UPS Legrand Keor DK 311345

The Legrand Keor DK 311345 is an On-line Double Conversion UPS (VFI-SS-11) with a capacity of 1000 VA / 1000 W, providing continuous and stable power for sensitive equipment such as servers, network systems, and industrial devices.
It features a flexible convertible design for tower or 19” rack (2U) installation, equipped with a touchscreen display and intuitive LED status bar for easy monitoring and operation.

Key Features

On-line Double Conversion (VFI-SS-11) technology delivers a pure sinewave output, fully isolating connected equipment from electrical noise and voltage fluctuations.
High efficiency up to 92%, saving energy and reducing heat generation.
Wide input voltage range (176–280 V) ensures stable operation even under fluctuating mains conditions.
High input power factor (>0.99) minimizes power loss and optimizes performance.
8A charging current supports external battery expansion for longer backup time.
Integrated EPO, SNMP, ROO, and dry contacts allow seamless integration into centralized management systems.
Low noise level ( makes it ideal for quiet environments such as offices or control rooms.
Compact 2U design with IP20 protection, compliant with EN 62040-1, EN 62040-2, and EN 62040-3 international standards.
