An Online UPS 6kVA (Uninterruptible Power Supply) is a high-performance power backup system designed to provide continuous, clean, and stable power to sensitive equipment. Unlike other UPS types, an online UPS delivers power without any interruptions, even during a power failure, by continuously converting incoming AC power to DC and then back to AC. This ensures zero transfer time and protects against all forms of power disturbances, including surges, sags, and frequency variations.
