Emerson Network Power launches flexible rack/row UPS

Emerson Network Power has launched the Liebert® APS uninterruptible power supply (UPS) with FlexPower™ technology. The system can achieve up to 92 percent efficiency in double-conversion mode, making it the highest efficiency UPS in its class. It also supports power requirements of up to 20kVA/18kW. It eliminates the need for UPS oversizing, maximising operational efficiency and contributing to minimise the UPS total cost of ownership (TCO).The Liebert APS UPS is available globally.

To enhance system availability, the Liebert APS UPS has a fully redundant design, allowing the critical load to run on conditioned power regardless of any single failure within the system. It has a wrap-around maintenance bypass, so the connected load can keep running while the system is being serviced. Its modular scalability allows Liebert APS users to quickly add power capacity or back-up runtime to support changing power requirements without powering down the connected loads. The Liebert APS UPS is enabled with Emerson’s LIFE™ remote diagnostic technology, which provides proactive maintenance, decreasing the average Mean Time to Repair (MTTR) and improving Load uptime.


“The pressure on IT managers to avoid downtime, and its respective impact on business critical functions, is more important than ever with growing IT loads. Coupled with the mounting pressure to improve both energy and operational efficiency, it is vital to have the ability to monitor technology applications in real-time,” said Franco Costa, vice president and general manager, AC Power Business for Emerson Network Power in EMEA. “With the Liebert APS, organisations can have peace of mind, with a highly dependable UPS that can easily increase capacity and can grow without downtime.”


The Liebert APS is designed for small- to medium-sized sites that expect increasing power requirements as they upgrade to larger servers, add storage capacity and use more powerful processors to meet growing demand for resource-intensive applications. FlexPower modules allow power capacity to grow in 5kVA /4.5kW increments up to 20kVA/18kW. Battery modules may also be added as needed to increase backup time. FlexPower modules and battery modules are hot swappable, and can be added or replaced seamlessly.


The Liebert APS UPS can be installed in any data centre or network environment – on raised or non-raised floors, or in standard rack enclosures. Three IntelliSlot ports allow multiple modes of communication and control. The Liebert APS is compatible with Emerson Network Power’s data centre infrastructure management (DCIM) system, the Trellis™ platform, and is also compatible with the Liebert Nform and Liebert SiteScan™ monitoring and reporting systems and with Liebert MultiLink™ shutdown software for reliable and safe shutdown of protected applications.
