The ATEN Online UPS OL3000HV is a professional 3000VA online uninterruptible power supply (UPS) designed to provide continuous, clean, and reliable power for mission-critical IT equipment. Using true double-conversion technology, it protects connected devices from power outages, voltage fluctuations, surges, and electrical noise while ensuring uninterrupted operation.
Unlike conventional standby UPS systems, the ATEN Online UPS OL3000HV continuously converts incoming AC power into DC and then back into stable AC power. This process eliminates transfer time during power failures, ensuring that connected equipment experiences zero interruption even during unexpected outages or unstable utility power.
With an output power factor of 1.0, the ATEN Online UPS OL3000HV delivers maximum usable power for servers, networking equipment, storage systems, and other critical infrastructure. Its precise output voltage regulation of less than 1% provides stable performance for sensitive electronic devices.
The UPS features programmable power management outlets, allowing users to prioritize critical equipment during power failures. Non-essential devices can be automatically disconnected to extend battery runtime for mission-critical systems.
For flexible monitoring and management, the ATEN Online UPS OL3000HV supports USB, RS-232, and SNMP communication simultaneously. IT administrators can remotely monitor battery health, load levels, runtime, and UPS status through compatible power management software, enabling automated system shutdown and proactive maintenance.
A bright multifunction LCD display provides real-time information, including input voltage, battery capacity, output status, operating mode, load percentage, and estimated backup time. The intuitive three-button interface simplifies configuration and daily operation.
