TNSTA series three-phase oil immersed voltage regulator (100K-4000K)

The AVR11 series voltage regulator is an upgraded version of the SVC series voltage regulator with more complete protection functions. When the voltage of the power grid is unstable or the load changes, the intelligent control circuit automatically samples the control circuit and sends a signal to automatically adjust the voltage, so that the output voltage is adjusted to the rated value and reaches a stable state. This product has the characteristics of waveform distortion, reliable performance, and long-term operation. It is equipped with overvoltage protection function. According to user needs, protection functions such as undervoltage and delay can be set up

Product Features

  • The structure is solid, heat dissipation efficiency increases, recycling and reuse rate is high

  • Continuous no stage voltage regulation design: adopt no voltage adjustment, the output voltage is linear voltage control, the output voltage is no noise interference, the waveform is not distorted

  • Digital internal module, double backup control, abnormal alarm: when the main control element is abnormal, it is automatically converted to the backup component, the regulator still works normally, and more protection

  • Digital control panel monitoring, touch button: LED input and output voltmeter, load ammeter, when the input voltage or voltage regulator is abnormal, warning device alarm, the corresponding indicator     

  • light on the panel, a variety of abnormal conditions at a glance, can also be connected to the external signal to the trip switch, do automatic power off function.
