UPS (Uninterruptible Power Supply) systems are essential for providing backup power to critical equipment in the automation and industrial sectors. These devices ensure continuous operation during power outages, voltage fluctuations, or electrical disturbances. Common UPS products include online UPS, line-interactive UPS, and standby UPS, catering to different power protection needs. Key features often include surge protection, battery backup, and voltage regulation. UPS systems are widely used to safeguard sensitive electronics, servers, and automation controllers, preventing data loss and equipment damage. Capacities range from compact desktop units to large-scale industrial systems, with options for single-phase or three-phase power.
