UPS Keor DK 311340 1000 VA, 2U

Description of UPS Legrand Keor DK 311340

Keor DK 311340 is a 1-phase UPS using On-line Double Conversion VFI technology, 2U size (19” rack) / converted to tower, rated capacity 1 kVA ~ 1 kW (PF = 1).

This UPS is a basic, compact, easy-to-install version, managed by touch screen and standard communication ports. With a design for small depth racks, integrated internal battery, suitable for small servers, important network equipment, camera systems / security equipment, small data rooms and office applications that require clean power and short backup time.

Outstanding features:

• Real capacity 1 kW (PF = 1).
• On-line Double Conversion technology (VFI-SS-11) - completely separates the load from the grid, providing the highest protection for sensitive loads.
• Convertible design 2U (19” rack) / tower - space saving rack space saving, suitable for 600 mm depth cabinets.
• Touch-screen + LED indicator, with gravity sensor to display the correct direction.
• Internal battery - this model comes with an internal battery; reference backup time ~9 minutes.
• High operating efficiency: AC/AC ≈ ~92%; when ECO Mode is on, it can reach ~98% (saving mode).
• Wide input voltage range: stable operation under fluctuating grid power conditions (about 176 V - 280 V at full load).
• Protection & operating features: Cold-start, backfeed protection, EPO (Emergency Power Off), integrated ROO/relay contact (dry contacts).
• Communication & management: USB, RS-232, ROO; SNMP/BMS card connection possible (configuration option).
• Lithium battery ready and supports external charger/upgrade charger (8A optional) to increase runtime if required.
• Standards & safety: EN 62040-1/2/3 compliant; IP20 protection rating; 0–40°C operation.
