WHITE PAPER
THE UPS IN DATA CENTERS AND THEIR MAIN FEATURES
MAINTENANCE AND SERVICING
Maintenance service combines the benefits of preventive maintenance and emergency
service for a service entirely tailored to customer needs, considering individual operational
constraints, business activity and the unique level of criticality associated with specific
applications, minimizing business interruption and the costs of downtime, as well as
extending the lifespan of critical power equipment.
Legrand’s UPSs are built on the latest developments in power management and proven
technologies, in order to make them reliable and resilient and to keep low maintenance
and servicing costs.
ADVANCED BATTERY MANAGEMENT
Batteries are the most critical component in the reliability of any UPS. Extending battery life can provide significant
savings, while neglect can be costly.
To ensure power supply continuity in the event of a power failure, the batteries must be charged and in good condition.
Therefore, a part of the energy absorbed by the UPS must be directed to charging the batteries. This is an additional
consumption that cannot be eliminated.
Legrand Smart charge battery technology is a unique three-stage charging technique that significantly extends battery
service life and optimizes recharge time, compared to traditional trickle charging.
This system is based on the direct measurement of the operating parameters (Voltage and current) of the batteries
and their variations in order to monitor the status of the battery in real time. The recharge follows a cycle consisting of
several stages, whose duration and intensity depends on the state of the batteries.
This advanced battery charge system has the benefit of having a fast charging time and the batteries are always charged
constantly monitored.
At the same time this system does not stress the batteries, because when they reach their full charge, the charging
intensity decreases until it reaches zero.
In other words, the smart battery charge system optimizes energy adsorption by limiting it to the amount actually
required by the real charging status of the batteries. Moreover, it has the additional effect of extending the batteries’
performance and life.
Intelligent Battery Charge System
(Smart Battery Charger)
The Smart Charger three-stage intelligent charging system considerably extends batteries’ life by even 50 %, thereby
halving the number of times they need to be replaced and environmental pollution due to their disposal.
