    3.Characteristics


    v LCD Large-screen

    Using large-screen LCD display, can shows dynamic display voltage, current, and all kinds of working condition.


    v Product Characteristics

    The speed of response time(regulating speed) is very fast, non-contact, anti-interference, no mechanical failure and wear of carbon brush, maintenance-free. Three-phase voltage regulating independently to ensure the balance of output voltage . Effectively protect the security of the precision equipment.


    v Precision (output accuracy) Can Be Adjusted

    All precision of the stabilizer is preset plus or minus 2 Volt. According to different load demand can be adjusted plus or minus 2 Volt, plus or minus 2 Volt.


    v Manual Voltage Regulation

    According to production requirement, within the scope of the 10% rated voltage value, the stabilizer can set voltage arbitrarily for different electrical equipment.


    v Automatic Bypass Function

    Equipped with automatic bypass function, when the stabilizer fails,it can turn into the mains automatically, no affection for the production.


    v Output High and Low Voltage Protection Function

    When monitoring circuit detect the output voltage beyond the upper or lower limit, voltage stabilizer can turn into the mains automatically, no affection for the production.


    v Lack of Phase/Phase Fault Protection Function

    When monitoring circuit detected phase failure, voltage regulator /stabilizer will cut off the output automatically and voice-alarm.


    v Delay Stabilizing Output Voltage Function

    Voltage Stabilizer boot or recover from a state of protection, would not be regulated immediately. But stay on only after users determine that the mains voltage are normal to ensure that the load equipment would not be damaged.


    v Automatic Output Function

    System preset is automatic output. When stabilizer connect to the mains, system detect that the power grid is normal, then it would delay 30 seconds, stabilizing output voltage automatically.


    v Modular Design, Easy to Replace and Repair

    Adopting modular design, regulating circuit and monitoring circuits independent to each other, all components are standard-normalization. Assembly, debugging, maintenance are more simple and quick.


    v Strong Load/Carrying Capacity

    When the short-time overload or short-circuit, the transformer would not be damaged to avoid coil burning fire. When overload 150%, stabilizer can withstand 90 seconds, 20 seconds for overload 200%.

    Working principleDSP digital intelligent processor, the true RMS voltage and current are under real-time detection and control output in a specific order .With relays ON and Off, to change the value and polarity of the compensation voltage. Frequency and voltage and sine wave are in-phase superimposed to maintain the output voltage stability.Via motor to drive the carbon brush position on regulator slide coil to change the turns ratio regulator coil. And then it will changing the compensation voltage of the transformer, so as to stabilize the output voltage.
    Response timeWhen the voltage drop above 5%, just it requires 500ms to stabilize voltage. At the same time, it can quickly suppress the transient voltage surge level, real-time effective protection of precision equipment.Response slow, when the voltage drops above 5%, it is necessary to stabilize voltage within about 1500ms. Due to the lag regulation, it can not effectively prevent the instantaneous input surge voltage .So it is difficult to protect precision equipment effectively.

    1, when the load current exceeds the rated current value of the regulator, the regulator will automatically switch to bypass, and displayed on the LCD screen overload, to remind the user to correct. And it can continue to protect equipment from damage running at high speeds.

    2.When the load current exceeds rated current value of 10%, the regulator will automatically switch to bypass with to reminding the user to correct.And user will have the time to turn off the machine before the input breaker trips off to protect the regulator itself from damage.

    When the load exceeds the rated current, it will trip off automatically . Due to suddenly power off, it may bring heavy damage to the load,which is running at high speed.
