The Legrand external battery module expands the capacity of compatible uninterruptible power supplies (UPS), ensuring a reliable power supply for connected electronics during a power outage. The module is installed in a 2U rack and is compatible with line-interactive topology systems. Weighing 28.7kg and with compact dimensions of 88 × 440 × 440mm, it offers a dependable solution for stabilising the energy supply in a corporate environment. The device efficiently extends the backup time and helps prevent the unexpected loss of important data in critical situations.

Topology and power

This external module is designed to work with line-interactive topology systems, which effectively compensate for voltage fluctuations in the mains. The module supports systems with an apparent power of 3000VA. This solution enables the UPS to react reliably to power outages and provide a stable power supply for connected network devices without any interruption to their operation.

Battery and protection

The module contains a total of 6 built-in VRLA batteries, which use lead-acid technology for a long service life. The halogen-free construction ensures safe operation and eliminates the release of toxic gases in the event of overheating. The device requires an operating temperature between 20 and 25°C for optimal performance and can be safely stored in temperatures from 0 to 50°C.

Construction and installation

The module is designed for installation in standard rack cabinets, where it occupies a height of 2U. The sturdy chassis reliably protects the internal components from external damage and facilitates integration into existing server infrastructure without the need for complex structural modifications.
