EMERSON LIEBERT 7400M (20/30/40/60KVA)

Series 7400 M (10/20/30/40/60 kVA)
Maximum Protection For Mission Critical Network Applications
Compact Three-phase UPS with Optimum Load Performance And Battery Management System
Series 7400 M
Today’s electrical network cannot provide High Nine power quality. Many problems like voltage / frequency fluctuations, harmonics, transients, blackouts, brownouts are still present. They may cause your critical and sensitive systems to fail with negative impact on your business. The Liebert series 7400 M addresses all the power quality needs of today’s networked economy by providing a perfect sinewave output voltage with stable frequency, over and above offering many other important customer values.
On-line double conversion UPS: makes your load independent from both main’s voltage and frequency. Ensures server-grade high quality of power. IGBT technology PWM inverter switching technology: provides your load with perfect sinewave voltage. High efficiency performances: lower cost of ownership. Excellent performances with either 100% unbalanced and 100% non-linear loads with crest factor up to 3:1 without derating: no need to care about the distribution of your single phase loads between output phases nor to oversize the UPS. Super-servers, mini-computers and multi-processing systems. Advanced battery management systems with programmable battery testing: constantly monitors the health of the battery pack keeping the battery ready to work for emergency situations. Small footprint and convenient maintenance access: ease of positioning and saving of floor-space. Inverter with high overload capability: no need to oversize UPS; reduced Initial Investment. Inverter Output protected against short circuit: high protection to the inverter hence more availability of the systems; Investment Protection. Zero footprint for optional tuned filter for the input: lower cost of ownership because of space saving and reduced electricity bill. Output kW without deration up to 0.9 lead power factor.

Series 7400 M Compact 3-phase UPS With Optimum Load Performance And Battery Management System
Series 7400M An Outstanding Performer
The system's advanced true-online, double conversion topology features a Micro-processor based controlled, IGBT Inverter. Rectifier
PWM Based IGBT Inverter 
The rectifier provides   up to 0.99 Input Power Factor (PF), up to 3% of Input Current Total Harmonic Distortion (THDi)  with Optional configurations of Harmonic filters and the widest input voltage window and frequency tolerances.  
Advanced inverter control technology provides the highest output power quality, ensuring very low output voltage THD and superior waveform 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 enables 7400M to be suitable for the widest ranges of loads required by the market; delivering full active power rated kW up to 0.9 leading PF loads.
Input Isolation Transformer - Compatible with Liebert AF, the Active Harmonic Filter - Wide range of solutions specially designed for handling current harmonic on bypass at different stages - Available for rectifier and / or bypass supply Protection Degree (IP) For 7400M Enclosure - To address stressed environmental conditions, UPS with higher than IP20 degree of protection can be made available for most of the kVA ratings of 7400M DC Ground Fault Indication - This provides indication of occurrence of battery ground fault problems  i-Enersave Module - Purpose of this logic is to optimally load each UPS system in a multi UPS parallel system so that each UPS works in its most efficient band of operation while total installation being subjected partial load. This logic keeps minimum number of UPS system in Operation as per load demand. The choice of redundancy level is settable in the logic to have high up-time depending on criticality index of load, it has wide use in industries where load pattern is highly dynamic. - Auto Sleep and Auto sequencing options available with this logic ensures no UPS System is spared from regular health check up, if prolonged conditions persist. Thus enhanced efficiency of overall system reduces Energy cost and increased customer profitability.
This tacitly reduce consumption of natural resources, combustion of fossil fuel, hence reduction in green house gas emission and carbon footprint. Power Walk-in for 1 N System - The module power walk-in is standard. This option can be for the module restart delay after the mains return. This is very useful for applications with motor generator at the input LBS - This ensures the synchronisation of outputs of two Independent UPS systems to form Dual Bus Architecture for High availability of Critical Bus Liebert LTS, Static Transfer Switch - This allows critical load to be transferred between two independent, synchronised AC power sources without any risk of load disturbances - This allows automatic transfer of load between the two sources TVSS - This is a Transient Voltage Surge Suppressor - This offers protection from damaging transients and electrical line noises - This is normally connected at the I/P and O/P path of 7400M  as an optional item n n n n
