    The Legrand Keor DK is a high-performance uninterruptible power supply designed for critical applications that require continuous, clean, and reliable power. Built on Double Conversion On-Line technology with high-frequency PWM control, it delivers stable output with a power factor of 1, ensuring full utilization of its rated capacity. Its compact 2U rack design integrates both electronics and batteries, making it well-suited for space-conscious IT and network environments.


    Key Features of Legrand Keor DK UPS 1000 VA

    • Double Conversion On-Line UPS technology
    • Rated power of 1000 VA / 1000 W with PF 1
    • High-frequency PWM control for stable output
    • Integrated VRLA rechargeable battery pack
    • Compact 2U rack-mounted form factor
    • Wide input voltage range for improved adaptability
    • USB, RS-232, and SNMP communication interfaces
    • High overall and eco-mode efficiency

    Power and Performance

    The Keor DK delivers 1000 W of effective output power with zero compromise between apparent and active power. Its online UPS topology continuously conditions incoming power, protecting connected equipment from voltage fluctuations, frequency variations, and electrical disturbances. With an output voltage range of 200–240 V and low harmonic distortion of just 3% under linear load, it ensures consistent power quality for sensitive systems.


    Electrical Input and Output Characteristics

    Designed for single-phase operation, the UPS accepts a wide input voltage range from 110 V to 280 V and input frequencies between 45 and 65 Hz. On the output side, it provides a stable AC supply at 50–60 Hz. Six C13 output connections support multiple devices, while the C14 input connection allows straightforward integration into existing power infrastructures.


    Efficiency and Operating Modes

    With an overall efficiency of up to 92% in online mode and an impressive 98.3% in eco-mode, the Keor DK minimizes energy losses and operating costs. Intelligent power management features, including automatic shutdown and potential-free switch contact, enhance operational control and energy optimization in managed environments.


    Battery System and Runtime Support

    The UPS is equipped with valve-regulated, hermetically sealed VRLA accumulator batteries housed within a dedicated internal compartment. The integrated battery pack consists of three rechargeable elements, engineered for industrial applications and optimized for reliability and safety during continuous operation.


    Communication and Network Integration

    For monitoring and management, the Keor DK includes USB and RS-232 interfaces as standard, along with SNMP capability for network-based management systems. These interfaces allow administrators to monitor status, manage shutdown procedures, and integrate the UPS into centralized power management frameworks.


    Physical Design and Installation

    Measuring 88 mm in height, 440 mm in width, and 454 mm in depth, the Keor DK fits neatly into standard 19-inch racks while occupying only two rack units. Weighing 14.8 kg and rated at IP20, it is designed for controlled indoor environments with operating temperatures ranging from 0 to 40 °C.


    Acoustic and Environmental Characteristics

    The unit operates at a sound level of 45 dB, making it suitable for server rooms and technical areas where noise control is important. It supports universal load types and maintains stable performance across a broad range of operating and storage temperatures.
