Product information

Description

The Legrand Keor DK 311348 is an advanced online double-conversion uninterruptible power supply engineered to provide reliable backup power and electrical protection for sensitive equipment. Delivering a robust output power capacity of 5 kVA and 5000 W, this single-phase UPS utilizes high-frequency PWM technology to ensure a steady, high-quality power supply. Featuring a versatile rackmount and tower convertible form factor in a sleek black finish, it integrates seamlessly into server rooms, data racks, and office environments while offering clear operational status monitoring through its intuitive LCD display and RS-232 serial interface.

Advantages

This uninterruptible power supply offers exceptional energy efficiency, reaching a peak efficiency of 96% through advanced AC-AC technology to minimize operational costs and thermal output. The online double-conversion topology ensures zero transfer time to battery power during grid anomalies, completely isolating connected devices from voltage fluctuations, sags, and surges. Its unity power factor design guarantees that the apparent power equals the real power, maximizing the available active power for connected loads. Maintenance is simplified through hot-swappable battery blocks and a user-friendly touch screen control panel with interactive icons.

Suitable for

  • Protecting enterprise servers, data storage systems, and critical networking hardware
  • Safeguarding sensitive electronic equipment in small to medium business IT infrastructures
  • Ensuring continuous operation for telecommunication setups and security systems

When it may not be suitable

This unit is not designed for heavy industrial machinery requiring three-phase power inputs or extremely high continuous loads exceeding its 5000 W rating. It may also be oversized and unnecessary for basic home office setups or single desktop computers with minimal power backup requirements.

Key specifications

  • Double-conversion online UPS topology
  • 5 kVA output power capacity and 5000 W output power
  • Rackmount and tower convertible form factor in black
  • Sealed Lead Acid VRLA battery technology with hot-swappable blocks
  • RS-232 serial interface for communication
  • Input operation voltage range from 176 V to 280 V
  • Input frequency range of 45 to 65 Hz
  • LCD display for status monitoring

How to use

Position the unit in either a rackmount configuration or as a tower depending on your spatial setup, ensuring adequate ventilation around the device. Connect the input power cord to a suitable mains outlet matching the operational voltage range of 176 V to 280 V. Plug your critical electronic devices into the designated output receptacles on the UPS. Power on the unit using the touch screen LCD control panel, which will guide you through initial status checks and allow you to monitor operational parameters in real time.

What to consider before purchase

  • Verify that your total connected load does not exceed 5000 W to prevent overload conditions
  • Check available physical space for rackmounting or tower placement
  • Assess your runtime requirements and evaluate whether standard sealed lead acid or compatible lithium batteries suit your operational needs

For optimal performance and battery longevity, install the UPS in a temperature-controlled environment away from excessive dust and moisture, and perform routine functional tests using the LCD control panel.

Design

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
