Liebert APM UPS, 15-90kW



The row-based Liebert APM is a transformer-free, on-line uninterruptible power supply (UPS) that allows quick and easy capacity increases with modular scalability--with no additional floorspace required. Liebert APM operates with the industry's highest data center power efficiency--up to 94% at loads of 50-100%.


The 208 Volt, three-phase Liebert APM is available in two models, expandable with modular power scalability:

•Liebert APM 45kW frame size is expandable from 15 to 45kW, with up to 45kW of capacity, or up to 30kW of capacity with a 15kW module for redundancy. This frame size includes internal batteries, and is compatible with the matching external battery cabinet and the optional Liebert APM bypass distribution cabinet (BDC).


•Liebert APM 90kW frame size is expandable from 15 to 90kW, with up to 90kW of capacity, or up to 75kW of capacity with a 15kW module for redundancy. This frame size requires the matching external battery cabinet, and is compatible with the optional Liebert APM BDC bypass distribution cabinet.


•Scalable UPS protection for growing data centers

•Modular power offers capacity growth without increasing footprint

•Operates with the industry's highest efficiency rating - up to 94%

•Fits row-based applications


Liebert eXM UPS, 10-250 kVA/kW

Liebert-eXM-UPS-with-MBC-and-BAT-large large

The Liebert® eXM UPS is based on a reliable, double conversion  power topology that uses an efficient transformer-free design.  Operating efficiencies as high as 96% are generated in double-conversion mode and as high as 99% using our unique Eco Mode. The unity power factor delivers more capacity in a smaller.


Scale in 20kW increments from 10-200kVA/kW (208V) or 50kW in 50-250kVA/kW (480V) utilizing a modular construction design with optimized ancillary cabinets. The new Touch-screen Control Panel uses “glove friendly” technology that is both easy to read and use to reduce errors and enhance control.


Intelligent controls and network communications integrate with Liebert Nform, SiteScan and the Trellis Platform as well as 3rd party DCIM, BMS and monitoring systems. LIFE Services provides 24x7 remote monitoring by our expert staff to improve availability and lower labor costs.

•Scalable design provides rapid deployment changes to capacity or redundancy.

•Touch-screen UPS Control Panel provides “glove friendly”, intuitive operation that reduces errors and provides the right information to the right users.

•Unity Power Factor ensures more power is provided in a smaller footprint, thus increasing system capacity while minimizing cabling and installation costs.

•Industry leading efficiency rating: 98% for double conversion mode (480V), and 99% for Eco Mode

•Optimized ancillaries provide small footprints for better use of space.

•Comprehensive, easy to use LCD interface.

•ENERGY STAR®  qualified.

•UL924 for Emergency Lighting

•Native 208V or 408V
