UPS EXL 1200KVA chính Hãng Vertiv năm 2024

Liebert EXL delivers an outstanding double conversion efficiency of up to 97%, consequently reducing operating costs and energy dissipation (kW) to a minimum. This significantly minimizes the consumption of the cooling system, providing an overall TCO reduction and rapid payback time.

Furthermore, through its intelligent ECO mode efficiency and the intelligent paralleling feature Liebert EXL can optimize efficiency even at partial load achieving additional superior cost savings.

UPS EXL 1200KVA levels of efficiency and consequent electricity cost savings can be attribuited to:
• Latest generation IGBT
• Adoption of a three-level NPC2 topology for both rectifier and inverter
• DC controlled fan speed
• Intelligent paralleling mode
• Advanced digital technology and fast transfer

The seamless activation of Liebert EXL’s functioning modes ensures the highest level of efficiency without compromising power quality and availability.
Fast transfer technology ensures the quickest response time under various conditions:
• Network fault (voltage variation, high/low impedance mains failures)
• Load fault (short circuit downstream of the UPS)
• Type of load connected (PDU transformer)

The unit is able to discriminate between various types of interferences and rapidly respond, while at the same time ensuring compatibility with downstream equipment such as servers, transformers, STS or mechanical loads.

Double Conversion Mode (VFI) provides the highest level of power conditioning and protects the load from all electrical network disturbances

Intelligent ECO Mode (VFD) detects when conditioning is not required and allows the energy flow to pass through the bypass line.

Liebert EXL Intelligent Paralleling Feature

Activating the intelligent paralleling feature optimizes efficiency at partial load, thus achieving superior running cost savings. Enabling this feature allows the system to automatically adapt capacity to meet immediate load requirements by switching excess units to standby mode, while ensuring continued system availability.

Furthermore, the Intelligent Paralleling feature allows each Liebert EXL unit to operate in standby mode for the same amount of time, ensuring an equal lifespan of module components. This intelligent paralleling feature further maximizes Liebert EXL’s double conversion efficiency at partial load and allows for an overall energy dissipation and TCO reduction.

Parallel Configurations

The Liebert EXL can be connected with up to 8 units in parallel, where single units can be serviced while the remaining units continue to power the load. A Liebert EXL unit continues to operate even while it’s being upgraded to a parallel system due to the upgrade occurring via software settings. Furthermore, Liebert EXL is backward compatible with the previous 80-NET generation, so as to facilitate any legacy system power upgrade. Liebert EXL can support both distributed and centralized parallel configurations providing maximum energy saving via double conversion and intelligent ECO mode, allowing to operate with a
system efficiency of up to 99%.

Distributed Parallel Configuration

Paralleling single Liebert EXL units offers advanced scalability. In a distributed parallel configuration, each unit has a dedicated static bypass switch, providing parallel operation without the need for a system control cabinet, thus reducing initial installation costs.

Centralized Parallel Configuration

With the Liebert EXL’s centralized parallel configuration, the internal static bypass switch of each unit is disabled and an external Main Static Switch (MSS) rated for the desired maximum capacity, is installed. Therefore, the reserve supply to the loads operates via one central piece of equipment (MSS). The MSS can easily be integrated into any switchgear, thus simplifying cabling and installation. System level commands are given to the MSS via its integrated touch screen display.

User Interface and Advanced Diagnostic

UPS EXL 1200KVA makes your mission critical space a peaceful place through its advanced diagnostic capability, measuring and logging, enhanced event analysis as well as an intelligent colored multi-language touch screen display. Liebert EXL advanced DSP control platform together with the patented Vector Control technology enables increased performance of three-level power converters and real time control of output power quality, guaranteeing continuous operation and premium protection for your customer’s business.
