Emerson Power Solutions Manuel D’Utilisation

Liebert and Knurr brand computer rack systems offer all the

advanced features and innovative flexibility required to

accommodate today’s dense and complex IT systems and

network gear. 

Knurr racks simplify equipment installation, improve cable

management and increase visibility and control of

equipment inside the rack.

Liebert enclosures integrate power and cooling to provide a

complete rack-based support system. Liebert pioneered this

approach with the Little Glass House and today provides

enclosures, such as the Liebert MCR and Liebert XDF, that

protect sensitive electronics in almost any environment.

Liebert offers all three major uninterruptible power supply

(UPS) system configurations:

n  

Off-Line UPS—Passes utility power straight through to the

protected load with a 2-6 ms break in power when

transferring to battery back-up. 

n  

Line Interactive UPS—Provides power conditioning with 

a 2-6 ms break in power when transferring to battery 

back-up.

n  

On-Line (Double Conversion) UPS—Delivers continuous, 

high-quality AC power to equipment with no break when

transferring to battery. Protects equipment from virtually 

all power disturbances due to blackouts, brownouts, sags, 

surges or noise interference.

Liebert offers UPS systems in the industry’s widest range of

sizes including desktop, rack-mount and enterprise systems

for full facility power.

Liebert offers a range of power distribution systems designed to

efficiently deliver conditioned power to your critical equipment.

These products include high-reliability distribution systems,

starting with rack power distribution systems, specially designed

for computer and communications applications, as well as

transfer switches offering ultra-fast transfer between two

independent AC power sources to provide virtually uninterrupted

power to sensitive electronic equipment.

For applications requiring protection from electrical line 

disturbances without the need for back-up capability, Liebert

manufactures a full line of power conditioning equipment. It

includes a wide variety of transient voltage surge suppression

(TVSS) solutions ranging from high-quality surge suppressors 

for use with PCs, workstations and other peripherals to 

facility-wide systems with sophisticated active tracking 

capability. Other products include power conditioning systems

featuring high-efficiency magnetic synthesizer technology 

and isolation transformers to reduce line noise and other 

power line problems.

From major switching centers to remote shelters, Emerson DC

power systems offer performance and features to match virtually

every telecommunications equipment application. The line

includes a variety of system capacities ranging from small 

systems at less than 3 kW up to large systems rated at over 

60 kW. The product offering also includes distribution bays, 

enclosures and network management products such as 

controllers, monitors and supervisory software to control and

maintain energy equipment in a telecommunications network.

Liebert’s family of power communications software and 

hardware provides multiple levels of monitoring and control.

Capabilities range from automated shutdown software to 

facility-wide centralized systems that provide a full range of

monitoring, control and analysis.
