Magnizon-3-PH UPS, 250KVA

MURM250/50K

Overview

MURM250/50K Smart hot swappable Modular UPS with unity power factory provides the most compact footprint of less than 2m2 with maximum capacity of 1MVA with high performance. Smart modular UPS is a scalable three-phase In/Out uninterruptible power supply system with DSP technology and provides true on-line double conversion power protection. The available UPS power and redundancy level can expand vertically from 50 to 250 kVA / 250 kW in one single power cabinet, and four power cabinets can be connected in parallel, increasing the capacity up to 1MW. It features modular hot-swappable design, all modules support “plug & play”, including power modules, bypass module, and control module, simplifies UPS servicing and maintenance.

Applications

  • Critical applications where ever higher reliability is needed
  • Medical & lifesaving equipment’s
  • Data centers & Larger computer rooms
  • Industrial &Petrochemical application
  • Banking & Telecommunication
  • Power Generation & distribution stations

Key Features

  • Capacities from 50KVA/50KW to 250KVA/250KW in 50KVA/50KW modular steps, N+1 Redundancy (up to 250KW)
  • Full DSP control of high stability, reliability and safety
  • Friendly human machine interface with colorful touch screen of 7 inches
  • Independent LCD display for each power module with self-starting function
  • Integrated IGBT module with improved performance and reduced size
  • Automatically record the critical wave information when fault happen, easy for trouble shooting
  • Monitor runtime of critical components, such as fans and capacitors, settable alarm for service period
  • 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 MURM250/50K 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
  • Quick and simple power upgrade or repair by ‘Hot-Swapping’ modules while the UPS is online maximizes availability and simplifies system upgrades
  • High power density with footprints of less than 2? up to 1MVA in parallel, 50KVA power module with height of only 3U
  • 0.99 Output power factor  and 0.99 ~ unity power factor at Input side
  • Low input harmonic distortion (THDi<3%)
