Automatic compensator Oxygen Zero K

Product type
Micro-interruption compensator

Summary
Oxygen Zero K is a micro-interruption compensator designed to maintain output voltage accuracy and protect critical loads from voltage disturbances. It uses IGBT technology combined with supercapacitors for voltage regulation and provides fast correction times (<5 ms) suitable for sensitive equipment.
