Uninterruptible power supplies 80 to 400 kVA

High critical power facilities protected by high functionalities

Salicru’s SLC X-PERT series consists of three-phase UPSs that combine very low total cost of ownership (TCO) with very high efficiency and compact design, providing high-quality uninterruptible power for all critical applications. The technology incorporated offers one of the highest efficiencies on the market in VFI mode and 100% of expected battery life.


The SLC X-PERT series maximises the use of the surface occupied thanks to its high power density design. Models from 200 kVA have complete front access, precluding the need for side or rear space, making them easy to maintain and installable side by side, back to back or against a wall. The common battery option further enhances the ability of the SLC X-PERT series to deliver low footprint solutions, freeing space for other equipment.

High-efficiency mode:

High-efficiency operating mode disconnects the DC bus battery when it is fully charged, enabling the DC voltage to be lowered to achieve performance of up to 97% working in on-line mode and in turn protecting and extending the life of the batteries.

Parallel systems featuring UPSs with different powers

For cases in which there is only one UPS and, due to expansion needs, it is necessary to install another device in parallel, the SLC X-PERT series enables two devices with different powers to parallel each other in parallel systems of 2 units. For example, a power of 125 kVA with a 100 kVA device.

Parallel/redundant kit

Parallel/redundant kit

A kit for installations needing to grow in power or redundancy in the system, enabling the different units to be interconnected.

Ethernet/SNMP Web Adapter

Ethernet/SNMP Web Adapter - SALICRU

SNMP adapter to integrate the equipment in a IT network by using an IP address. It includes adapter, CD with programming software, configuration cable, MIB (Management Information Base) and user manual. Available in card or box formats.

MODBUS Protocol


Public and industrial communication protocol that allows controlling and monitoring of the device. Communication over an RS-232 port.

External manual bypass

External manual bypass - SALICRU

External Manual Bypass to make maintenance tasks, by isolating the equipment electrically. Bypass type make Before break

Top cable entry

Top cable entry - SALICRU

To facilitate suspended ceiling, cable tray or aerial electrical installations, the power cable entry is on the top of the equipment.

Isolation transformer

Isolation transformer - SALICRU

Electrical device that provides galvanic isolation between input and output, and adjust tension.

Backfeed protection

Backfeed protection

Backfeed protection provides additional protection to the input in the event that the bypass thyristors suffer a short circuit. Use of the internal backfeed contactor in the bypass line provides security in fault situations occurring in the static bypass line and prevents power from rising in the input.

Battery modules

Battery modules

For backup requirements greater than standard, one or several battery modules connected to the UPS can be installed.

Common rectifier/bypass input

Common rectifier/bypass input

For installations where only one electricity connection is available to power the UPS, it is possible to connect both inputs (rectifier and bypass) using a cable jumper.

NIMBUS adapter for remote management

NIMBUS adapter for remote management

The NIMBUS adapter has two versions:

- SNMP adapter version, which enables the device to be integrated into a computer network using an IP address. Management information bases (MIB) are provided for correct integration into the system.

- Remote maintenance service through an Internet connection, making it possible to know the state of a complete system of devices at all times and to overcome possible device faults, and providing a constant global view of the installation and all kinds of graphics and statistics.

External output voltage synchronism

External output voltage synchronism

The Load Sync option enables the output of the UPS to be synchronised when working in the inverter phase with an external power supply. Two versions available: Load Sync for single devices and Load Sync for parallel systems. Load Sync for single devices synchronises the inverters of two totally separate devices, while the Load Sync for parallel systems performs the same function but between two or several UPS systems connected in parallel. In order to connect both devices/systems correctly, it is necessary for them to be at a distance of less than 10cm.
