Product Overview
Kehua’s MR33 Series 30-1200kVA MODULAR UPS is a 3-phase online double-conversion solution for critical power protection and high-quality power supply of medium and large data centers. UPS with hot-swappable modules, the power capacity starting from 30kVA up to 1200kVA for a single cabinet, and there are 3 kinds of power modules which are MR3330-J, MR3350-J, and MR33100-J to satisfy the on-site requirements of different customers. They are available in 5 sizes, MR33120-300, MR33400-600, MR33600, MR33800, and MR331000-1200 with an efficiency of up to 97% and high reliability.
Key Features
High Reliability
High Reliability
Wide input voltage range -60%~25% and wide input frequency range 40-70Hz with high grid adaptability and prolong battery life.
All module hot-swappable design ensures uninterrupted operations during maintenance and easy for module replacement.
Power module with separate internal air channel which hot air drives directly towards heat sink without distressing the PCB's and other internal sensitive components, improving the components service life and UPS reliability.
Intelligent fan control and redundant design: 15% load can be driven when 2 fans fail and 40% load when 1 fan fails
Integrated with 4 ACB for 1.2MW with input, output, bypass breaker and manual bypass breaker for better protection of system.
Multilevel electrical isolation design, frame and modules equip with fuse, which isolate the abnormal condition and make sure safety.
No derating operate up to 40°C and continuously running under high ambient temperature up to 55°C with power derating.

Latest generation IGBT and three level technology, Low harmonic, high efficiency, effectively energy-saving.
High efficiency in online mode >97% reduces heat dissipation and limits power consumption costs
W-ECO mode efficiency could reach 99%, THDi below 5% and transfer time below 0ms to reduce TCO.
ECO mode efficiency up to 99.2% lead to significant cost reduction
Low THDi≤1.5% and input power factor 0.99 reduce the pollution to grid and reduce upstream investment costs
3U 100KW power module make sure utility output power (kVA=kW) to maximize power availability and high power density cabinet up to 600KW only 0.8m² and 1.2MW only 1.8m².
Self-load test function, easy debugging and easy onsite test during commissioning without using costly temporary loads, cabling and breakers for energy saving.
Intelligent sleep mode which UPS module sleep in random keep maximum efficiency and energy saving.
Intelligent Management
Intelligent Management
Fault Trace Management (FTM) for convenient failure analysis (waveform record before & after of the fault point for 200ms) which easily figure out faulty point.
Maintenance assistant locate the problem easily and quickly, Reduce time for maintenance.
Start-up guidance and diagnosis help to clear potential risk before power on the system.
Energy Storage Mode allow system working Intelligent peak cutting and valley filling, using the peak and valley electricity price difference, reduce TCO.
Intelligent battery management and multiple setting, 30-50pcs* batteries per string allow customers to get the faulty battery out instead of replacing it
Key components pre-alarm function which precaution the system fault and remind service for key components, like capacitor, fan.
Smart programmable dry contact which have 6 input dry contact and 3 output dry contact, which input dry contact have more than 10 functions and output dry contact have 18 functions allows to settable at site.
Common battery bank on parallel mode.
VRLA and Lithium battery compatible design
User-friendly Interface
User-friendly Interface
Double physical ON/OFF button design to avoid false operation.
User-friendly graphical interface with Single-line mimic diagram showing system status.
Colorful 7 inch touch screen with LED Indicators, ensure comprehensive and visualized information display.
Multicolor LED bar allowing quick and easy detection of the system status and simplified troubleshooting.
Multi-language build-in display with Chinese, English, French, Spanish, Italian, Polish, Russian, Korean, German.
Support firmware online update, one time update for touch screen, power unit, bypass unit and extended card.
Main unit display allows to check the information of each UPS status during parallel mode.
