Industrial Voltage Stabilizer (IVS) - 440V

Nano Power 3 Phase Voltage Stabilizer Features

  • Three phase 4-line 175V-265V (phase voltage) 304V-456V AC (line voltage) of wide input voltage range, 380V output
  • High technology with computer programming control
  • The high accuracy of the output voltage (output voltage can be customized)
  • Perfect protection function: Over/ low voltage protection, over heat/ load protection, short circuit protection
  • High efficiency: More than 95%

Industrial AC Automatic Voltage Stabilizer is widely used in post and telecommunications, department stores, elevators, hospitals, schools, printing, securties and other occasions where all needs normal voltage to ensure, such as workshop mines medium enterprises, some of the important equipment and computer power and support.
