Vertiv Liebert RX Distribution Cabinet
Industry’s Smallest Footprint; 400 Amp, 84 Poles

Overview:

The compact Vertiv Liebert RX cabinet is available with panelboard level or branch circuit level monitoring, and can be used in 1 - 4 unit space-saving configuration blocks.

A Space-Saving, Flexible Solution for High Density Power Distribution

The influx of client/server rack equipment is changing the content of data centers. There are more devices than before, and they consume more power than their predecessors. Space is at a premium, so the data center power support infrastructure must be compact and flexible, to meet changing room demands.

The Liebert RX remote power distribution cabinet supplies packaged power distribution in the smallest possible footprint, with 400 Amp and 84 poles in one panelboard, and only requiring 24”x12” of space. It offers monitoring options and multiple configuration possibilities to fit the needs of most data centers. Liebert RX is available in 400A, 84 pole models, with options for panelboard level or branch circuit level monitoring. The compact cabinet may be used in a stand-alone configuration, or may be clustered in space-saving 2, 3 or 4 unit configuration blocks.

Flexibility

• 84 poles in a 24”x12” footprint. Up to 168 poles in a 24”x24” footprint
• Multiple configuration options allow optimization of data center space – two, three or four units may be installed in space-saving clusters
• Floor or wall mount, or attach to supports at end of rack aisle
• Fits standard raised-floor tile, while permitting removal of adjacent floor tiles

Higher Availability

• The 400A continuous current rated main circuit breaker better coordinates with today’s 30A and 60A branch breakers than smaller 225A mains, providing better selective tripping
• Each panelboard is totally isolated – any potential arc flash is contained within the cabinet when installed back-to-back and each is receiving a separate feed from a dual bus system
• Factory assembled and tested to ensure reliability and consistent performance
• Wide open access channels provide six inches of access space, and individual hinged covers, allowing easy addition of future circuits

Lowest Total Cost Of Ownership

• Compact cabinet conserves valuable floor space
• Packaged system is easy to install, maintain and add additional circuits

Ideally Suited For

• Data centers
• Telecommunications
• Manufacturing

System Monitoring

The Liebert RX is available with two monitoring options: at the panelboard level with Current Plus Monitoring (CPM) and at the panelboard level and the branch circuit level with Liebert Distribution Monitoring (LDMF).

Panelboard Monitoring:

The integral Current Plus Monitoring (CPM) optional display monitors the current and voltage of the panelboard. The display includes a monochrome LCD, power and alarm LEDs, audible alarm, and a silence push button. It provides true RMS measurements and battery backed memory.

Monitored parameters include:

• Voltage - Line-to-Line
• Voltage - Line-to-Neutral
• Neutral Current
• Ground Current
• kVA
• Power Factor
• Voltage Total Harmonic Distortion (THD)
• Current Total Harmonic Distortion (THD)
• Crest Factor

Branch Circuit Monitoring:

Advanced monitoring is available through the optional Liebert Distribution Monitoring (LDMF) display. This option provides a large LCD screen that allows viewing of monitored information for the panelboard as well as each individual branch circuit breaker. Alarm data may be viewed from this display for up-todate breaker status. It provides true RMS measurements and battery backed memory.

Monitored parameters are the same as those for the CPM monitor, plus for each branch circuit:

• Phase Current
• kW
• kW- hours
• Percent load

Centralized Monitoring:

• An optional Liebert SiteScan Web interface allows centralized monitoring of the Liebert RX.
• A Liebert IntelliSlot Unity communications card allows monitoring via a Building Management System (BMS) or IT network with multiple protocols (SNMP, Modbus, BACnet) in one card.
