80 kVA Voltage Stabilizer Features
- Input: Three phase and four-line system, 175V-265V (phase voltage), 304V-456V (line voltage)
- Output: Three phase 380V, other voltages can be customized
- High technology with computer programming control
- Comes with a sleek, compact, and elegant design
- Perfect protection function: Over/ low voltage protection, overheat/ load protection, short circuit protection
- High efficiency: More than 95%
80 kVA 3-phase Industrial AC Automatic Voltage Stabilizer is applied when the power network voltage fluctuates or the load current varies, it automatically regulates the output voltage to ensure the normal function of the varied electric equipment.
It has the advantages of large capacity, high efficiency, no wave distortion, stable voltage adjustment, suitability for different kinds of loads, bearing instantaneous overload, and working continually for a long time. It is provided with protection against over voltage, over current, phase failure, and protection for phase sequence.

8 maintenance tips of three phase voltage stabilizer
- Do not operate under overload, and try to stagger the peak load.
- Clean up the dust and disconnect the power supply of the power supply before maintenance to ensure safety.
- Whether the installed model meets the environmental requirements, if not, please improve.
- Carefully clean all parts, especially the carbon brush, contact the exposed part of the coil, and remove the dirt.
- Under the installation environment of high-precision voltage stabilizer, ventilation shall be ensured, and the ambient temperature and body temperature shall be normal.
- Before the seasonal conversion, the transformer and high-precision voltage stabilizer shall be thoroughly maintained to remove potential safety hazards.
- Replace the worn or damaged carbon brush in time, and repair or replace the faulty or damaged components in time.
- Check whether the internal parts and wire ends of the high-precision voltage stabilizer are loose. If there is a loose connection or poor contact, handle it in time.
