Product information

Description

The Legrand Keor DK 311341 Online Double-Conversion Uninterruptible Power Supply is a robust power protection solution designed to deliver a steady and reliable power supply for critical IT infrastructure. With a capacity of 2 kVA and an output power of 2000 W, this rackmount UPS utilizes advanced online double-conversion topology to isolate connected devices from utility power instabilities, voltage fluctuations, and complete outages. Featuring pulse-width modulation technology, a touch control panel, and an RS-232 serial interface, it integrates seamlessly into standard server environments while ensuring continuous equipment operation.

Advantages

This uninterruptible power supply offers true online double-conversion architecture, which completely eliminates power anomalies and provides zero transfer time to battery power during an outage. The unit maintains a power factor of 1, meaning its 2 kVA capacity delivers a full 2000 W of active power to connected loads. Its compact rackmount form factor saves valuable space in server racks, while the integrated touch control panel allows for straightforward local monitoring and management. Additionally, the inclusion of both C13 and C19 AC outlet types ensures broad compatibility with various server and networking hardware components.

Suitable for

Protecting rackmount servers and data storage units
Securing networking switches, routers, and communication hubs
Powering sensitive IT infrastructure in small and medium businesses
Maintaining uptime for critical automation and monitoring systems

When it may not be suitable

This UPS is not designed for standalone tower deployment without proper rack mounting infrastructure, as it is specifically engineered for rackmount environments. It may also exceed the power requirements of basic desktop computers or home appliances, making it less cost-effective for non-enterprise applications.

How to use

To set up the Legrand Keor DK online double-conversion uninterruptible power supply, mount the unit securely within a standard equipment rack using appropriate mounting hardware. Connect the input power cable to a stable utility power source within the specified voltage and frequency ranges. Plug your sensitive servers, switches, or networking equipment into the C13 and C19 output sockets on the rear panel. Power on the device using the touch control panel, which allows you to monitor operational status and configure settings as needed.

What to consider before purchase

Verify that your rack enclosure has sufficient depth and weight capacity to support the dimensions and mass of the UPS
Check that your connected equipment loads do not exceed the 2000 W active power limit
Ensure your facility has compatible AC outlet connections matching the C13 and C19 types
Confirm that an RS-232 serial interface aligns with your remote management requirements

Usage recommendations: Install the uninterruptible power supply in a well-ventilated server room where ambient temperatures remain within the 0 to 40 degrees Celsius operating range. Regularly inspect the touch control panel for any status warnings and perform routine maintenance checks to ensure optimal battery performance and longevity.

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".: IP20
