3 Phase AVR (20kVA-100kVA)
Application
A voltage regulator /Stabilizer designed to automatically maintain a constant voltage level; Single/three-phase compensated voltage stabilizer is a contact-adjustable, automatic voltage compensation, high-power regulating power device. When voltage from the support network is varied due to loading current effects, it automatically regulates the output voltage to ensure the normal function of the varied of electrical & electronic pieces of equipment
This series can be widely used in industry, agriculture, transportation, post and telecommunications, military, railway, scientific, cultural and other fields of printing equipment, metal processing equipment, production lines, engineering equipment, elevators, medical equipment, computer room, computer control equipment, embroidery, textile equipment, air conditioning, radio and television, hotel and household appliances lighting need to be regulated.
Main Features
- Large capacity, high precision
- Adopted compensated voltage technology
- Wide input voltage range
- Over-voltage protection
- Output voltage three phase auto-balance (individual control)
- With bypass system
