3-Ph Hot Swappable Modular UPS- 20KVA to 200KVA
MURM200/20 series is modular online double conversion UPS for sensitive equipment’s. The single cabinet power rating covers from 20KVA to 200KVA which delivers the best of combination of reliability, hot-swappable and flexibility. With the latest IGBT three-level technology and DSP control, MURM200/20 achieves a high input power factor and significantly low THDi.


  • Capacities from 20kVA/18KW to 200kVA/180KW in 20kVA modular steps
  • N+1 Redundancy (up to 180kVA)
  • Full DSP control of high stability, reliability and safety
  • Integrated IGBT module with improved performance and reduced size
  • Excellent input performances for complete compatibility with input PF of 99% and
  • Wide input range of voltage i.e 228V to 476V & 40-70Hz frequency window
  • Self-Aging mode for full load test with less than 10% of the total power capacity needed
  • Maximum availability - ‘Six nines’ (99.9999%) availability by uniquely combining the benefits of parallel redundancy and ‘hot-swap’ modularity to ensure 24/7 power availability
  • High energy efficiency total flexibility & low total cost of ownership – The combination of high energy efficiency up to 98% and scalable flexibility using ‘hot-swap’ modules ensures that MURM200/20K offers a low total cost of ownership
  • UPS modules can be simply added, in cost effective incremental steps as the critical load power requirement grows. This ensures the UPS is ‘rightsized’ at initial installation, reducing the system’s initial cost, optimizing its operating efficiency and reducing ongoing operating costs
  • Smart charging management system, intelligently control the whole process of the charging and discharging $ effectively improve the life time of the battery
  • Independent charger for batteries, intelligent battery management system
  • Battery cold start, UPS can be powered on from the battery without utility
  • Totally front access, top and bottom cable connection
  • Friendly human machine interface with larger touch screen
  • Quick and simple power upgrade or repair by ‘Hot-Swapping’ modules while the UPS is online maximizes availability and simplifies system upgrades
  • High operating efficiency across a wide load range (90% to 95% efficiency from 25% partial load to 100% full load) reduces system running costs and site air conditioning costs, reducing CO2 emissions
  • Small footprint – 200kVA (180kVA N+1) delivering a power density of up to 465kW/m2 – allowing substantial space savings even at the highest capacity requirements
  • 0.9 Output power factor and 0.99 ~ unity power factor at Input side
  • Low input harmonic distortion (THDi<3%)


  • Critical applications wherever higher reliability is needed
  • Medical & lifesaving equipments
  • Data centers & Larger computer rooms
  • Industrial & Petrochemical application
  • Banking & Telecommunication
  • Power Generation & distribution stations
