if abnormal operation is found, the power supply shall be cut off immediately to check the cause.
    6. When debugging the AC voltage stabilizer, the load should be increased gradually and observed closely to avoid overload during the test.
