LEGRAND 311342 KEOR DK 3000VA IEC

This high-performance online uninterruptible power supply (UPS) provides reliable protection for critical equipment, ensuring continuous power supply and stable voltage even in the event of network disturbances. Capable of delivering up to 3000 W (3000 VA), the device is ideal for powering servers, network devices, industrial systems or office infrastructures. Advanced online technology guarantees full filtering and power supply without switching times, while the built-in battery and efficient energy management system ensure optimal operation. The communication connections – USB, RS-232 and SNMP – enable the device to be integrated into a network and remotely monitored.

It is designed for professional use: in its 440 mm wide, 640 mm deep and 88 mm high housing, it weighs 27 kg and ensures robust, yet energy-saving operation. In addition to 93% efficiency, the Eco mode achieves energy utilization of up to 98.3%. The device works reliably in an operating temperature range of 0–40 °C, with IP20 protection, and its noise level is only 45 dB. Efficient voltage regulation, a potential-free contact, and an automatic switch-off function further increase safety and the life of the devices.
