SLC X-PERT Uninterruptible power supplies 80 to 400 kVA SLC X-PERT 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 supply 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 floor area 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.

Efficiency Availability High-efficiency mode Dedicated electronic devices and control algorithm, which allow the batteries to be dynamically isolated from the device’s DC bus so that the inverter can be powered at a lower DC voltage. By working at a lower DC voltage, inverter switching losses are drastically reduced, and high energy efficiency of up to 97% is obtained, now from low percentages of output load. + | VDC | | | | | | | | --- | --- | --- | --- | --- | --- | --- | | | | |

By switching in voltage jumps of half the magnitude, stresses and losses on the IGBTs are reduced, as is the current ripple in the magnetic elements. The total efficiency of the device in double conversion (fully protected loads) can reach a maximum of 97% . Eco/Mode selection Selectable operating mode where the loads are powered directly by the static bypass while it is within the acceptable voltage and frequency ranges. Increased overall efficiency of the system up to 98% . Paralleling of devices Ability to parallel systems with up to 6 units (allowing up to 2.4 MW of power to be reached), both for redundant systems, and to increase power capacity. N+M redundant systems enable critical loads that should be protected with ‘N’ devices to have a redundancy of ‘M’ devices to replace the possible failure of any device, without compromising power supply continuity. Example: a ‘2+1’ SLCX-PERT 200 kVA parallel redundant system makes it possible to power a load of up to 400 kVA, which is tolerant to the failure of one of these 3 UPSs, without the need to transfer to static bypass. In other cases, the need to parallel devices may be due to increase

FAQs

What applications is the SLC X-PERT UPS series intended for?

It provides high-quality uninterruptible power for all critical applications and high critical power facilities.

How does the high-efficiency mode improve efficiency?

Dedicated electronic devices and a control algorithm dynamically isolate batteries from the device’s DC bus so the inverter runs at a lower DC voltage, enabling energy efficiency up to 97%.

What redundancy and scalability options does the series offer?

It supports parallel systems with up to 6 units for redundancy or capacity growth, including N+M redundancy to replace a possible UPS failure without compromising supply continuity.
