Uninterruptible Power Supplies from 100 to 800 kVA

SLC X-TRA: High performance protection for major
critical applications

TheSLC X-TRAseries is one of the most reliable, high-performance
three-phase Uninterruptible Power Supply system (UPS) on the
market, and provides protection and quality energy for a wide range of
applications. Based on the Voltage and Frequency Independent (VFI)
mode of operation, it has been developed using double conversion
IGBT technology with DSP control, which gives considerable savings
in the costs of operation and installation while it offers maximum
protection for the connected loads.

This series has been conceived to offer the best guarantees in
meeting customers’ requirements and needs and has been designed
in full respect of the most demanding environmental regulations.

The SLC X-TRA series features power range from 100 to 800 kVA
in a very compact format for easier installation. Plus, the reliability of
the system can be increased with the installation of several redundant
units or it can grow in parallel based on the needs of the installation.

Applications: Guaranteed energy for all
environments

Data centres: Ensures the functionality of environments and
prevents losses caused by net failures.
IT-Networks: Prevent costs due to service interruptions or loss of
information.
Financial services: Maintains online operability of financial
transactions and operations.
Industrial processes: Protects productivity in electrically
complicated environments.
Telecommunications: Prevents supply failures that can suspend
communication between subscribers.
Infrastructures: Safeguards the instruments/equipment and
ensures the proper management of the systems

Parallel growth

The parallel UPS can be configured to achieve
redundancy or increase the power capacity
of the system. Parallel control is fully digital
and works for active as well as reactive
power in each phase, achieving an exact
load distribution between the UPS units in
transitory conditionsrs, y compris dans des
conditions transitoires.

High efficiency

High performance both On-line mode
(between 95% and 96%) and Smart Eco­mode (>98%), reducing operating costs,
implementation costs (no need to oversize
the wiring), air conditioning costs (without
increasing cooling requirements) and working
costs (saving energy consumed).
