Cabinetized Next-Generation Platform Delivers up to 440 Amps Redundant for COs, POP Sites, Co-location Sites, Outdoor Cabinets, CEVs, Vaults, and other Smaller Telecom Applications.

LORAIN, OH September 19, 2004 -- Emerson Network Power, Energy Systems, a business of Emerson (NYSE: EMR), announces the introduction of the Lorainź eXpandable Power (LXP) system. This next-generation platform incorporates a new controller family, advanced controller intelligence, and a compact rectifier design that is capable of constant power output. It provides 67% more current in 60% less rack space than previous designs. Increased power density results from new, more efficient rectifier circuits that create less heat and require less cooling--distinct advantages in applications where cabinet space is at a premium.

The compact LXP platform includes a modular rectifier shelf system, 1500-watt 120/208/240 VAC rectifier modules, a controller module and distribution cabinets. Each 23" 2 rU shelf accommodates up to six rectifier modules, while each 19" shelf accommodates up to five rectifier modules. Users can minimize initial investment by configuring systems with outputs as low as 25 amps (1 rectifier module), later expanding them to a maximum capacity of 440 amps (17 rectifier modules providing N+1 redundancy) as power requirements grow. Each 3 rU distribution cabinet has a maximum current capacity of 300A and features easy front access to bullet-style breakers, TPS-style fuses and GMT-style fuses.

"When the controller is programmed for constant power, the rectifiers deliver more current during high switching load conditions or to meet battery recharging demands when excessive voltage drops occur and rapid recovery is required," said Dennis DelCampo, Vice President of Marketing, Emerson Network Power, Energy Systems. In the constant power mode, the maximum output of each rectifier is 1500 watts.

The constant power mode complements enhanced battery management features available with the LXP system. Based on the patented Telcordia battery algorithm, these features include reserve time; current limit; float current monitoring; individual cell, half-string and full string monitoring; and discharge testing--in addition to standard temperature compensation, thermal runaway management, system condition monitoring and functionality testing.

The LXP controller is designed for failsafe operation and includes a two-line, 16-character display, menu navigation keys and LED status indicators. Four binary inputs and six Form C alarm contacts,--all user-programmable,--enable system status communication. In addition to traditional alarms and controls, the system features a loss-of-redundancy alarm, activity and alarm history logs, inventory functions that include rectifier and battery age tracking, and a sequential rectifier start capability. For remote monitoring of unmanned installations, the controller incorporates web-based software and an RJ45 connection for access via Ethernet, TCP/IP or SNMP protocols.

LXP systems meet the strictest telecom safety and performance standards. They are NEBS level 3 compliant, UL listed and meet FCC Class B EMI/RFI requirements. Their rugged design is rated for continuous operation from -40șC to +80șC. Each of the "hot-swappable" modular rectifiers has an integral cooling fan and will deliver 100% rated power (on 208/240 VAC input) at temperatures as high as 65șC. As the temperature increases from 65șC to 80șC, the thermal current limit circuit linearly decreases current. In the typical operating range, these rectifiers have a power factor greater than .99, total harmonic distortion less than 5%, and efficiencies greater than 91.5%.
