Liebert NXe 30kVA 24kW On-Line UPS System - 3x3 SNMP-Web No Batteries

Today�s advanced digital computing, communications, process control and medical systems require power protection that is just as innovative. These systems, however, face many of the traditional threats to their availability - foremost among them is a lack of high quality power required to operate sensitive electronics. The system�s advanced True On-Line, double conversion topology features a digital signal processor (DSP) controlled IGBT rectifier and a digital signal processor (DSP) controlled IGBT inverter. DSP Power Factor Corrected IGBT Rectifier The rectifier provides = 0.99 Input Power Factor (PF), less than 3% of Input Current Total Harmonic Distortion (THDi) and the widest input voltage window and frequency tolerances. Near to Unity Power Factor ensures maximization of active power leading to reduced electricity pay-out, minimization of cables, associated switchgear and backup generator sizing requirements leading to reduced investment costs. Low input current THDi avoids disturbance to other loads connected upstream the power distribution bus without the need to oversize generator set. Wide input voltage window and frequency tolerances contribute to higher battery life by minimizing battery usage. High performance rectifier design helps low Neutral potential over ground and thus ensures safety of equipment. Emerson Network Power's goal is solving these challenges with a power solution that combines high performance, compact size, reliability and cost-efficiency. Emerson Network Power's Liebert NX is the Next Generation of True On-Line, Double-Conversion digital UPS. Designed to meet the high availability DSP Controlled IGBT inverter Advanced inverter control technology provides the highest output power quality, ensuring very clean output voltage waveform (very low THDv) to protect connected loads. It operates under a wide variety of conditions, handling 100% non-linear loads with 3:1 crest factor, as well as 100% unbalanced loading. The inverter control makes Liebert NX to be suitable for the widest ranges of loads required by the market; including 0.9 leading PF loads. power needs of a wide variety of applications, the Liebert NX combines innovation, simplicity and low cost of ownership. The result is a power system that delivers both reliability and a return on investment beyond what has been traditionally offered.
